PREFACE TO THE THIRD EDITION.
The present edition, which appears on the same general plan as before,
will yet be found to have been in great part re-written, enlarged, and
corrected.
Analytical methods which experience has shown to be faulty have been
omitted, and replaced by newer and more accurate processes.
The intimate connection which recent research has shown to exist between
the arrangement of the constituent parts of an organic molecule and
physiological action, has been considered at some length in a separate
chapter.
The cadaveric alkaloids or ptomaines, bodies playing so great a part in
food-poisoning and in the manifestations of disease, are in this edition
treated of as fully as the limits of the book will allow.
The author, therefore, trusts that these various improvements,
modifications, and corrections will enable “POISONS” to maintain the
position which it has for so many years held in the esteem of
toxicologists and of the medical profession generally.

POISONS:
THEIR EFFECTS AND DETECTION.
PART I.--INTRODUCTORY.
I.--The Old Poison-Lore.
§ 1. It is significant that the root “_tox_” of the modern word
_toxicology_ can be traced back to a very ancient word meaning “bow” or
“arrow,” or, in its broadest sense, some “tool” used for slaying: hence
it is no far-fetched supposition that the first poison-knowledge was
that of the septic poisons. Perchance the savage found that weapons
soiled with the blood of former victims made wounds fatal; from this
observation the next step naturally would be that of experiment--the
arrow or spear would be steeped in all manner of offensive pastes, and
smeared with the vegetable juices of those plants which were deemed
noxious; and as the effects were mysterious, they would be ascribed to
the supernatural powers, and covered with a veil of superstition.
The history of the _poison-lehre_, like all history, begins in the
region of the myths: there was a dark saga prevailing in Greece, that in
the far north existed a land ruled by sorcerers--all children of the
sun--and named Aeëtes, Perses, Hecate, Medea, and Circe. Later on, the
enchanted land was localised at Colchis, and Aeëtes and Perses were said
to be brothers. Hecate was the daughter of Perses; she was married to
Aeëtes, and their daughters were Medea and Circe. Hecate was the
discoverer of poisonous herbs, and learned in remedies both evil and
good. Her knowledge passed to Medea, who narcotised the dragon, the
guardian of the golden fleece, and incited Jason to great undertakings.
In the expedition of the Argonauts, the poets loved to describe Hecate’s
garden, with its lofty walls. Thrice-folding doors of ebony barred the
entrance, which was guarded by terrible forms: only the initiated few,
only they who bore the leavened rod of expiation, and the concealed
conciliatory offering of the Medea, could enter into the sanctuary.
Towering above all was the temple of the dread Hecate, whose priestesses
offered to the gods ghastly sacrifices.
§ 2. The oldest Egyptian king, Menes, and Attalus Phylometer, the last
king of Pergamus, were both famous for their knowledge of plants.
Attalus Phylometer was acquainted with hyoscyamus, aconite, conium,
veratrum, and others; he experimented on the preparation of poisons, and
occupied himself in compounding medicines. Mithradetes Eupator stood yet
higher: the receipt for the famous _theriaca_, prepared in later years
at an enormous price, and composed of fifty-four different ingredients,
is ascribed to him. The wonderful skill shown by the Egyptians in
embalming and technical works is sufficient to render it fairly certain
that their chemical knowledge was considerable; and the frequent
operations of one caste upon the dead must have laid the foundations of
a pathological and anatomical culture, of which only traces remain.
The Egyptians knew prussic acid as extracted in a dilute state from
certain plants, among the chief of which was certainly the peach; on a
papyrus preserved at the Louvre, M. Duteil read, “Pronounce not the name
of I. A. O. under the penalty of the peach!” in which dark threat,
without doubt, lurks the meaning that those who revealed the religious
mysteries of the priests were put to death by waters distilled from the
peach. That the priests actually distilled the peach-leaves has been
doubted by those who consider the art of distillation a modern
invention; but this process was well known to adepts of the third and
fourth centuries, and there is no inherent improbability in the
supposition that the Egyptians practised it.
§ 3. From the Egyptians the knowledge of the deadly drink appears to
have passed to the Romans. At the trial of Antipater,[1] Verus brought a
potion derived from Egypt, which had been intended to destroy Herod;
this was essayed on a criminal, he died at once. In the reign of
Tiberius, a Roman knight, accused of high treason, swallowed a poison,
and fell dead at the feet of the senators: in both cases the rapidity of
action appears to point to prussic acid.
[1] Jos. Ant., B. xvii. c. 5.
The use of poison by the Greeks, as a means of capital punishment,
without doubt favoured suicide by the same means; the easy, painless
death of the state prisoner would be often preferred to the sword by one
tired of life. The ancients looked indeed upon suicide, in certain
instances, as something noble, and it was occasionally formally
sanctioned. Thus, Valerius Maximus tells us that he saw a woman of
quality, in the island of Ceos, who, having lived happily for ninety
years, obtained leave to take a poisonous draught, lest, by living
longer, she should happen to have a change in her good fortune; and,
curiously enough, this sanctioning of self-destruction seems to have
been copied in Europe. Mead relates that the people of Marseilles of old
had a poison, kept by the public authorities, in which cicuta was an
ingredient: a dose was allowed to any one who could show why he should
desire death. Whatever use or abuse might be made of a few violent
poisons, Greek and Roman knowledge of poisons, their effects and methods
of detection, was stationary, primitive, and incomplete.
