"I shall next describe a strange sort of animal, called by the white men
in this country Mandrill,* but why it is so called I know not, nor did
I ever hear the name before, neither can those who call them so tell,
except it be for their near resemblance of a human creature, though
nothing at all like an Ape. ([Footnote] *"Mandrill" seems to signify
a "man-like ape," the word "Drill" or "Dril" having been anciently
employed in England to denote an Ape or Baboon. Thus in the fifth
edition of Blount's "Glossographia, or a Dictionary interpreting the
hard words of whatsoever language now used in our refined English
tongue...very useful for all such as desire to understand what they
read," published in 1681, I find, "Dril--a stone-cutter's tool wherewith
he bores little holes in marble, etc. Also a large overgrown Ape and
Baboon, so called." "Drill" is used in the same sense in Charleton's
"Onomasticon Zoicon," 1668. The singular etymology of the word given by
Buffon seems hardly a probable one.) Their bodies, when full grown,
are as big in circumference as a middle-sized man's--their legs much
shorter, and their feet larger; their arms and hands in proportion. The
head is monstrously big, and the face broad and flat, without any other
hair but the eyebrows; the nose very small, the mouth wide, and the lips
thin. The face, which is covered by a white skin, is monstrously ugly,
being all over wrinkled as with old age; the teeth broad and yellow; the
hands have no more hair than the face, but the same white skin, though
all the rest of the body is covered with long black hair, like a bear.
They never go upon all fours, like apes; but cry, when vexed or teased,
just like children...."
(FIGURE 5.--"A Mandrill". Facsimile of William Smith's figure of the
"Mandrill," 1744.)
"When I was at Sherbro, one Mr. Cummerbus, whom I shall have occasion
hereafter to mention, made me a present of one of these strange animals,
which are called by the natives Boggoe: it was a she-cub, of six months'
age, but even then larger than a Baboon. I gave it in charge to one of
the slaves, who knew how to feed and nurse it, being a very tender sort
of animal; but whenever I went off the deck the sailors began to teaze
it--some loved to see its tears and hear it cry; others hated its snotty
nose; one who hurt it, being checked by the negro that took care of it,
told the slave he was very fond of his country-woman, and asked him
if he should not like her for a wife? To which the slave very readily
replied, 'No, this no my wife; this a white woman--this fit wife for
you.' This unlucky wit of the negro's, I fancy, hastened its death, for
next morning it was found dead under the windlass."
William Smith's 'Mandrill,' or 'Boggoe,' as his description and figure
testify, was, without doubt, a Chimpanzee.
(FIGURE 6.--The Anthropomorpha of Linnaeus.)
Linnaeus knew nothing, of his own observation, of the man-like Apes of
either Africa or Asia, but a dissertation by his pupil Hoppius in the
'Amoenitates Academicae' (VI. 'Anthropomorpha') may be regarded as
embodying his views respecting these animals.
The dissertation is illustrated by a plate, of which the accompanying
woodcut, Fig, 6, is a reduced copy, The figures are entitled (from left
to right) 1. 'Troglodyta Bontii'; 2. 'Lucifer Aldrovandi'; 3. 'Satyrus
Tulpii'; 4. 'Pygmaeus Edwardi'. The first is a bad copy of Bontius'
fictitious 'Ourang-outang,' in whose existence, however, Linnaeus
appears to have fully believed; for in the standard edition of the
'Systema Naturae', it is enumerated as a second species of Homo; "H.
nocturnus." 'Lucifer Aldrovandi' is a copy of a figure in Aldrovandus,
'De Quadrupedibus digitatis viviparis', Lib. 2, p. 249 (1645), entitled
"Cercopithecus formae rarae 'Barbilius' vocatus et originem a china
ducebat." Hoppius is of opinion that this may be one of that cat-tailed
people, of whom Nicolaus Koping affirms that they eat a boat's crew,
"gubernator navis" and all! In the 'Systema Naturae' Linnaeus calls it
in a note, 'Homo caudatus', and seems inclined to regard it as a third
species of man. According to Temminck, 'Satyrus Tulpii' is a copy of
the figure of a Chimpanzee published by Scotin in 1738, which I have
not seen. It is the 'Satyrus indicus' of the 'Systema Naturae', and
is regarded by Linnaeus as possibly a distinct species from 'Satyrus
sylvestris'. The last, named 'Pygmaeus Edwardi', is copied from the
figure of a young "Man of the Woods," or true Orang-Utan, given in
Edwards' 'Gleanings of Natural History' (1758).
Buffon was more fortunate than his great rival. Not only had he the rare
opportunity of examining a young Chimpanzee in the living state, but
he became possessed of an adult Asiatic man-like Ape--the first and the
last adult specimen of any of these animals brought to Europe for
many years. With the valuable assistance of Daubenton, Buffon gave
an excellent description of this creature, which, from its singular
proportions, he termed the long-armed Ape, or Gibbon. It is the modern
'Hylobates lar'.
Thus when, in 1766, Buffon wrote the fourteenth volume of his great
work, he was personally familiar with the young of one kind of African
man-like Ape, and with the adult of an Asiatic species--while the
Orang-Utan and the Mandrill of Smith were known to him by report.
Furthermore, the Abbe Prevost had translated a good deal of Purchas'
Pilgrims into French, in his 'Histoire generale des Voyages' (1748), and
there Buffon found a version of Andrew Battell's account of the Pongo
and the Engeco. All these data Buffon attempts to weld together into
harmony in his chapter entitled "Les Orang-outangs ou le Pongo et le
Jocko." To this title the following note is appended:--
"Orang-outang nom de cet animal aux Indes orientales: Pongo nom de cet
animal a Lowando Province de Congo.
"Jocko, Enjocko, nom de cet animal a Congo que nous avons adopte. 'En'
est l'article que nous avons retranche."
Thus it was that Andrew Battell's "Engeco" became metamorphosed into
"Jocko," and, in the latter shape, was spread all over the world, in
consequence of the extensive popularity of Buffon's works. The
Abbe Prevost and Buffon between them, however, did a good deal more
disfigurement to Battell's sober account than 'cutting off an article.'
Thus Battell's statement that the Pongos "cannot speake, and have no
understanding more than a beast," is rendered by Buffon "qu'il ne peut
parler 'quoiqu'il ait plus d'entendement que les autres animaux'"; and
again, Purchas' affirmation, "He told me in conference with him, that
one of these Pongos tooke a negro boy of his which lived a moneth with
them," stands in the French version, "un pongo lui enleva un petit negre
qui passa un 'an' entier dans la societe de ces animaux."
After quoting the account of the great Pongo, Buffon justly remarks,
that all the 'Jockos' and 'Orangs' hitherto brought to Europe were
young; and he suggests that, in their adult condition, they might be as
big as the Pongo or 'great Orang'; so that, provisionally, he regarded
the Jockos, Orangs, and Pongos as all of one species. And perhaps this
was as much as the state of knowledge at the time warranted. But how
it came about that Buffon failed to perceive the similarity of Smith's
'Mandrill' to his own 'Jocko,' and confounded the former with so
totally different a creature as the blue-faced Baboon, is not so easily
intelligible.
Twenty years later Buffon changed his opinion,* and expressed his belief
that the Orangs constituted a genus with two species,--a large one, the
Pongo of Battell, and a small one, the Jocko: that the small one (Jocko)
is the East Indian Orang; and that the young animals from Africa,
observed by himself and Tulpius, are simply young Pongos. ([Footnote]
*'Histoire Naturelle', Suppl. tome 7eme, 1789.)
In the meanwhile, the Dutch naturalist, Vosmaer, gave, in 1778, a very
good account and figure of a young Orang, brought alive to Holland, and
his countryman, the famous anatomist, Peter Camper, published (1779)
an essay on the Orang-Utan of similar value to that of Tyson on the
Chimpanzee. He dissected several females and a male, all of which, from
the state of their skeleton and their dentition, he justly supposes to
have been young. However, judging by the analogy of man, he concludes
that they could not have exceeded four feet in height in the adult
condition. Furthermore, he is very clear as to the specific distinctness
of the true East Indian Orang.
"The Orang," says he, "differs not only from the Pigmy of Tyson and from
the Orang of Tulpius by its peculiar colour and its long toes, but
also by its whole external form. Its arms, its hands, and its feet are
longer, while the thumbs, on the contrary, are much shorter, and the
great toes much smaller in proportion."* ([Footnote] *Camper, 'Oeuvres',
i. p. 56.) And again, "The true Orang, that is to say, that of Asia,
that of Borneo, is consequently not the Pithecus, or tailless Ape, which
the Greeks, and especially Galen, have described. It is neither
the Pongo nor the Jocko, nor the Orang of Tulpius, nor the Pigmy of
Tyson,--IT IS AN ANIMAL OF A PECULIAR SPECIES, as I shall prove in the
clearest manner by the organs of voice and the skeleton in the following
chapters" (l. c. p. 64).