_Nicander of Colophon_ (204-138 B.C.) wrote two treatises, the most
ancient works on this subject extant, the one describing the effects of
snake venom; the other, the properties of opium, henbane, certain fungi,
colchicum, aconite, and conium. He divided poisons into those which kill
quickly, and those which act slowly. As antidotes, those medicines are
recommended which excite vomiting--_e.g._, lukewarm oil, warm water,
mallow, linseed tea, &c.
_Apollodorus_ lived at the commencement of the third century B.C.: he
wrote a work on poisonous animals, and one on deleterious medicines;
these works of Apollodorus were the sources from which Pliny,
Heraclitus, and several of the later writers derived most of their
knowledge of poisons.
_Dioscorides_ (40-90 A.D.) well detailed the effects of cantharides,
sulphate of copper, mercury, lead, and arsenic. By arsenic he would
appear sometimes to mean the sulphides, sometimes the white oxide.
Dioscorides divided poisons, according to their origin, into three
classes, viz.:--
1. =Animal Poisons.=--Under this head were classed cantharides and
allied beetles, toads, salamanders, poisonous snakes, a particular
variety of honey, and the blood of the ox, probably the latter in a
putrid state. He also speaks of the “_sea-hare_.” The sea-hare was
considered by the ancients very poisonous, and Domitian is said to have
murdered Titus with it. It is supposed by naturalists to have been one
of the genus _Aplysia_, among the _gasteropods_. Both Pliny and
Dioscorides depict the animal as something very formidable: it was not
to be looked at, far less touched. The aplysiæ exhale a very nauseous
and fœtid odour when they are approached: the best known of the species
resembles, when in a state of repose, a mass of unformed flesh; when in
motion, it is like a common slug; its colour is reddish-brown; it has
four horns on its head; and the eyes, which are very small, are situated
between the two hinder ones. This aplysia has an ink reservoir, like the
sepia, and ejects it in order to escape from its enemies; it inhabits
the muddy bottom of the water, and lives on small crabs, mollusca, &c.
2. =Poisons from Plants.=--Dioscorides enumerates opium, black and white
hyoscyamus (especially recognising the activity of the seeds),
mandragora, which was probably a mixture of various solanaceæ, conium
(used to poison the condemned by the people of Athens and the dwellers
of ancient Massilia), elaterin, and the juices of a species of euphorbia
and apocyneæ. He also makes a special mention of aconite, the name of
which is derived from _Akon_, a small city in Heraclea. The Greeks were
well aware of the deadly nature of aconite, and gave to it a mythical
origin, from the foam of the dog Cerberus. Colchicum was also known to
Dioscorides: its first use was ascribed to Medea. Veratrum album and
nigrum were famous medicines of the Romans, and a constituent of their
“_rat and mice powders_;” they were also used as insecticides. According
to Pliny, the Gauls dipped their arrows in a preparation of veratrum.[2]
Daphne mezereon, called by the Romans also smilax and taxus, appears to
have been used by Cativolcus, the king of the Eburones, for the purpose
of suicide, or possibly by “taxus” the yew-tree is meant.[3]
[2] Pliny, xxv. 5.
[3] _De Bello Gallico_, vi. 31.
The poisonous properties of certain fungi were also known. Nicander
calls the venomous mushrooms the “evil fermentation of the earth,” and
prescribes the identical antidotes which we would perhaps give at the
present time--viz., vinegar and alkaline carbonates.
3. =Mineral Poisons.=--Arsenic has been already alluded to. The ancients
used it as a caustic and depilatory. Copper was known as sulphate and
oxide; mercury only as cinnabar: lead oxides were used, and milk and
olive-oil prescribed as an antidote for their poisonous properties. The
_poison-lehre_ for many ages was considered as something forbidden.
Galen, in his treatise “On Antidotes,” remarks that the only authors who
dared to treat of poisons were Orpheus, Theologus, Morus, Mendesius the
younger, Heliodorus of Athens, Aratus, and a few others; but none of
these treatises have come down to us. From the close similarity of the
amount of information in the treatises of Nicander, Dioscorides, Pliny,
Galen, and Paulus Ægineta, it is probable that all were derived from a
common source.
§ 4. If we turn our attention to early Asiatic history, a very cursory
glance at the sacred writings of the East will prove how soon the art of
poisoning, especially in India, was used for the purpose of suicide,
revenge, or robbery.
The ancient practice of the Hindoo widow--self-immolation on the burning
pile of her husband--is ascribed to the necessity which the Brahmins
were under of putting a stop to the crime of domestic poisoning. Every
little conjugal quarrel was liable to be settled by this form of secret
assassination, but such a law, as might be expected, checked the
practice.
Poison was not used to remove human beings alone, for there has been
from time immemorial in India much cattle-poisoning. In the Institutes
of Menu, it is ordained that when cattle die the herdsman shall carry to
his master their ears, their hides, their tails, the skin below their
navels, their tendons, and the liquor oozing from their foreheads.
Without doubt these regulations were directed against cattle-poisoners.
The poisons known to the Asiatics were arsenic, aconite, opium, and
various solanaceous plants. There has been a myth floating through the
ages that a poison exists which will slay a long time after its
introduction. All modern authors have treated the matter as an
exaggerated legend, but, for my own part, I see no reason why it should
not, in reality, be founded on fact. There is little doubt that the
Asiatic poisoners were well acquainted with the infectious qualities of
certain fevers and malignant diseases. Now, these very malignant
diseases answer precisely to the description of a poison which has no
immediate effects. Plant small-pox in the body of a man, and for a whole
fortnight he walks about, well and hearty. Clothe a person with a
garment soaked in typhus, and the same thing occurs--for many days there
will be no sign of failure. Again, the gipsies, speaking a tongue which
is essentially a deformed _prakrit_, and therefore Indian in origin,
have long possessed a knowledge of the properties of the curious “_mucor
phycomyces_.” This was considered an alga by Agaron, but Berkeley
referred it to the fungi. The gipsies are said to have administered the
spores of this fungi in warm water. In this way they rapidly attach
themselves to the mucous membrane of the throat, all the symptoms of a
phthisis follow, and death takes place in from two to three weeks. Mr
Berkeley informed me that he has seen specimens growing on broth which
had been rejected from the stomach, and that it develops in enormous
quantities on oil-casks and walls impregnated with grease. The filaments
are long, from 12 to 18 inches, and it is capable of very rapid
development.
There is also a modern poison, which, in certain doses, dooms the
unfortunate individual to a terrible malady, simulating, to a
considerable extent, natural disease,--that is phosphorus. This poison
was, however, unknown until some time in the eleventh century, when
Alchid Becher, blindly experimenting on the distillation of urine and
carbon, obtained his “_escarboucle_,” and passed away without knowing
the importance of his discovery, which, like so many others, had to be
rediscovered at a later period.
§ 5. The Hebrews were acquainted with certain poisons, the exact nature
of which is not quite clear. The words “_rosch_” and “_chema_” seem to
be used occasionally as a generic term for poison, and sometimes to mean
a specific thing; “_rosch_,” especially, is used to signify some
poisonous parasitic plant. They knew yellow arsenic under the name of
“_sam_,” aconite under the name of “_boschka_,” and possibly “_son_”
means _ergot_.[4] In the later period of their history, when they were
dispersed through various nations, they would naturally acquire the
knowledge of those nations, without losing their own.

§ 6. The part that poison has played in history is considerable. The
pharmaceutical knowledge of the ancients is more graphically and
terribly shown in the deaths of Socrates, Demosthenes, Hannibal, and
Cleopatra, than in the pages of the older writers on poisons.
In the reign of Artaxerxes II. (Memnon), (B.C. 405-359), Phrysa poisoned
the queen Statira by cutting food with a knife poisoned on one side
only. Although this has been treated as an idle tale, yet two poisons,
aconite and arsenic, were at least well known; either of these could
have been in the way mentioned introduced in sufficient quantity into
food to destroy life.
In the early part of the Christian era professional poisoners arose, and
for a long time exercised their trade with impunity. Poisoning was so
much in use as a political engine that Agrippina (A.D. 26) refused to
eat of some apples offered to her at table by her father-in-law,
Tiberius.
It was at this time that the infamous Locusta flourished. She is said to
have supplied, with suitable directions, the poison by which Agrippina
got rid of Claudius; and the same woman was the principal agent in the
preparation of the poison that was administered to Britannicus, by order
of his brother Nero. The details of this interesting case have been
recorded with some minuteness.
It was the custom of the Romans to drink hot water, a draught nauseous
enough to us, but, from fashion or habit, considered by them a luxury;
and, as no two men’s tastes are alike, great skill was shown by the
slaves in bringing the water to exactly that degree of heat which their
respective masters found agreeable.[5]
[5] Tacitus, lib. xii., xiii. Mentioned also by Juvenal and Suetonius.
The children of the Imperial house, with others of the great Roman
families, sat at the banquets at a smaller side table, while their
parents reclined at the larger. A slave brings hot water to Britannicus;
it is too hot; Britannicus refuses it. The slave adds cold water; and it
is this cold water that is supposed to have been poisoned; in any case,
Britannicus had no sooner drunk of it than he lost voice and
respiration. Agrippina, his mother, was struck with terror, as well as
Octavia, his sister. Nero, the author of the crime, looks coldly on,
saying that such fits often happened to him in infancy without evil
result; and after a few moments’ silence the banquet goes on as before.
If this were not sudden death from heart or brain disease, the poison
must have been either a cyanide or prussic acid.