A few years later, M. Radermacher, who held a high office in the
Government of the Dutch dominions in India, and was an active member of
the Batavian Society of Arts and Sciences, published, in the second part
of the Transactions of that Society,* a Description of the Island of
Borneo, which was written between the years 1779 and 1781, and, among
much other interesting matter, contains some notes upon the Orang.
([Footnote] *Verhandelingen van het Bataviaasch Genootschap. Tweede
Deel. Derde Druk. 1826. The small sort of Orang-Utan, viz. that of
Vosmaer and of Edwards, he says, is found only in Borneo, and chiefly
about Banjermassing, Mampauwa, and Landak. Of these he had seen some
fifty during his residence in the Indies; but none exceeded 2 1/2 feet
in length. The larger sort, often regarded as a chimera, continues
Radermacher, would perhaps long have remained so, had it not been for
the exertions of the Resident at Rembang, M. Palm, who, on returning
from Landak towards Pontiana, shot one, and forwarded it to Batavia in
spirit, for transmission to Europe.
Palm's letter describing the capture runs thus:--"Herewith I send your
Excellency, contrary to all expectation (since long ago I offered more
than a hundred ducats to the natives for an Orang-Utan of four or five
feet high) an Orang which I heard of this morning about eight o'clock.
For a long time we did our best to take the frightful beast alive in the
dense forest about half way to Landak. We forgot even to eat, so anxious
were we not to let him escape; but it was necessary to take care that
he did not revenge himself, as he kept continually breaking off heavy
pieces of wood and green branches, and dashing them at us. This game
lasted till four o'clock in the afternoon, when we determined to shoot
him; in which I succeeded very well, and indeed better than I ever shot
from a boat before; for the bullet went just into the side of his chest,
so that he was not much damaged. We got him into the prow still living,
and bound him fast, and next morning he died of his wounds. All Pontiana
came on board to see him when we arrived." Palm gives his height from
the head to the heel as 49 inches.
(FIGURE 7.--The Pongo Skull, sent by Radermacher to Camper, after
Camper's original sketches, as reproduced by Lucae.)
A very intelligent German officer, Baron Von Wurmb, who at this time
held a post in the Dutch East India service, and was Secretary of the
Batavian Society, studied this animal, and his careful description of
it, entitled "Beschrijving van der Groote Borneosche Orang-outang of de
Oost-Indische Pongo," is contained in the same volume of the Batavian
Society's Transactions. After Von Wurmb had drawn up his description he
states, in a letter dated Batavia, Feb. 18, 1781,* ([Footnote] *"Briefe
des Herrn v. Wurmb und des H. Baron von Wollzogen. Gotha, 1794." that
the specimen was sent to Europe in brandy to be placed in the collection
of the Prince of Orange; "unfortunately," he continues, "we hear that
the ship has been wrecked." Von Wurmb died in the course of the year
1781, the letter in which this passage occurs being the last he wrote;
but in his posthumous papers, published in the fourth part of the
Transactions of the Batavian Society, there is a brief description, with
measurements, of a female Pongo four feet high.
Did either of these original specimens, on which Von Wurmb's
descriptions are based, ever reach Europe? It is commonly supposed
that they did; but I doubt the fact. For, appended to the memoir 'De
l'Ourang-outang,' in the collected edition of Camper's works, tome i.,
pp. 64-66, is a note by Camper himself, referring to Von Wurmb's papers,
and continuing thus:--"Heretofore, this kind of ape had never been known
in Europe. Radermacher has had the kindness to send me the skull of one
of these animals, which measured fifty-three inches, or four feet five
inches, in height. I have sent some sketches of it to M. Soemmering at
Mayence, which are better calculated, however, to give an idea of the
form than of the real size of the parts."
These sketches have been reproduced by Fischer and by Lucae, and bear
date 1783, Soemmering having received them in 1784. Had either of Von
Wurmb's specimens reached Holland, they would hardly have been unknown
at this time to Camper, who, however, goes on to say--"It appears that
since this, some more of these monsters have been captured, for an
entire skeleton, very badly set up, which had been sent to the Museum
of the Prince of Orange, and which I saw only on the 27th of June, 1784,
was more than four feet high. I examined this skeleton again on the
19th December, 1785, after it had been excellently put to rights by the
ingenious Onymus."
It appears evident, then, that this skeleton, which is doubtless that
which has always gone by the name of Wurmb's Pongo, is not that of the
animal described by him, though unquestionably similar in all essential
points.
Camper proceeds to note some of the most important features of this
skeleton; promises to describe it in detail by-and-bye; and is evidently
in doubt as to the relation of this great 'Pongo' to his "petit Orang."
The promised further investigations were never carried out; and so it
happened that the Pongo of Von Wurmb took its place by the side of
the Chimpanzee, Gibbon, and Orang as a fourth and colossal species
of man-like Ape. And indeed nothing could look much less like the
Chimpanzees or the Orangs, then known, than the Pongo; for all the
specimens of Chimpanzee and Orang which had been observed were small of
stature, singularly human in aspect, gentle and docile; while Wurmb's
Pongo was a monster almost twice their size, of vast strength and
fierceness, and very brutal in expression; its great projecting muzzle,
armed with strong teeth, being further disfigured by the outgrowth of
the cheeks into fleshy lobes.
Eventually, in accordance with the usual marauding habits of the
Revolutionary armies, the 'Pongo' skeleton was carried away from Holland
into France, and notices of it, expressly intended to demonstrate its
entire distinctness from the Orang and its affinity with the baboons,
were given, in 1798, by Geoffroy St. Hilaire and Cuvier.
Even in Cuvier's 'Tableau Elementaire', and in the first edition of his
great work, the 'Regne Animal', the 'Pongo' is classed as a species of
Baboon. However, so early as 1818, it appears that Cuvier saw reason to
alter this opinion, and to adopt the view suggested several years before
by Blumenbach,* and after him by Tilesius, that the Bornean Pongo
is simply an adult Orang. ([Footnote] *See Blumenbach, 'Abbildungen
Naturhistorichen Gegenstande', No. 12, 1810; and Tilesius,
'Naturhistoriche Fruchte der ersten Kaiserlich-Russischen
Erdumsegelung', p. 115, 1813.) In 1824, Rudolphi demonstrated, by the
condition of the dentition, more fully and completely than had been done
by his predecessors, that the Orangs described up to that time were all
young animals, and that the skull and teeth of the adult would probably
be such as those seen in the Pongo of Wurmb. In the second edition of
the 'Regne Animal' (1829), Cuvier infers, from the 'proportions of all
the parts' and 'the arrangements of the foramina and sutures of the
head,' that the Pongo is the adult of the Orang-Utan, 'at least of a
very closely allied species,' and this conclusion was eventually placed
beyond all doubt by Professor Owen's Memoir published in the 'Zoological
Transactions' for 1835, and by Temminck in his 'Monographies de
Mammalogie'. Temminck's memoir is remarkable for the completeness of the
evidence which it affords as to the modification which the form of the
Orang undergoes according to age and sex. Tiedemann first published an
account of the brain of the young Orang, while Sandifort, Muller and
Schlegel, described the muscles and the viscera of the adult, and gave
the earliest detailed and trustworthy history of the habits of the great
Indian Ape in a state of nature; and as important additions have been
made by later observers, we are at this moment better acquainted with
the adult of the Orang-Utan, than with that of any of the other greater
man-like Apes.
It is certainly the Pongo of Wurmb;* and it is as certainly not the
Pongo of Battell, seeing that the Orang-Utan is entirely confined to
the great Asiatic islands of Borneo and Sumatra. ([Footnote] *Speaking
broadly and without prejudice to the question, whether there be more
than one species of Orang.)
And while the progress of discovery thus cleared up the history of the
Orang, it also became established that the only other man-like Apes in
the eastern world were the various species of Gibbon--Apes of smaller
stature, and therefore attracting less attention than the Orangs, though
they are spread over a much wider range of country, and are hence more
accessible to observation.
Although the geographical area inhabited by the 'Pongo' and Engeco of
Battell is so much nearer to Europe than that in which the Orang and
Gibbon are found, our acquaintance with the African Apes has been of
slower growth; indeed, it is only within the last few years that the
truthful story of the old English adventurer has been rendered fully
intelligible. It was not until 1835 that the skeleton of the adult
Chimpanzee became known, by the publication of Professor Owen's
above-mentioned very excellent memoir 'On the osteology of the
Chimpanzee and Orang', in the 'Zoological Transactions'--a memoir which,
by the accuracy of its descriptions, the carefulness of its comparisons,
and the excellence of its figures, made an epoch in the history of our
knowledge of the bony framework, not only of the Chimpanzee, but of all
the anthropoid Apes.