In those times no autopsy was possible: although the Alexandrian school,
some 300 years before Christ, had dissected both the living and the
dead, the work of Herophilus and Erasistratus had not been pursued, and
the great Roman and Greek writers knew only the rudiments of human
anatomy, while, as to pathological changes and their true
interpretation, their knowledge may be said to have been absolutely
_nil_. It was not, indeed, until the fifteenth century that the Popes,
silencing ancient scruples, authorised dissections; and it was not until
the sixteenth century that Vesalius, the first worthy of being
considered a great anatomist, arose. In default of pathological
knowledge, the ancients attached great importance to mere outward marks
and discolorations. They noted with special attention spots and
lividity, and supposed that poisons singled out the heart for some quite
peculiar action, altering its substance in such a manner that it
resisted the action of the funeral pyre, and remained unconsumed. It
may, then, fairly be presumed that many people must have died from
poison without suspicion, and still more from the sudden effects of
latent disease, ascribed wrongfully to poison. For example, the death of
Alexander was generally at that time ascribed to poison; but Littré has
fairly proved that the great emperor, debilitated by his drinking
habits, caught a malarious fever in the marshes around Babylon, and died
after eleven days’ illness. If, added to sudden death, the body, from
any cause, entered into rapid putrefaction, such signs were considered
by the people absolutely conclusive of poisoning: this belief, indeed,
prevailed up to the middle of the seventeenth century, and lingers still
among the uneducated at the present day. Thus, when Britannicus died, an
extraordinary lividity spread over the face of the corpse, which they
attempted to conceal by painting the face. When Pope Alexander VI. died,
probably enough from poison, his body (according to Guicciardini) became
a frightful spectacle--it was livid, bloated, and deformed; the gorged
tongue entirely filled the mouth; from the nose flowed putrid pus, and
the stench was horrible in the extreme.
All these effects of decomposition, we know, are apt to arise in coarse,
obese bodies, and accompany both natural and unnatural deaths; indeed,
if we look strictly at the matter, putting on one side the preservative
effects of certain metallic poisons, it may be laid down that generally
the corpses of those dying from poison are _less_ apt to decompose
rapidly than those dying from disease--this for the simple reason that a
majority of diseases cause changes in the fluids and tissues, which
render putrefactive changes more active, while, as a rule, those who
take poison are suddenly killed, with their fluids and tissues fairly
healthy.
When the Duke of Burgundy desired to raise a report that John, Dauphin
of France, was poisoned (1457), he described the imaginary event as
follows:--
“One evening our most redoubtable lord and nephew fell so grievously
sick that he died forthwith. His lips, tongue, and face were swollen;
his eyes started out of his head. It was a horrible sight to see--for so
look people that are poisoned.”
The favourite powder of the professional poisoner, arsenic, was known to
crowned heads in the fourteenth century; and there has come down to us a
curious document, drawn out by Charles le Mauvais, King of Navarre. It
is a commission of murder, given to a certain Woudreton, to poison
Charles VI., the Duke of Valois, brother of the king, and his uncles,
the Dukes of Berry, Burgundy, and Bourbon:--
“Go thou to Paris; thou canst do great service if thou wilt: do what I
tell thee; I will reward thee well. Thou shalt do thus: There is a thing
which is called sublimed arsenic; if a man eat a bit the size of a pea
he will never survive. Thou wilt find it in Pampeluna, Bordeaux,
Bayonne, and in all the good towns through which thou wilt pass, at the
apothecaries’ shops. Take it and powder it; and when thou shalt be in
the house of the king, of the Count de Valois, his brother, the Dukes of
Berry, Burgundy, and Bourbon, draw near, and betake thyself to the
kitchen, to the larder, to the cellar, or any other place where thy
point can be best gained, and put the powder in the soups, meats, or
wines, provided that thou canst do it secretly. Otherwise, do it not.”
Woudreton was detected, and executed in 1384.[6]

A chapter might be written entitled “royal poisoners.” King Charles IX.
even figures as an experimentalist.[7] An unfortunate cook has stolen
two silver spoons, and, since there was a question whether “_Bezoar_”
was an antidote or not, the king administers to the cook a lethal dose
of corrosive sublimate, and follows it up with the antidote; but the man
dies in seven hours, although Paré also gives him oil. Truly a grim
business!

The subtle method of removing troublesome subjects has been more often
practised on the Continent than in England, yet the English throne in
olden time is not quite free from this stain.[8] The use of poison is
wholly opposed to the Anglo-Saxon method of thought. To what anger the
people were wrought on detecting poisoners, is seen in the fact that, in
1542, a young woman was boiled alive in Smithfield for poisoning three
households.[9]
[8] For example, King John is believed to have poisoned Maud Fitzwalter
by “a poisoned egg.”
“In the reign of King John, the White Tower received one of the first
and fairest of a long line of female victims in that Maud Fitzwalter who
was known to the singers of her time as Maud the Fair. The father of
this beautiful girl was Robert, Lord Fitzwalter, of Castle Baynard, on
the Thames, one of John’s greatest barons. Yet the king, during a fit of
violence with the queen, fell madly in love with this young girl. As
neither the lady herself nor her powerful sire would listen to his
disgraceful suit, the king is said to have seized her by force at
Dunmow, and brought her to the Tower. Fitzwalter raised an outcry, on
which the king sent troops into Castle Baynard and his other houses; and
when the baron protested against these wrongs, his master banished him
from the realm. Fitzwalter fled to France with his wife and his other
children, leaving his daughter Maud in the Tower, where she suffered a
daily insult in the king’s unlawful suit. On her proud and scornful
answer to his passion being heard, John carried her up to the roof, and
locked her in the round turret, standing on the north-east angle of the
keep. Maud’s cage was the highest, chilliest den in the Tower; but
neither cold, nor solitude, nor hunger could break her strength. In the
rage of his disappointed love, the king sent one of his minions to her
room with a poisoned egg, of which the brave girl ate and died.”--_Her
Majesty’s Tower_, by Hepworth Dixon. Lond., 1869; i. p. 46.
[9] “This yeare, the 17th of March, was boyled in Smithfield one
Margaret Davie, a mayden, which had pouysoned 3 householdes that she
dwelled in. One being her mistress, which dyed of the same, and one
Darington and his wyfe, which she also dwelled with in Coleman Street,
which dyed of the same, and also one Tinleys, which dyed also of the
same.”--Wriotherley’s _Chronicle_, A.D. 1542.
§ 7. Two great criminal schools arose from the fifteenth to the
seventeenth centuries in Venice and Italy. The Venetian poisoners are of
earlier date than the Italian, and flourished chiefly in the fifteenth
century. Here we have the strange spectacle, not of the depravity of
individuals, but of the government of the State formally recognising
secret assassination by poison, and proposals to remove this or that
prince, duke, or emperor, as a routine part of their deliberations.
Still more curious and unique, the dark communings of “_the council of
ten_” were recorded in writing, and the number of those who voted for
and who voted against the proposed crime, the reason for the
assassination, and the sum to be paid, still exist in shameless black
and white. Those who desire to study this branch of secret history may
be referred to a small work by Carl Hoff, which gives a brief account of
what is known of the proceedings of the council. One example will here
suffice. On the 15th of December 1513 a Franciscan brother, John of
Ragubo, offered a selection of poisons, and declared himself ready to
remove any objectionable person out of the way. For the first successful
case he required a pension of 1500 ducats yearly, which was to be
increased on the execution of future services. The presidents, Girolando
Duoda and Pietro Guiarina, placed the matter before the “ten” on the 4th
of January 1514, and on a division (10 against 5) it was resolved to
accept so patriotic an offer, and to experiment first on the Emperor
Maximilian. The bond laid before the “ten” contained a regular
tariff--for the great Sultan 500 ducats, for the King of Spain 150
ducats, but the journey and other expenses were in each case to be
defrayed; the Duke of Milan was rated at 60, the Marquis of Mantua at
50, the Pope could be removed at 100 ducats. The curious offer thus
concludes:--“The farther the journey, the more eminent the man, the more
it is necessary to reward the toil and hardships undertaken, and the
heavier must be the payment.” The council appear to have quietly
arranged thus to take away the lives of many public men, but their
efforts were only in a few cases successful. When the deed was done, it
was registered by a single marginal note, “_factum_.”
What drugs the Venetian poisoners used is uncertain. The Italians
became notorious in the sixteenth and seventeenth centuries for their
knowledge of poisons, partly from the deeds of Toffana and others, and
partly from the works of J. Baptista Porta, who wrote a very
comprehensive treatise, under the title of _Natural Magic_,[10] and
managed to slide into the text, in the sections on cooking (_De Re
Coquinaria_, lib. xiv.), a mass of knowledge as to the preparation of
poisons. There are prescriptions that little accord with the title,
unless indeed the trades of cook and poisoner were the same. He gives a
method of drugging wine with belladonna root, for the purpose of making
the loaded guest loathe drink; he also gives a list of solanaceous
plants, and makes special mention of nux vomica, aconite, veratrum, and
mezereon. Again, in the section (_De Ancupio_, lib. xv.) he gives a
recipe for a very strong poison which he calls “_venenum lupinum_;” it
is to be made of the powdered leaves of _Aconitum lycoctonum_, _Taxus
baccata_, powdered glass, caustic lime, sulphide of arsenic, and bitter
almonds, the whole to be mixed with honey, and made into pills the size
of a hazel-nut.
[10] J. Bapt. Porta, born 1537, died 1615. _Neapolitani Magiæ
Naturalis._ Neapoli, 1589.
In the section _De Medicis Experimentis_ he gives a process to poison a
sleeping person: the recipe is curious, and would certainly not have the
intended effect. A mixture of hemlock juice, bruised datura, stramonium,
belladonna, and opium is placed in a leaden box with a perfectly fitting
cover, and fermented for several days; it is then opened under the nose
of the sleeper. Possibly Porta had experimented on small animals, and
had found that such matters, when fermented, exhaled enough carbonic
acid gas to kill them, and imagined, therefore, that the same thing
would happen if applied to the human subject. However this may be, the
account which Porta gives of the effects of the solanaceous plants, and
the general tone of the work, amply prove that he was no theorist, but
had studied practically the actions of poisons.