By the investigations herein detailed, it became evident that the old
Chimpanzee acquired a size and aspect as different from those of the
young known to Tyson, to Buffon, and to Traill, as those of the old
Orang from the young Orang; and the subsequent very important researches
of Messrs. Savage and Wyman, the American missionary and anatomist, have
not only confirmed this conclusion, but have added many new details.*
([Footnote] *See "Observations on the external characters and habits
of the Troglodytes niger, by Thomas N. Savage, M.D., and on its
organization by Jeffries Wyman, M.D.," 'Boston Journal of Natural
History', vol. iv., 1843-4; and "External characters, habits, and
osteology of Troglodytes Gorilla," by the same authors, 'ibid'., vol.
v., 1847.)
One of the most interesting among the many valuable discoveries made by
Dr. Thomas Savage is the fact, that the natives in the Gaboon country at
the present day, apply to the Chimpanzee a name--"Enche-eko"--which is
obviously identical with the "Engeko" of Battell; a discovery which has
been confirmed by all later inquirers. Battell's "lesser monster" being
thus proved to be a veritable existence, of course a strong presumption
arose that his "greater monster," the 'Pongo,' would sooner or later
be discovered. And, indeed, a modern traveller, Bowdich, had, in 1819,
found strong evidence, among the natives, of the existence of a second
great Ape, called the 'Ingena,' "five feet high, and four across the
shoulders," the builder of a rude house, on the outside of which it
slept.
In 1847, Dr. Savage had the good fortune to make another and most
important addition to our knowledge of the man-like Apes; for, being
unexpectedly detained at the Gaboon river, he saw in the house of the
Rev. Mr. Wilson, a missionary resident there, "a skull represented
by the natives to be a monkey-like animal, remarkable for its
size, ferocity, and habits." From the contour of the skull, and the
information derived from several intelligent natives, "I was induced,"
says Dr. Savage (using the term Orang in its old general sense) "to
believe that it belonged to a new species of Orang. I expressed this
opinion to Mr. Wilson, with a desire for further investigation; and, if
possible, to decide the point by the inspection of a specimen alive or
dead." The result of the combined exertions of Messrs. Savage and Wilson
was not only the obtaining of a very full account of the habits of
this new creature, but a still more important service to science, the
enabling the excellent American anatomist already mentioned, Professor
Wyman, to describe, from ample materials, the distinctive osteological
characters of the new form. This animal was called by the natives of
the Gaboon "Enge-ena," a name obviously identical with the "Ingena"
of Bowdich; and Dr. Savage arrived at the conviction that this last
discovered of all the great Apes was the long-sought "Pongo" of Battell.
The justice of this conclusion, indeed, is beyond doubt--for not only
does the 'Enge-ena' agree with Battell's "greater monster" in its hollow
eyes, its great stature, and its dun or iron-grey colour, but the only
other man-like Ape which inhabits these latitudes--the Chimpanzee--is
at once identified, by its smaller size, as the "lesser monster," and is
excluded from any possibility of being the 'Pongo,' by the fact that
it is black and not dun, to say nothing of the important circumstance
already mentioned that it still retains the name of 'Engeko,' or
"Enche-eko," by which Battell knew it.
In seeking for a specific name for the "Enge-ena," however, Dr. Savage
wisely avoided the much misused 'Pongo'; but finding in the ancient
Periplus of Hanno the word "Gorilla" applied to certain hairy savage
people, discovered by the Carthaginian voyager in an island on the
African coast, he attached the specific name "Gorilla" to his new ape,
whence arises its present well-known appellation. But Dr. Savage, more
cautious than some of his successors, by no means identifies his ape
with Hanno's "wild men." He merely says that the latter were "probably
one of the species of the Orang;" and I quite agree with M. Brulle, that
there is no ground for identifying the modern 'Gorilla' with that of the
Carthaginian admiral.
Since the memoir of Savage and Wyman was published, the skeleton of
the Gorilla has been investigated by Professor Owen and by the late
Professor Duvernoy, of the Jardin des Plantes, the latter having further
supplied a valuable account of the muscular system and of many of
the other soft parts; while African missionaries and travellers have
confirmed and expanded the account originally given of the habits of
this great man-like Ape, which has had the singular fortune of being
the first to be made known to the general world and the last to be
scientifically investigated.
Two centuries and a half have passed away since Battell told his stories
about the 'greater' and the 'lesser monsters' to Purchas, and it has
taken nearly that time to arrive at the clear result that there are
four distinct kinds of Anthropoids--in Eastern Asia, the Gibbons and the
Orangs; in Western Africa, the Chimpanzees and the Gorilla.
The man-like Apes, the history of whose discovery has just been
detailed, have certain characters of structure and of distribution in
common. Thus they all have the same number of teeth as man--possessing
four incisors, two canines, four false molars, and six true molars in
each jaw, or 32 teeth in all, in the adult condition; while the milk
dentition consists of 20 teeth--or four incisors, two canines, and four
molars in each jaw. They are what are called catarrhine Apes--that
is, their nostrils have a narrow partition and look downwards;
and, furthermore, their arms are always longer than their legs, the
difference being sometimes greater and sometimes less; so that if
the four were arranged in the order of the length of their arms in
proportion to that of their legs, we should have this series--Orang (1
4/9: 1), Gibbon (1 1/4: 1), Gorilla (1 1/5: 1), Chimpanzee (1 1/16: 1).
In all, the fore limbs are terminated by hands, provided with longer or
shorter thumbs; while the great toe of the foot, always smaller than in
Man, is far more movable than in him and can be opposed, like a thumb,
to the rest of the foot. None of these apes have tails, and none of them
possess the cheek pouches common among monkeys. Finally, they are all
inhabitants of the old world.
The Gibbons are the smallest, slenderest, and longest-limbed of the
man-like apes: their arms are longer in proportion to their bodies than
those of any of the other man-like Apes, so that they can touch the
ground when erect; their hands are longer than their feet, and they are
the only Anthropoids which possess callosities like the lower monkeys.
They are variously coloured. The Orangs have arms which reach to the
ankles in the erect position of the animal; their thumbs and great toes
are very short, and their feet are longer than their hands. They are
covered with reddish brown hair, and the sides of the face, in adult
males, are commonly produced into two crescentic, flexible excrescences,
like fatty tumours. The Chimpanzees have arms which reach below the
knees; they have large thumbs and great toes, their hands are longer
than their feet; and their hair is black, while the skin of the face
is pale. The Gorilla, lastly, has arms which reach to the middle of the
leg, large thumbs and great toes, feet longer than the hands, a black
face, and dark-grey or dun hair.
For the purpose which I have at present in view, it is unnecessary that
I should enter into any further minutiae respecting the distinctive
characters of the genera and species into which these man-like Apes
are divided by naturalists. Suffice it to say, that the Orangs and the
Gibbons constitute the distinct genera, 'Simia' and 'Hylobates'; while
the Chimpanzees and Gorillas are by some regarded simply as
distinct species of one genus, 'Troglodytes'; by others as distinct
genera--'Troglodytes' being reserved for the Chimpanzees, and 'Gorilla'
for the Enge-ena or Pongo.
Sound knowledge respecting the habits and mode of life of the man-like
Apes has been even more difficult of attainment than correct information
regarding their structure.
Once in a generation, a Wallace may be found physically, mentally, and
morally qualified to wander unscathed through the tropical wilds of
America and of Asia; to form magnificent collections as he wanders;
and withal to think out sagaciously the conclusions suggested by his
collections: but, to the ordinary explorer or collector, the dense
forests of equatorial Asia and Africa, which constitute the favourite
habitation of the Orang, the Chimpanzee, and the Gorilla, present
difficulties of no ordinary magnitude: and the man who risks his life by
even a short visit to the malarious shores of those regions may well
be excused if he shrinks from facing the dangers of the interior; if he
contents himself with stimulating the industry of the better seasoned
natives, and collecting and collating the more or less mythical reports
and traditions with which they are too ready to supply him.
In such a manner most of the earlier accounts of the habits of the
man-like Apes originated; and even now a good deal of what passes
current must be admitted to have no very safe foundation. The best
information we possess is that, based almost wholly on direct European
testimony respecting the Gibbons; the next best evidence relates to
the Orangs; while our knowledge of the habits of the Chimpanzee and the
Gorilla stands much in need of support and enlargement by additional
testimony from instructed European eye-witnesses.
It will therefore be convenient in endeavouring to form a notion of what
we are justified in believing about these animals, to commence with the
best known man-like Apes, the Gibbons and Orangs; and to make use of the
perfectly reliable information respecting them as a sort of criterion of
the probable truth or falsehood of assertions respecting the others.
Of the GIBBONS, half a dozen species are found scattered over the
Asiatic islands, Java, Sumatra, Borneo, and through Malacca, Siam,
Arracan, and an uncertain extent of Hindostan, on the main land of Asia.
The largest attain a few inches above three feet in height, from the
crown to the heel, so that they are shorter than the other man-like
Apes; while the slenderness of their bodies renders their mass far
smaller in proportion even to this diminished height.
Dr. Salomon Muller, an accomplished Dutch naturalist, who lived for many
years in the Eastern Archipelago, and to the results of whose personal
experience I shall frequently have occasion to refer, states that the
Gibbons are true mountaineers, loving the slopes and edges of the hills,
though they rarely ascend beyond the limit of the fig-trees. All day
long they haunt the tops of the tall trees; and though, towards evening,
they descend in small troops to the open ground, no sooner do they spy
a man than they dart up the hill-sides, and disappear in the darker
valleys.
All observers testify to the prodigious volume of voice possessed by
these animals. According to the writer whom I have just cited, in one of
them, the Siamang, "the voice is grave and penetrating, resembling the
sounds goek, goek, goek, goek, goek ha ha ha ha haaaaa, and may easily
be heard at a distance of half a league." While the cry is being
uttered, the great membranous bag under the throat which communicates
with the organ of voice, the so-called "laryngeal sac," becomes greatly
distended, diminishing again when the creature relapses into silence.
M. Duvaucel, likewise, affirms that the cry of the Siamang may be heard
for miles--making the woods ring again. So Mr. Martin* describes the cry
of the agile Gibbon as "overpowering and deafening" in a room, and "from
its strength, well calculated for resounding through the vast forests."
([Footnote] *'Man and Monkies', p. 423.) Mr. Waterhouse, an accomplished
musician as well as zoologist, says, "The Gibbon's voice is certainly
much more powerful than that of any singer I have ever heard." And yet
it is to be recollected that this animal is not half the height of, and
far less bulky in proportion than, a man.
There is good testimony that various species of Gibbon readily take to
the erect posture. Mr. George Bennett,* a very excellent observer, in
describing the habits of a male 'Hylobates syndactylus' which remained
for some time in his possession, says: "He invariably walks in the erect
posture when on a level surface; and then the arms either hang down,
enabling him to assist himself with his knuckles; or what is more usual,
he keeps his arms uplifted in nearly an erect position, with the hands
pendent ready to seize a rope, and climb up on the approach of danger
or on the obtrusion of strangers. He walks rather quick in the erect
posture, but with a waddling gait, and is soon run down if, whilst
pursued, he has no opportunity of escaping by climbing...When he walks
in the erect posture he turns the leg and foot outwards, which occasions
him to have a waddling gait and to seem bow-legged." ([Footnote]
*'Wanderings in New South Wales', vol. ii. chap. viii., 1834.)
Dr. Burrough states of another Gibbon, the Horlack or Hooluk: "They
walk erect; and when placed on the floor, or in an open field, balance
themselves very prettily, by raising their hands over their head and
slightly bending the arm at the wrist and elbow, and then run tolerably
fast, rocking from side to side; and, if urged to greater speed, they
let fall their hands to the ground, and assist themselves forward,
rather jumping than running, still keeping the body, however, nearly
erect."
Somewhat different evidence, however, is given by Dr. Winslow Lewis:*
([Footnote] *'Boston Journal of Natural History', vol. i., 1834.)
"Their only manner of walking was on their posterior or inferior
extremities, the others being raised upwards to preserve their
equilibrium, as rope-dancers are assisted by long poles at fairs.
Their progression was not by placing one foot before the other, but
by simultaneously using both, as in jumping." Dr. Salomon Muller also
states that the Gibbons progress along the ground by a short series of
tottering jumps, effected only by the hind limbs, the body being held
altogether upright.
But Mr. Martin (l. c. p. 418), who also speaks from direct observation,
says of the Gibbons generally:
"Pre-eminently qualified for arboreal habits, and displaying among the
branches amazing activity, the Gibbons are not so awkward or embarrassed
on a level surface as might be imagined. They walk erect, with a
waddling or unsteady gait, but at a quick pace; the equilibrium of the
body requiring to be kept up, either by touching the ground with the
knuckles, first on one side then on the other, or by uplifting the arms
so as to poise it. As with the Chimpanzee, the whole of the narrow, long
sole of the foot is placed upon the ground at once and raised at once,
without any elasticity of step."
(FIGURE 8.--Gibbon ('H. pileatus'), after Wolf.)
After this mass of concurrent and independent testimony, it cannot
reasonably be doubted that the Gibbons commonly and habitually assume
the erect attitude.
But level ground is not the place where these animals can display their
very remarkable and peculiar locomotive powers, and that prodigious
activity which almost tempts one to rank them among flying, rather than
among ordinary climbing mammals.
Mr. Martin (l.c. p. 430) has given so excellent and graphic an account
of the movements of a 'Hylobates agilis', living in the Zoological
Gardens, in 1840, that I will quote it in full:
"It is almost impossible to convey in words an idea of the quickness and
graceful address of her movements: they may indeed be termed aerial, as
she seems merely to touch in her progress the branches among which she
exhibits her evolutions. In these feats her hands and arms are the
sole organs of locomotion; her body hanging as if suspended by a rope,
sustained by one hand (the right for example) she launches herself, by
an energetic movement, to a distant branch, which she catches with the
left hand; but her hold is less than momentary: the impulse for the next
launch is acquired: the branch then aimed at is attained by the right
hand again, and quitted instantaneously, and so on, in alternate
succession. In this manner spaces of twelve and eighteen feet are
cleared, with the greatest ease and uninterruptedly, for hours together,
without the slightest appearance of fatigue being manifested; and it
is evident that, if more space could be allowed, distances very greatly
exceeding eighteen feet would be as easily cleared; so that Duvaucel's
assertion that he has seen these animals launch themselves from one
branch to another, forty feet asunder, startling as it is, may be well
credited. Sometimes, on seizing a branch in her progress, she will throw
herself, by the power of one arm only, completely round it, making a
revolution with such rapidity as almost to deceive the eye, and continue
her progress with undiminished velocity. It is singular to observe how
suddenly this Gibbon can stop, when the impetus given by the rapidity
and distance of her swinging leaps would seem to require a gradual
abatement of her movements. In the very midst of her flight a branch is
seized, the body raised, and she is seen, as if by magic, quietly seated
on it, grasping it with her feet. As suddenly she again throws herself
into action.
"The following facts will convey some notion of her dexterity and
quickness. A live bird was let loose in her apartment; she marked its
flight, made a long swing to a distant branch, caught the bird with one
hand in her passage, and attained the branch with her other hand; her
aim, both at the bird and at the branch, being as successful as if
one object only had engaged her attention. It may be added that she
instantly bit off the head of the bird, picked its feathers, and then
threw it down without attempting to eat it.
"On another occasion this animal swung herself from a perch, across a
passage at least twelve feet wide, against a window which it was thought
would be immediately broken: but not so; to the surprise of all, she
caught the narrow framework between the panes with her hand, in an
instant attained the proper impetus, and sprang back again to the cage
she had left--a feat requiring not only great strength, but the nicest
precision."
The Gibbons appear to be naturally very gentle, but there is very
good evidence that they will bite severely when irritated--a female
'Hylobates agilis' having so severely lacerated one man with her long
canines, that he died; while she had injured others so much that, by
way of precaution, these formidable teeth had been filed down; but, if
threatened, she would still turn on her keeper. The Gibbons eat insects,
but appear generally to avoid animal food. A Siamang, however, was seen
by Mr. Bennett to seize and devour greedily a live lizard. They commonly
drink by dipping their fingers in the liquid and then licking them. It
is asserted that they sleep in a sitting posture.
Duvaucel affirms that he has seen the females carry their young to the
waterside and there wash their faces, in spite of resistance and cries.
They are gentle and affectionate in captivity--full of tricks and
pettishness, like spoiled children, and yet not devoid of a certain
conscience, as an anecdote, told by Mr. Bennett (l. c. p. 156), will
show. It would appear that his Gibbon had a peculiar inclination for
disarranging things in the cabin. Among these articles, a piece of soap
would especially attract his notice, and for the removal of this he
had been once or twice scolded. "One morning," says Mr. Bennett, "I
was writing, the ape being present in the cabin, when casting my eyes
towards him, I saw the little fellow taking the soap. I watched him
without his perceiving that I did so: and he occasionally would cast a
furtive glance towards the place where I sat. I pretended to write; he,
seeing me busily occupied, took the soap, and moved away with it in his
paw. When he had walked half the length of the cabin, I spoke quietly,
without frightening him. The instant he found I saw him, he walked back
again, and deposited the soap nearly in the same place from whence he
had taken it. There was certainly something more than instinct in that
action: he evidently betrayed a consciousness of having done wrong both
by his first and last actions--and what is reason if that is not an
exercise of it?"