The iniquitous Toffana (or Tophana) made solutions of arsenious acid of
varying strength, and sold these solutions in phials under the name of
“_Acquetta di Napoli_” for many years. She is supposed to have poisoned
more than 600 persons, among whom were two Popes--viz., Pius III. and
Clement XIV. The composition of the Naples water was long a profound
secret, but is said to have been known by the reigning Pope and by the
Emperor Charles VI. The latter told the secret to Dr Garelli, his
physician, who, again, imparted the knowledge to the famous Friedrich
Hoffman in a letter still extant. Toffana was brought to justice in
1709, but, availing herself of the immunity afforded by convents,
escaped punishment, and continued to sell her wares for twenty years
afterwards. When Kepfer[11] was in Italy he found her in a prison at
Naples, and many people visited her, as a sort of lion (1730). With the
_Acqua Toffana_, the “_Acquetta di Perugia_” played at the same time its
part. It is said to have been prepared by killing a hog, disjointing the
same, strewing the pieces with white arsenic, which was well rubbed in,
and then collecting the juice which dropped from the meat; this juice
was considered far more poisonous than an ordinary solution of arsenic.
The researches of Selmi on compounds containing arsenic, produced when
animal bodies decompose in arsenical fluids, lend reason and support to
this view; and probably the juice would not only be very poisonous, but
act in a different manner, and exhibit symptoms different from those of
ordinary arsenical poisoning. Toffana had disciples; she taught the art
to Hieronyma Spara, who formed an association of young married women
during the popedom of Alexander VII.; these were detected on their own
confession.[12]
[11] Kepfer’s _Travels_. Lond., 1758.
[12] Le Bret’s _Magazin zu Gebrauche der Staat u. Kirchen-Geschichte_,
Theil 4. Frankfort and Leipzig, 1774.
Contemporaneously with Toffana, another Italian, Keli, devoted himself
to similar crimes. This man had expended much as an adept searching for
the philosopher’s stone, and sought to indemnify himself by entering
upon what must have been a profitable business. He it was who instructed
M. de St. Croix in the properties of arsenic; and St. Croix, in his
turn, imparted the secret to his paramour, Madame de Brinvilliers. This
woman appears to have been as cold-blooded as Toffana; she is said to
have experimented on the patients at the Hôtel Dieu, in order to
ascertain the strength of her powders, and to have invented “les poudres
de succession.” She poisoned her father, brothers, sister, and others of
her family; but a terrible fate overtook both her and St. Croix. The
latter was suffocated by some poisonous matters he was preparing, and
Madame de Brinvilliers’ practices having become known, she was obliged
to take refuge in a convent. Here she was courted by a police officer
disguised as an abbé, lured out of the convent, and, in this way brought
to justice, was beheaded[13] and burnt near Nôtre Dame, in the middle
of the reign of Louis XIV.[14]
[13] The Marchioness was imprisoned in the Conciergerie and tortured.
Victor Hugo, describing the rack in that prison, says, “The Marchioness
de Brinvilliers was stretched upon it stark naked, fastened down, so to
speak, quartered by four chains attached to the four limbs, and there
suffered the frightful extraordinary torture by water,” which caused her
to ask “How are you going to contrive to put that great barrel of water
in this little body?”--_Things seen by Victor Hugo_, vol. i.
The water torture was this:--a huge funnel-like vessel was fitted on to
the neck, the edge of the funnel coming up to the eyes; on now pouring
water into the funnel so that the fluid rises above the nose and mouth,
the poor wretch is bound to swallow the fluid or die of suffocation; if
indeed the sufferer resolve to be choked, in the first few moments of
unconsciousness the fluid is swallowed automatically, and air again
admitted to the lungs; it is therefore obvious that in this way
prodigious quantities of fluid might be taken.
[14] For the court of poisoners (_chambre ardente_) and the histories of
St. Croix, De Brinvilliers, the priest Le Sage, the women La Voisin, and
La Vigoureux, the reader may be referred to Voltaire’s _Siècle de Louis
XIV._, Madame de Sévigné’s _Lettres_, Martinière’s _Hist. de la Règne de
Louis XIV._, Strutzel, _De Venenis_, &c.
The numerous attempts of the Italian and Venetian poisoners on the lives
of monarchs and eminent persons cast for a long time a cloud over regal
domestic peace. Bullets and daggers were not feared, but in their place
the dish of meat, the savoury pasty, and the red wine were regarded as
possible carriers of death. No better example of this dread can be found
than, at so late a period as the reign of Henry VII.,[15] the
extraordinary precautions thought necessary for preserving the infant
Prince of Wales.