The most elaborate account of the natural history of the ORANG-UTAN
extant, is that given in the "Verhandelingen over de Natuurlijke
Geschiedenis der Nederlandsche overzeesche Bezittingen (1839-45)," by
Dr. Salomon Muller and Dr. Schlegel, and I shall base what I have to
say, upon this subject almost entirely on their statements, adding, here
and there, particulars of interest from the writings of Brooke, Wallace,
and others.
The Orang-Utan would rarely seem to exceed four feet in height, but
the body is very bulky, measuring two-thirds of the height in
circumference.* ([Footnote] *The largest Orang-Utan, cited by Temminck,
measured, when standing upright, 4 ft.; but he mentions having just
received news of the capture of an Orang 5 ft. 3 in. high. Schlegel
and Muller say that their largest old male measured, upright, 1.25
Netherlands "el"; and from the crown to the end of the toes, 1.5 el; the
circumference of the body being about 1 el. The largest old female
was 1.09 el high, when standing. The adult skeleton in the College of
Surgeons' Museum, if set upright, would stand 3 ft. 6-8 in. from crown
to sole. Dr. Humphry gives 3 ft. 8 in. as the mean height of two Orangs.
Of seventeen Orangs examined by Mr. Wallace, the largest was 4 ft. 2
in. high, from the heel to the crown of the head. Mr. Spencer St. John,
however, in his 'Life in the Forests of the Far East', tells us of an
Orang of "5 ft. 2 in., measuring fairly from the head to the heel," 15
in. across the face, and 12 in. round the wrist. It does not appear,
however, that Mr. St. John measured this Orang himself.)
The Orang-Utan is found only in Sumatra and Borneo, and is common in
neither of these islands--in both of which it occurs always in low, flat
plains, never in the mountains. It loves the densest and most sombre of
the forests, which extend from the sea-shore inland, and thus is found
only in the eastern half of Sumatra, where alone such forests occur,
though, occasionally, it strays over to the western side.
On the other hand, it is generally distributed through Borneo, except in
the mountains, or where the population is dense. In favourable places,
the hunter may, by good fortune, see three or four in a day.
(FIGURE 9.--An adult male Orang-utan, after Muller and Schlegel.)
Except in the pairing time, the old males usually live by themselves.
The old females, and the immature males, on the other hand, are often
met with in twos and threes; and the former occasionally have young
with them, though the pregnant females usually separate themselves, and
sometimes remain apart after they have given birth to their offspring.
The young Orangs seem to remain unusually long under their mother's
protection, probably in consequence of their slow growth. While
climbing, the mother always carries her young against her bosom, the
young holding on by his mother's hair.* ([Footnote] *See Mr. Wallace's
account of an infant "Orang-utan," in the 'Annals of Natural History'
for 1856. Mr. Wallace provided his interesting charge with an artificial
mother of buffalo-skin, but the cheat was too successful. The infant's
entire experience led it to associate teats with hair, and feeling
the latter, it spent its existence in vain endeavours to discover
the former.) At what time of life the Orang-Utan becomes capable of
propagation, and how long the females go with young, is unknown, but it
is probable that they are not adult until they arrive at ten or fifteen
years of age. A female which lived for five years at Batavia, had not
attained one-third the height of the wild females. It is probable that,
after reaching adult years, they go on growing, though slowly, and that
they live to forty or fifty years. The Dyaks tell of old Orangs, which
have not only lost all their teeth, but which find it so troublesome to
climb, that they maintain themselves on windfalls and juicy herbage.
The Orang is sluggish, exhibiting none of that marvellous activity
characteristic of the Gibbons. Hunger alone seems to stir him to
exertion, and when it is stilled, he relapses into repose. When the
animal sits, it curves its back and bows its head, so as to look
straight down on the ground; sometimes it holds on with its hands by
a higher branch, sometimes lets them hang phlegmatically down by its
side--and in these positions the Orang will remain, for hours together,
in the same spot, almost without stirring, and only now and then giving
utterance to its deep, growling voice. By day, he usually climbs from
one tree-top to another, and only at night descends to the ground, and
if then threatened with danger, he seeks refuge among the underwood.
When not hunted, he remains a long time in the same locality, and
sometimes stops for many days on the same tree--a firm place among its
branches serving him for a bed. It is rare for the Orang to pass the
night in the summit of a large tree, probably because it is too windy
and cold there for him; but, as soon as night draws on, he descends from
the height and seeks out a fit bed in the lower and darker part, or
in the leafy top of a small tree, among which he prefers Nibong Palms,
Pandani, or one of those parasitic Orchids which give the primeval
forests of Borneo so characteristic and striking an appearance. But
wherever he determines to sleep, there he prepares himself a sort of
nest: little boughs and leaves are drawn together round the selected
spot, and bent crosswise over one another; while to make the bed soft,
great leaves of Ferns, of Orchids, of 'Pandanus fascicularis', 'Nipa
fruticans', etc., are laid over them. Those which Muller saw, many of
them being very fresh, were situated at a height of ten to twenty-five
feet above the ground, and had a circumference, on the average, of
two or three feet. Some were packed many inches thick with 'Pandanus'
leaves; others were remarkable only for the cracked twigs, which, united
in a common centre, formed a regular platform. "The rude 'hut'," says
Sir James Brooke, "which they are stated to build in the trees, would be
more properly called a seat or nest, for it has no roof or cover of any
sort. The facility with which they form this nest is curious, and I had
an opportunity of seeing a wounded female weave the branches together
and seat herself, within a minute."
According to the Dyaks, the Orang rarely leaves his bed before the sun
is well above the horizon and has dissipated the mists. He gets up about
nine, and goes to bed again about five; but sometimes not till late in
the twilight. He lies sometimes on his back; or, by way of change, turns
on one side or the other, drawing his limbs up to his body, and resting
his head on his hand. When the night is cold, windy, or rainy, he
usually covers his body with a heap of 'Pandanus', 'Nipa', or Fern
leaves, like those of which his bed is made, and he is especially
careful to wrap up his head in them. It is this habit of covering
himself up which has probably led to the fable that the Orang builds
huts in the trees.
Although the Orang resides mostly amid the boughs of great trees, during
the daytime, he is very rarely seen squatting on a thick branch,
as other apes, and particularly the Gibbons, do. The Orang, on the
contrary, confines himself to the slender leafy branches, so that he
is seen right at the top of the trees, a mode of life which is closely
related to the constitution of his hinder limbs, and especially to
that of his seat. For this is provided with no callosities, such as are
possessed by many of the lower apes, and even by the Gibbons; and those
bones of the pelvis, which are termed the ischia, and which form the
solid framework of the surface on which the body rests in the sitting
posture, are not expanded like those of the apes which possess
callosities, but are more like those of man.
An Orang climbs so slowly and cautiously,* as, in this act, to resemble
a man more than an ape, taking great care of his feet, so that injury of
them seems to affect him far more than it does other apes. ([Footnote]
* "They are the slowest and least active of all the monkey tribe, and
their motions are surprisingly awkward and uncouth."--Sir James Brooke,
in the 'Proceedings of the Zoological Society', 1841.) Unlike the
Gibbons, whose forearms do the greater part of the work, as they swing
from branch to branch, the Orang never makes even the smallest jump. In
climbing, he moves alternately one hand and one foot, or, after having
laid fast hold with the hands, he draws up both feet together. In
passing from one tree to another, he always seeks out a place where
the twigs of both come close together, or interlace. Even when closely
pursued, his circumspection is amazing: he shakes the branches to see
if they will bear him, and then bending an overhanging bough down by
throwing his weight gradually along it, he makes a bridge from the tree
he wishes to quit to the next.* ([Footnote] *Mr. Wallace's account of
the progression of the Orang almost exactly corresponds with this.)
On the ground the Orang always goes laboriously and shakily, on all
fours. At starting he will run faster than a man, though he may soon be
overtaken. The very long arms which, when he runs, are but little bent,
raise the body of the Orang remarkably, so that he assumes much the
posture of a very old man bent down by age, and making his way along by
the help of a stick. In walking, the body is usually directed straight
forward, unlike the other apes, which run more or less obliquely;
except the Gibbons, who in these, as in so many other respects, depart
remarkably from their fellows.
The Orang cannot put its feet flat on the ground, but is supported upon
their outer edges, the heel resting more on the ground, while the curved
toes partly rest upon the ground by the upper side of their first joint,
the two outermost toes of each foot completely resting on this surface.
The hands are held in the opposite manner, their inner edges serving as
the chief support. The fingers are then bent out in such a manner that
their foremost joints, especially those of the two innermost fingers,
rest upon the ground by their upper sides, while the point of the free
and straight thumb serves as an additional fulcrum.
The Orang never stands on its hind legs, and all the pictures,
representing it as so doing, are as false as the assertion that it
defends itself with sticks, and the like.
The long arms are of especial use, not only in climbing, but in the
gathering of food from boughs to which the animal could not trust his
weight. Figs, blossoms, and young leaves of various kinds, constitute
the chief nutriment of the Orang; but strips of bamboo two or three
feet long were found in the stomach of a male. They are not known to eat
living animals.
Although, when taken young, the Orang-Utan soon becomes domesticated,
and indeed seems to court human society, it is naturally a very wild and
shy animal, though apparently sluggish and melancholy. The Dyaks
affirm, that when the old males are wounded with arrows only, they will
occasionally leave the trees and rush raging upon their enemies, whose
sole safety lies in instant flight, as they are sure to be killed if
caught.* ([Footnote] *Sir James Brooke, in a letter to Mr. Waterhouse,
published in the proceedings of the Zoological Society for 1841,
says:--"On the habits of the Orangs, as far as I have been able to
observe them, I may remark that they are as dull and slothful as can
well be conceived, and on no occasion, when pursuing them, did they
move so fast as to preclude my keeping pace with them easily through
a moderately clear forest; and even when obstructions below (such as
wading up to the neck) allowed them to get away some distance, they were
sure to stop and allow me to come up. I never observed the slightest
attempt at defence, and the wood which sometimes rattled about our ears
was broken by their weight, and not thrown, as some persons represent.
If pushed to extremity, however, the 'Pappan' could not be otherwise
than formidable, and one unfortunate man, who, with a party, was trying
to catch a large one alive, lost two of his fingers, besides being
severely bitten on the face, whilst the animal finally beat off his
pursuers and escaped." Mr. Wallace, on the other hand, affirms that he
has several times observed them throwing down branches when pursued.
"It is true he does not throw them 'at' a person, but casts them down
vertically; for it is evident that a bough cannot be thrown to any
distance from the top of a lofty tree. In one case a female Mias, on
a durian tree, kept up for at least ten minutes a continuous shower of
branches and of the heavy, spined fruits, as large as 32-pounders, which
most effectually kept us clear of the tree she was on. She could be seen
breaking them off and throwing them down with every appearance of
rage, uttering at intervals a loud pumping grunt, and evidently meaning
mischief."--"On the Habits of the Orang-Utan," 'Annals of Nat. History,
1856. This statement, it will be observed, is quite in accordance with
that contained in the letter of the Resident Palm quoted above (p.
210).)
But, though possessed of immense strength, it is rare for the Orang to
attempt to defend itself, especially when attacked with fire-arms. On
such occasions he endeavours to hide himself, or to escape along the
topmost branches of the trees, breaking off and throwing down the boughs
as he goes. When wounded he betakes himself to the highest attainable
point of the tree, and emits a singular cry, consisting at first of
high notes, which at length deepen into a low roar, not unlike that of a
panther. While giving out the high notes the Orang thrusts out his lips
into a funnel shape; but in uttering the low notes he holds his mouth
wide open, and at the same time the great throat bag, or laryngeal sac,
becomes distended.
According to the Dyaks, the only animal the Orang measures his strength
with is the crocodile, who occasionally seizes him on his visits to the
water side. But they say that the Orang is more than a match for his
enemy, and beats him to death, or rips up his throat by pulling the jaws
asunder!
Much of what has been here stated was probably derived by Dr. Muller
from the reports of his Dyak hunters; but a large male, four feet high,
lived in captivity, under his observation, for a month, and receives a
very bad character.
"He was a very wild beast," says Muller, "of prodigious strength, and
false and wicked to the last degree. If any one approached he rose up
slowly with a low growl, fixed his eyes in the direction in which he
meant to make his attack, slowly passed his hand between the bars of his
cage, and then extending his long arm, gave a sudden grip--usually at
the face." He never tried to bite (though Orangs will bite one another),
his great weapons of offence and defence being his hands.
His intelligence was very great; and Muller remarks, that though the
faculties of the Orang have been estimated too highly, yet Cuvier, had
he seen this specimen, would not have considered its intelligence to be
only a little higher than that of the dog.
His hearing was very acute, but the sense of vision seemed to be less
perfect. The under lip was the great organ of touch, and played a very
important part in drinking, being thrust out like a trough, so as
either to catch the falling rain, or to receive the contents of the half
cocoa-nut shell full of water with which the Orang was supplied, and
which, in drinking, he poured into the trough thus formed.
In Borneo the Orang-Utan of the Malays goes by the name of "Mias" among
the Dyaks, who distinguish several kinds as 'Mias Pappan', or 'Zimo',
'Mias Kassu', and 'Mias Rambi'. Whether these are distinct species,
however, or whether they are mere races, and how far any of them are
identical with the Sumatran Orang, as Mr. Wallace thinks the Mias Pappan
to be, are problems which are at present undecided; and the variability
of these great apes is so extensive, that the settlement of the question
is a matter of great difficulty. Of the form called "Mias Pappan," Mr.
Wallace* observes, ([Footnote] *On the Orang-Utan, or Mias of Borneo,
'Annals of Natural History', 1856.) "It is known by its large size,
and by the lateral expansion of the face into fatty protuberances,
or ridges, over the temporal muscles, which has been mis-termed
'callosities', as they are perfectly soft, smooth, and flexible. Five
of this form, measured by me, varied only from 4 feet 1 inch to 4 feet
2 inches in height, from the heel to the crown of the head, the girth
of the body from 3 feet to 3 feet 7 1/2 inches, and the extent of the
outstretched arms from 7 feet 2 inches to 7 feet 6 inches; the width
of the face from 10 to 13 1/4 inches. The colour and length of the hair
varied in different individuals, and in different parts of the same
individual; some possessed a rudimentary nail on the great toe, others
none at all; but they otherwise present no external differences on which
to establish even varieties of a species.
"Yet, when we examine the crania of these individuals, we find
remarkable differences of form, proportion, and dimension, no two being
exactly alike. The slope of the profile, and the projection of the
muzzle, together with the size of the cranium, offer differences as
decided as those existing between the most strongly marked forms of the
Caucasian and African crania in the human species. The orbits vary in
width and height, the cranial ridge is either single or double, either
much or little developed, and the zygomatic aperture varies considerably
in size. This variation in the proportions of the crania enables
us satisfactorily to explain the marked difference presented by the
single-crested and double-crested skulls, which have been thought to
prove the existence of two large species of Orang. The external surface
of the skull varies considerably in size, as do also the zygomatic
aperture and the temporal muscle; but they bear no necessary relation to
each other, a small muscle often existing with a large cranial surface,
and 'vice versa'. Now, those skulls which have the largest and strongest
jaws and the widest zygomatic aperture, have the muscles so large that
they meet on the crown of the skull, and deposit the bony ridge which
supports them, and which is the highest in that which has the
smallest cranial surface. In those which combine a large surface with
comparatively weak jaws, and small zygomatic aperture, the muscles, on
each side, do not extend to the crown, a space of from l to 2 inches
remaining between them, and along their margins small ridges are formed.
Intermediate forms are found, in which the ridges meet only in the
hinder part of the skull. The form and size of the ridges are therefore
independent of age, being sometimes more strongly developed in the less
aged animal. Professor Temminck states that the series of skulls in the
Leyden Museum shows the same result."
Mr. Wallace observed two male adult Orangs (Mias Kassu of the Dyaks),
however, so very different from any of these that he concludes them to
be specifically distinct; they were respectively 3 feet 8 1/2 inches
and 3 feet 9 1/2 inches high, and possessed no sign of the cheek
excrescences, but otherwise resembled the larger kinds. The skull has
no crest, but two bony ridges, 1 3/4 inches to 2 inches apart, as in
the 'Simia morio' of Professor Owen. The teeth, however; are immense,
equalling or surpassing those of the other species. The females of both
these kinds, according to Mr. Wallace, are devoid of excrescences, and
resemble the smaller males, but are shorter by 1 1/2 to 3 inches, and
their canine teeth are comparatively small, subtruncated and dilated
at the base, as in the so-called 'Simia morio', which is, in all
probability, the skull of a female of the same species as the
smaller males. Both males and females of this smaller species are
distinguishable, according to Mr. Wallace, by the comparatively large
size of the middle incisors of the upper jaw.
So far as I am aware, no one has attempted to dispute the accuracy of
the statements which I have just quoted regarding the habits of the two
Asiatic man-like Apes; and if true, they must be admitted as evidence,
that such an Ape--
Firstly, May readily move along the ground in the erect, or semi-erect,
position, and without direct support from its arms.
Secondly, That it may possess an extremely loud voice, so loud as to be
readily heard one or two miles.
Thirdly, That it may be capable of great viciousness and violence when
irritated: and this is especially true of adult males.
Fourthly, That it may build a nest to sleep in.