[15] Henry VIII., at one time of his life, was (or pretended to be)
apprehensive of being poisoned; it was, indeed, a common belief of his
court that Anne Boleyn attempted to dose him. “The king, in an interview
with young Prince Henry, burst into tears, saying that he and his sister
(meaning the Princess Mary) might thank God for having escaped from the
hands of that accursed and venomous harlot, who had intended to poison
them.”--_A Chronicle of England during the Reign of the Tudors_, by W.
J. Hamilton. Introduction, p. xxi.
“No person, of whatsoever rank, except the regular attendants in the
nursery, should approach the cradle, except with an order from the
king’s hand. The food supplied to the child was to be largely
‘_assayed_,’ and his clothes were to be washed by his own servants, and
no other hand might touch them. The material was to be submitted to all
tests. The chamberlain and vice-chamberlain must be present, morning and
evening, when the prince was washed and dressed, and nothing of any kind
bought for the use of the nursery might be introduced until it was
washed and perfumed. No person, not even the domestics of the palace,
might have access to the prince’s rooms except those who were specially
appointed to them, nor might any member of the household approach
London, for fear of their catching and conveying infection.”[16]
[16] Froude’s _History of England_, vol. iii. p. 262.
However brief and imperfect the foregoing historical sketch of the part
that poison has played may be, it is useful in showing the absolute
necessity of a toxicological science--a science embracing many branches
of knowledge. If it is impossible now for Toffanas, Locustas, and other
specimens of a depraved humanity to carry on their crimes without
detection; if poison is the very last form of death feared by eminent
political persons; it is not so much owing to a different state of
society, as to the more exact scientific knowledge which is applied
during life to the discrimination of symptoms, distinguishing between
those resulting from disease and those due to injurious substances, and
after death to a highly developed pathology, which has learned, by
multiplied observations, all the normal and abnormal signs in tissues
and organs; and, finally, to an ever-advancing chemistry, which is able
in many instances to separate and detect the hurtful and noxious thing,
although hid for months deep in the ground.
II.--Growth and Development of the Modern Methods of Chemically
Detecting Poisons.
§ 8. The history of the detection of poisons has gone through several
phases. The first phase has already been incidentally touched
upon--_i.e._, detection by antecedent and surrounding circumstances,
aided sometimes by experiments on animals. If the death was sudden, if
the post-mortem decomposition was rapid, poison was indicated: sometimes
a portion of the food last eaten, or the suspected thing, would be given
to an animal; if the animal also died, such accumulation of proof would
render the matter beyond doubt. The modern toxicologists are more
sceptical, for even the last test is not of itself satisfactory. It is
now known that meat may become filled with bacilli and produce rapid
death, and yet no poison, as such, has been added.
In the next phase, the doctors were permitted to dissect, and to
familiarise themselves with pathological appearances. This was a great
step gained: the apoplexies, heart diseases, perforations of the
stomach, and fatal internal hæmorrhages could no longer be ascribed to
poison. If popular clamour made a false accusation, there was more
chance of a correct judgment. It was not until the end of the eighteenth
and the beginning of the present century, however, that chemistry was
far enough advanced to test for the more common mineral poisons; the
modern phase was then entered on, and toxicology took a new departure.
§ 9. From the treatise of Barthélémy d’Anglais[17] in the thirteenth
century (in which he noticed the poisonous properties of quicksilver
vapour), up to the end of the fifteenth century, there are numerous
treatises upon poison, most of which are mere learned compilations, and
scarcely repay perusal. In the sixteenth century, there are a few works,
such, for example, as Porta, which partook of the general advancement of
science, and left behind the stereotyped doctrine of the old classical
schools.[18]
[17] _De Rerum Proprietaribus._
[18] In the sixteenth century it was not considered proper to write upon
poisons. Jerome Cardan declared a poisoner worse than a brigand, “and
that is why I have refused not only to teach or experiment on such
things, but even to know them.”--_J. Cardan: De Subtilitate_. Basel,
1558.
In the seventeenth century the Honourable Robert Boyle made some shrewd
observations, bearing on toxicology, in his work on “The usefulness of
Natural Philosophy,” &c.: Oxford, 1664. Nicolas L’Emery also wrote a
_Cours de Chimie_,--quite an epitome of the chemical science of the
time.[19]
[19] _Cours de Chimie, contenant la manière de faire les opérations qui
sont en usage dans la Médecine._ Paris, 1675.
In the eighteenth century still further advances were made. Richard Mead
published his ingenious _Mechanical Theory of Poisons_. Great chemists
arose--Stahl, Marggraf, Brandt, Bergmann, Scheele, Berthollet,
Priestley, and lastly, Lavoisier--and chemistry, as a science, was born.
Of the chemists quoted, Scheele, in relation to toxicology, stands
chief. It was Scheele who discovered prussic acid,[20] without, however,
noting its poisonous properties; the same chemist separated oxalic acid
from sorrel,[21] and made the important discovery that arsenic united
with hydrogen, forming a fœtid gas, and, moreover, that this gas could
be decomposed by heat.[22] From this observation, a delicate test for
arsenic was afterwards elaborated, which for the first time rendered the
most tasteless and easily administered poison in the whole world at once
the easiest of detection. The further history of what is now called
“Marsh’s Test” is as follows:--
[20] _Opuscula Chemica_, vol. ii. pp. 148-174.