Such being well established facts respecting the Asiatic Anthropoids,
analogy alone might justify us in expecting the African species to offer
similar peculiarities, separately or combined; or, at any rate, would
destroy the force of any attempted a priori argument against such direct
testimony as might be adduced in favour of their existence. And, if the
organization of any of the African Apes could be demonstrated to fit it
better than either of its Asiatic allies for the erect position and
for efficient attack, there would be still less reason for doubting
its occasional adoption of the upright attitude or of aggressive
proceedings.
From the time of Tyson and Tulpius downwards, the habits of the young
CHIMPANZEE in a state of captivity have been abundantly reported and
commented upon. But trustworthy evidence as to the manners and customs
of adult anthropoids of this species, in their native woods, was almost
wanting up to the time of the publication of the paper by Dr. Savage,
to which I have already referred; containing notes of the observations
which he made, and of the information which he collected from sources
which he considered trustworthy, while resident at Cape Palmas, at the
north-western limit of the Bight of Benin.
The adult Chimpanzees, measured by Dr. Savage, never exceeded, though
the males may almost attain, five feet in height.
"When at rest, the sitting posture is that generally assumed. They
are sometimes seen standing and walking, but when thus detected,
they immediately take to all fours, and flee from the presence of the
observer. Such is their organization that they cannot stand erect, but
lean forward. Hence they are seen, when standing, with the hands clasped
over the occiput, or the lumbar region, which would seem necessary to
balance or ease of posture.
"The toes of the adult are strongly flexed and turned inwards, and
cannot be perfectly straightened. In the attempt the skin gathers into
thick folds on the back, shewing that the full expansion of the foot,
as is necessary in walking, is unnatural. The natural position is on all
fours, the body anteriorly resting upon the knuckles. These are greatly
enlarged, with the skin protuberant and thickened like the sole of the
foot.
"They are expert climbers, as one would suppose from their organization.
In their gambols they swing from limb to limb to a great distance, and
leap with astonishing agility. It is not unusual to see the 'old
folks' (in the language of an observer) sitting under a tree regaling
themselves with fruit and friendly chat, while their 'children' are
leaping around them, and swinging from tree to tree with boisterous
merriment.
"As seen here, they cannot be called 'gregarious', seldom more than
five, or ten at most, being found together. It has been said, on good
authority, that they occasionally assemble in large numbers, in gambols.
My informant asserts that he saw once not less than fifty so engaged;
hooting, screaming, and drumming with sticks upon old logs, which is
done in the latter case with equal facility by the four extremities.
They do not appear ever to act on the offensive, and seldom, if ever
really, on the defensive. When about to be captured, they resist by
throwing their arms about their opponent, and attempting to draw him
into contact with their teeth." (Savage, l. c. p. 384.)
With respect to this last point Dr. Savage is very explicit in another
place:
"BITING is their principal art of defence. I have seen one man who had
been thus severely wounded in the feet.
"The strong development of the canine teeth in the adult would seem
to indicate a carnivorous propensity; but in no state save that of
domestication do they manifest it. At first they reject flesh, but
easily acquire a fondness for it. The canines are early developed, and
evidently designed to act the important part of weapons of defence. When
in contact with man almost the first effort of the animal is--TO BITE.
"They avoid the abodes of men, and build their habitations in trees.
Their construction is more that of NESTS than HUTS, as they have been
erroneously termed by some naturalists. They generally build not far
above the ground. Branches or twigs are bent, or partly broken, and
crossed, and the whole supported by the body of a limb or a crotch.
Sometimes a nest will be found near the END of a STRONG LEAFY BRANCH
twenty or thirty feet from the ground. One I have lately seen that could
not be less than forty feet, and more probably it was fifty. But this is
an unusual height.
"Their dwelling-place is not permanent, but changed in pursuit of food
and solitude, according to the force of circumstances. We more often
see them in elevated places; but this arises from the fact that the
low grounds, being more favourable for the natives' rice-farms, are the
oftener cleared, and hence are almost always wanting in suitable trees
for their nests...It is seldom that more than one or two nests are seen
upon the same tree, or in the same neighbourhood: five have been found,
but it was an unusual circumstance."...
"They are very filthy in their habits...It is a tradition with the
natives generally here, that they were once members of their own
tribe; that for their depraved habits they were expelled from all
human society, and, that through an obstinate indulgence of their
vile propensities, they have degenerated into their present state and
organization. They are, however, eaten by them, and when cooked with the
oil and pulp of the palm-nut considered a highly palatable morsel.
"They exhibit a remarkable degree of intelligence in their habits, and,
on the part of the mother, much affection for their young. The second
female described was upon a tree when first discovered, with her mate
and two young ones (a male and a female). Her first impulse was to
descend with great rapidity, and make off into the thicket, with her
mate and female offspring. The young male remaining behind, she soon
returned to the rescue. She ascended and took him in her arms, at which
moment she was shot, the ball passing through the forearm of the young
one, on its way to the heart of the mother....
"In a recent case, the mother, when discovered, remained upon the tree
with her offspring, watching intently the movements of the hunter. As he
took aim, she motioned with her hand, precisely in the manner of a human
being, to have him desist and go away. When the wound has not proved
instantly fatal, they have been known to stop the flow of blood by
pressing with the hand upon the part, and when this did not succeed,
to apply leaves and grass...When shot, they give a sudden screech, not
unlike that of a human being in sudden and acute distress."
The ordinary voice of the Chimpanzee, however, is affirmed to be hoarse,
guttural, and not very loud, somewhat like "whoo-whoo." (l. c. p. 365).
The analogy of the Chimpanzee to the Orang, in its nest-building habit
and in the mode of forming its nest, is exceedingly interesting; while,
on the other hand, the activity of this ape, and its tendency to bite,
are particulars in which it rather resembles the Gibbons. In extent of
geographical range, again, the Chimpanzees--which are found from Sierra
Leone to Congo--remind one of the Gibbons, rather than of either of the
other man-like apes; and it seems not unlikely that, as is the case with
the Gibbons, there may be several species spread over the geographical
area of the genus.
The same excellent observer, from whom I have borrowed the preceding
account of the habits of the adult Chimpanzee, published fifteen years
ago,* an account of the GORILLA, which has, in its most essential
points, been confirmed by subsequent observers, and to which so very
little has really been added, that in justice to Dr. Savage I give
it almost in full. ([Footnote] *Notice of the external characters and
habits of Troglodytes Gorilla. 'Boston Journal of Natural History',
1847.)
"It should be borne in mind that my account is based upon the statements
of the aborigines of that region (the Gaboon). In this connection,
it may also be proper for me to remark, that having been a missionary
resident for several years, studying, from habitual intercourse, the
African mind and character, I felt myself prepared to discriminate and
decide upon the probability of their statements. Besides, being familiar
with the history and habits of its interesting congener ('Trog. niger',
Geoff.), I was able to separate their accounts of the two animals,
which, having the same locality and a similarity of habit, are
confounded in the minds of the mass, especially as but few--such as
traders to the interior and huntsmen--have ever seen the animal in
question.
(FIGURE 10.--The Gorilla (after Wolff).)
"The tribe from which our knowledge of the animal is derived, and whose
territory forms its habitat, is the 'Mpongwe', occupying both banks of
the River Gaboon, from its mouth to some fifty or sixty miles upward....
"If the word 'Pongo' be of African origin, it is probably a corruption
of the word 'Mpongwe', the name of the tribe on the banks of the Gaboon,
and hence applied to the region they inhabit. Their local name for the
Chimpanzee is 'Enche-eko', as near as it can be Anglicized, from which
the common term 'Jocko' probably comes. The Mpongwe appellation for its
new congener is 'Enge-ena', prolonging the sound of the first vowel, and
slightly sounding the second.
"The habitat of the 'Enge-ena' is the interior of lower Guinea, whilst
that of the 'Enche-eko' is nearer the sea-board.
"Its height is about five feet; it is disproportionately broad across
the shoulders, thickly covered with coarse black hair, which is said to
be similar in its arrangement to that of the 'Enche-eko'; with age it
becomes grey, which fact has given rise to the report that both animals
are seen of different colours.
"HEAD.--The prominent features of the head are, the great width and
elongation of the face, the depth of the molar region, the branches
of the lower jaw being very deep and extending far backward, and the
comparative smallness of the cranial portion; the eyes are very large,
and said to be like those of the Enche-eko, a bright hazel; nose broad
and flat, slightly elevated towards the root; the muzzle broad, and
prominent lips and chin, with scattered gray hairs; the under lip highly
mobile, and capable of great elongation when the animal is enraged, then
hanging over the chin; skin of the face and ears naked, and of a dark
brown, approaching to black.
"The most remarkable feature of the head is a high ridge, or crest of
hair, in the course of the sagittal suture, which meets posteriorily
with a transverse ridge of the same, but less prominent, running round
from the back of one ear to the other. The animal has the power of
moving the scalp freely forward and back, and when enraged is said to
contract it strongly over the brow, thus bringing down the hairy
ridge and pointing the hair forward, so as to present an indescribably
ferocious aspect.