[21] _De Terra Rhubarbi et Acido Acetosellæ._ _Nova Acta Acad. Veg.
Sued. Anni_, 1784. _Opuscula Chemica_, vol. ii. pp. 187-195.
Bergmann first described oxalic acid as obtained by the oxidation of
saccharine bodies; but Scheele recognised its identity with the acid
contained in sorrel.
[22] _Mémoires de Scheele_, t. i., 1775.
§ 10. Proust[23] observed that a very fœtid hydrogen gas was disengaged
when arsenical tin was dissolved in hydrochloric acid, and that arsenic
was deposited from the inflamed gas on cold surfaces which the flame
touched. Trommsdorff next announced, in 1803, that when arsenical zinc
was introduced into an ordinary flask with water and sulphuric acid, an
arsenical hydrogen was disengaged; and if the tube was sufficiently
long, arsenic was deposited on its walls.[24] Stromeyer, Gay-Lussac,
Thénard, Gehlen, and Davy later studied this gas, and Serullas in 1821
proposed this reaction as a toxicological test. Lastly, in 1836, Marsh
published his Memoir.[25] He elaborated a special apparatus of great
simplicity, developed hydrogen by means of zinc and sulphuric acid,
inflamed the issuing gas, and obtained any arsenic present as a metal,
which could be afterwards converted into arsenious acid, &c.
[23] Proust, _Annales de Chimie_, t. xxviii., 1798.
[24] _Nicholson’s Journal_, vol. vi.
[25] “Description of a New Process of Separating Small Quantities of
Arsenic from Substances with which it is mixed.” _Ed. New. Phil.
Journal_, 1836.
This brief history of the so-called “Marsh’s Test” amply shows that
Marsh was not the discoverer of the test. Like many other useful
processes, it seems to have been evolved by a combination of many minds.
It may, however, be truly said that Marsh was the first who perfected
the test and brought it prominently forward.
§ 11. Matthieu Joseph Bonaventura Orfila must be considered the father
of modern toxicology. His great work, _Traité de Toxicologie_, was first
published in 1814, and went through many editions. Orfila’s chief merit
was the discovery that poisons were absorbed and accumulated in certain
tissues--a discovery which bore immediate fruit, and greatly extended
the means of seeking poisons. Before the time of Orfila, a chemist not
finding anything in the stomach would not have troubled to examine the
liver, the kidney, the brain, or the blood. The immense number of
experiments which Orfila undertook is simply marvellous. Some are of
little value, and teach nothing accurately as to the action of
poisons--as, for example, many of those in which he tied the gullet in
order to prevent vomiting, for such are experiments under entirely
unnatural conditions; but there are still a large number which form the
very basis of our pathological knowledge.
Orfila’s method of experiment was usually to take weighed or measured
quantities of poison, to administer them to animals, and then after
death--first carefully noting the changes in the tissues and organs--to
attempt to recover by chemical means the poison administered. In this
way he detected and recovered nearly all the organic and inorganic
poisons then known; and most of his processes are, with modifications
and improvements, in use at the present time.[26]
[26] Orfila’s chief works are as follows:--
_Traité de Toxicologie._ 2 vols. 8vo. Paris, 1814.
_Leçons de Chimie, appliquées à la Méd. Pratique._ 16mo. Brussels, 1836.
_Mémoire sur la Nicotine et la Conicine._ Paris, 1851.
_Leçons de la Méd. Légale._ 8vo. Paris, 1821.
_Traité des Exhumations Juridiques, et Considérations sur les Changemens
Physiques que les Cadavres éprouvent en se pourrissant._ 2 tom. Paris,
1831.
§ 12. The discovery of the alkaloids at the commencement of this century
certainly gave the poisoner new weapons; yet the same processes
(slightly modified) which separated the alkaloids from plants also
served to separate them from the human body. In 1803 Derosne discovered
narcotine and morphine, but he neither recognised the difference between
these two substances, nor their basic properties. Sertürner from 1805
devoted himself to the study of opium, and made a series of discoveries.
Robiquet, in 1807, recognised the basic characters of narcotine. In 1818
Pelletier and Caventou separated strychnine; in 1819 brucine; and in the
same year delphinine was discovered simultaneously by Brande, Lassaigne,
and Feneuille. Coniine was recognised by Giesecke in 1827, and in the
following year, 1828, nicotine was separated by Reimann and Posselt. In
1832 Robiquet discovered codeine; and in 1833 atropine, aconitine, and
hyoscyamine were distinguished by Geiger and Hesse. Since then, every
year has been marked by the separation of some new alkaloid, from either
animal or vegetable substances. So many workers in different countries
now began to study and improve toxicology, that it would exceed the
limits and be foreign to the scope of this treatise to give even a brief
_résumé_ of their labours. It may, notwithstanding, be useful to append
a short bibliography of the chief works on toxicology of the present
century.