"Neck short, thick, and hairy; chest and shoulders very broad, said to
be fully double the size of the Enche-ekos; arms very long, reaching
some way below the knee--the fore-arm much the shortest; hands very
large, the thumbs much larger than the fingers...
(FIGURE 11.--Gorilla walking (after Wolff).)
"The gait is shuffling; the motion of the body, which is never upright
as in man, but bent forward, is somewhat rolling, or from side to side.
The arms being longer than the Chimpanzee, it does not stoop as much in
walking; like that animal, it makes progression by thrusting its arms
forward, resting the hands on the ground, and then giving the body a
half jumping half swinging motion between them. In this act it is
said not to flex the fingers, as does the Chimpanzee, resting on its
knuckles, but to extend them, making a fulcrum of the hand. When it
assumes the walking posture, to which it is said to be much inclined, it
balances its huge body by flexing its arms upward.
"They live in bands, but are not so numerous as the Chimpanzees: the
females generally exceed the other sex in number. My informants all
agree in the assertion that but one adult male is seen in a band; that
when the young males grow up, a contest takes place for mastery, and the
strongest, by killing and driving out the others, establishes himself as
the head of the community."
Dr. Savage repudiates the stories about the Gorillas carrying off women
and vanquishing elephants and then adds:
"Their dwellings, if they may be so called, are similar to those of
the Chimpanzee, consisting simply of a few sticks and leafy branches,
supported by the crotches and limbs of trees: they afford no shelter,
and are occupied only at night.
"They are exceedingly ferocious, and always offensive in their habits,
never running from man, as does the Chimpanzee. They are objects of
terror to the natives, and are never encountered by them except on
the defensive. The few that have been captured were killed by elephant
hunters and native traders, as they came suddenly upon them while
passing through the forests.
"It is said that when the male is first seen he gives a terrific yell,
that resounds far and wide through the forest, something like kh-ah!
kh-ah! prolonged and shrill. His enormous jaws are widely opened at each
expiration, his under lip hangs over the chin, and the hairy ridge
and scalp are contracted upon the brow, presenting an aspect of
indescribable ferocity.
"The females and young, at the first cry, quickly disappear. He then
approaches the enemy in great fury, pouring out his horrid cries in
quick succession. The hunter awaits his approach with his gun extended:
if his aim is not sure, he permits the animal to grasp the barrel, and
as he carries it to his mouth (which is his habit) he fires. Should the
gun fail to go off, the barrel (that of the ordinary musket, which is
thin) is crushed between his teeth, and the encounter soon proves fatal
to the hunter.
"In the wild state, their habits are in general like those of the
'Troglodytes niger', building their nests loosely in trees, living
on similar fruits, and changing their place of resort from force of
circumstances."
Dr. Savage's observations were confirmed and supplemented by those of
Mr. Ford, who communicated an interesting paper on the Gorilla to
the Philadelphian Academy of Sciences, in 1852. With respect to the
geographical distribution of this greatest of all the man-like Apes, Mr.
Ford remarks:
"This animal inhabits the range of mountains that traverse the interior
of Guinea, from the Cameroon in the north, to Angola in the south, and
about 100 miles inland, and called by the geographers Crystal Mountains.
The limit to which this animal extends, either north or south, I am
unable to define. But that limit is doubtless some distance north of
this river (Gaboon). I was able to certify myself of this fact in a late
excursion to the head-waters of the Mooney (Danger) River, which comes
into the sea some sixty miles from this place. I was informed (credibly,
I think) that they were numerous among the mountains in which that river
rises, and far north of that.
"In the south, this species extends to the Congo River, as I am told by
native traders who have visited the coast between the Gaboon and that
river. Beyond that, I am not informed. This animal is only found at
a distance from the coast in most cases, and, according to my best
information, approaches it nowhere so nearly as on the south side of
this river, where they have been found within ten miles of the sea.
This, however, is only of late occurrence. I am informed by some of the
oldest Mpongwe men that formerly he was only found on the sources of the
river, but that at present he may be found within half-a-day's walk of
its mouth. Formerly he inhabited the mountainous ridge where Bushmen
alone inhabited, but now he boldly approaches the Mpongwe plantations.
This is doubtless the reason of the scarcity of information in years
past, as the opportunities for receiving a knowledge of the animal have
not been wanting; traders having for one hundred years frequented this
river, and specimens, such as have been brought here within a year,
could not have been exhibited without having attracted the attention of
the most stupid."
One specimen Mr. Ford examined weighed 170 1bs., without the thoracic,
or pelvic, viscera, and measured four feet four inches round the chest.
This writer describes so minutely and graphically the onslaught of the
Gorilla--though he does not for a moment pretend to have witnessed the
scene--that I am tempted to give this part of his paper in full, for
comparison with other narratives:
"He always rises to his feet when making an attack, though he approaches
his antagonist in a stooping posture.
"Though he never lies in wait, yet, when he hears, sees, or scents
a man, he immediately utters his characteristic cry, prepares for an
attack, and always acts on the offensive. The cry he utters resembles
a grunt more than a growl, and is similar to the cry of the Chimpanzee,
when irritated, but vastly louder. It is said to be audible at a great
distance. His preparation consists in attending the females and young
ones, by whom he is usually accompanied, to a little distance. He,
however, soon returns, with his crest erect and projecting forward,
his nostrils dilated, and his under-lip thrown down; at the same time
uttering his characteristic yell, designed, it would seem, to terrify
his antagonist. Instantly, unless he is disabled by a well directed
shot, he makes an onset, and, striking his antagonist with the palm of
his hands, or seizing him with a grasp from which there is no escape, he
dashes him upon the ground, and lacerates him with his tusks.
"He is said to seize a musket, and instantly crush the barrel between
his teeth...This animal's savage nature is very well shown by the
implacable desperation of a young one that was brought here. It was
taken very young, and kept four months, and many means were used to tame
it; but it was incorrigible, so that it bit me an hour before it died."
Mr. Ford discredits the house-building and elephant-driving stories, and
says that no well-informed natives believe them. They are tales told to
children.
I might quote other testimony to a similar effect, but, as it appears to
me, less carefully weighed and sifted, from the letters of MM. Franquet
and Gautier Laboullay, appended to the memoir of M. I. G. St. Hilaire,
which I have already cited.
Bearing in mind what is known regarding the Orang and the Gibbon, the
statements of Dr. Savage and Mr. Ford do not appear to me to be justly
open to criticism on 'a priori' grounds. The Gibbons, as we have seen,
readily assume the erect posture, but the Gorilla is far better fitted
by its organization for that attitude than are the Gibbons: if the
laryngeal pouches of the Gibbons, as is very likely, are important
in giving volume to a voice which can be heard for half a league, the
Gorilla, which has similar sacs, more largely developed, and whose
bulk is fivefold that of a Gibbon, may well be audible for twice
that distance. If the Orang fights with its hands, the Gibbons and
Chimpanzees with their teeth, the Gorilla may, probably enough,
do either or both; nor is there anything to be said against either
Chimpanzee or Gorilla building a nest, when it is proved that the
Orang-Utan habitually performs that feat.
With all this evidence, now ten to fifteen years old, before the world
it is not a little surprising that the assertions of a recent traveller,
who, so far as the Gorilla is concerned, really does very little more
than repeat, on his own authority, the statements of Savage and of Ford,
should have met with so much and such bitter opposition. If subtraction
be made of what was known before, the sum and substance of what M. Du
Chaillu has affirmed as a matter of his own observation respecting the
Gorilla, is, that, in advancing to the attack, the great brute beats his
chest with his fists. I confess I see nothing very improbable, or very
much worth disputing about, in this statement.
With respect to the other man-like Apes of Africa, M. Du Chaillu tells
us absolutely nothing, of his own knowledge, regarding the common
Chimpanzee; but he informs us of a bald-headed species or variety, the
'nschiego mbouve', which builds itself a shelter, and of another rare
kind with a comparatively small face, large facial angle, and peculiar
note, resembling "Kooloo."
As the Orang shelters itself with a rough coverlet of leaves, and the
common Chimpanzee, according to that eminently trustworthy observer
Dr. Savage, makes a sound like "Whoo-whoo,"--the grounds of the summary
repudiation with which M. Du Chaillu's statements on these matters have
been met are not obvious.
If I have abstained from quoting M. Du Chaillu's work, then, it is
not because I discern any inherent improbability in his assertions
respecting the man-like Apes; nor from any wish to throw suspicion
on his veracity; but because, in my opinion, so long as his narrative
remains in its present state of unexplained and apparently inexplicable
confusion, it has no claim to original authority respecting any subject
whatsoever.
It may be truth, but it is not evidence.
End of Man-like apes.
