In the large experience I have had of sorting photographs, literally

by the thousand, while making experiments with composites, I have

been struck by certain general impressions. The consumptive patients

consisted of many hundred cases, including a considerable proportion

of very ignoble specimens of humanity. Some were scrofulous and

misshapen, or suffered from various loathsome forms of inherited

disease; most were ill nourished. Nevertheless, in studying their

portraits the pathetic interest prevailed, and I returned day after

day to my tedious work of classification, with a liking for my

materials. It was quite otherwise with the criminals. I did not

adequately appreciate the degradation of their expressions for some

time; at last the sense of it took firm hold of me, and I cannot now

handle the portraits without overcoming by an effort the aversion

they suggest.

I am sure that the method of composite portraiture opens a fertile

field of research to ethnologists, but I find it very difficult to

do much single-handed, on account of the difficulty of obtaining the

necessary materials. As a rule, the individuals must be specially

photographed. The portraits made by artists are taken in every

conceivable aspect and variety of light and shade, but for the

purpose in question the aspect and the shade must be the same

throughout. Group portraits would do to work from, were it not for

the strong out-of-door light under which they are necessarily taken,

which gives an unwonted effect to the expression of the faces. Their

scale also is too small to give a sufficiently clear picture when

enlarged. I may say that the scale of the portraits need not be

uniform, as my apparatus enlarges or reduces as required, at the

same time that it superposes the images; but the portraits of the

heads should never be less than twice the size of that of the Queen

on a halfpenny piece.

I heartily wish that amateur photographers would seriously take up

the subject of composite portraiture as applied to different

sub-types of the varying races of men. I have already given more

time to perfecting the process and experimenting with it than I can

well spare.

BODILY QUALITIES.

The differences in the bodily qualities that are the usual subjects

of anthropometry are easily dealt with, and are becoming widely

registered in many countries. We are unfortunately destitute of

trustworthy measurements of Englishmen of past generations to enable

us to compare class with class, and to learn how far the several

sections of the English nation may be improving or deteriorating. We

shall, however, hand useful information concerning our own times to

our successors, thanks principally to the exertions of an

Anthropometric Committee established five years ago by the British

Association, who have collected and partly classified and published

a large amount of facts, besides having induced several institutions,

such as Marlborough College, to undertake a regular system of

anthropometric record. I am not, however, concerned here with the

labours of this committee, nor with the separate valuable

publications of some of its members, otherwise than in one small

particular which appears to show that the English population as a

whole, or perhaps I should say the urban portion of it, is in some

sense deteriorating. It is that the average stature of the older

persons measured by or for the committee has not been found to

decrease steadily with their age, but sometimes the reverse.[1] This

contradicts observations made on the heights of the same men at

different periods, whose stature after middle age is invariably

reduced by the shrinking of the cartilages. The explanation offered

was that the statistical increase of stature with age should be

ascribed to the survival of the more stalwart. On reconsideration, I

am inclined to doubt the adequacy of the explanation, and partly to

account for the fact by a steady, slight deterioration of stature in

successive years; in the urban population owing to the conditions of

their lives, and in the rural population owing to the continual

draining away of the more stalwart of them to the towns.

It cannot be doubted that town life is harmful to the town population.

I have myself investigated its effect on fertility (see Appendix B),

and found that taking on the one hand a number of rural parishes,

and on the other hand the inhabitants of a medium town, the former

reared, nearly twice as many adult grandchildren as the latter. The

vital functions are so closely related that an inferiority in the

production of healthy children very probably implies a loss of

vigour generally, one sign of which is a diminution of stature.

Though the bulk of the population may deteriorate, there are many

signs that the better housed and fed portion of it improves. In the

earlier years of this century the so-called manly sports of boxing

and other feats of strength ranked high among the national amusements.

A man who was [1] successful in these became the hero of a large and

demonstrative circle of admirers, and it is to be presumed that the

best boxer, the best pedestrian, and so forth, was the best adapted

to succeed, through his natural physical gifts. If he was not the

most gifted man in those respects in the whole kingdom, he was

certainly one of the most gifted of them. It therefore does no

injustice to the men of that generation to compare the feats of

their foremost athletes with those of ours who occupy themselves in

the same way. The comparison would probably err in their favour,

because the interest in the particular feats in which our

grandfathers and great-grandfathers delighted are not those that

chiefly interest the present generation, and notwithstanding our

increased population, there are fewer men now who attempt them. In

the beginning of this century there were many famous walking matches,

and incomparably the best walker was Captain Barclay of Ury. His

paramount feat, which was once very familiar to the elderly men of

the present time, was that of walking a thousand miles in a thousand

hours, but of late years that feat has been frequently equalled and

overpassed. I am willing to allow much influence to the modern

conditions of walking under shelter and subject to improved methods

of training (Captain Barclay himself originated the first method,

which has been greatly improved since his time); still the fact

remains that in executing this particular feat, the athletes of the

present day are more successful than those who lived some eighty

years ago. I may be permitted to give an example bearing on the

increased stature of the better housed and fed portion of the nation,

in a recollection of my own as to the difference in height between

myself and my fellow-collegians at Trinity College, Cambridge, in

1840-4. My height is 5 feet 9-3/4 inches, and I recollect perfectly

that among the crowd of undergraduates I stood somewhat taller than

the majority. I generally looked a little downward when I met their

eyes. In later years, whenever I have visited Cambridge, I have

lingered in the ante-chapel and repeated the comparison, and now I

find myself decidedly shorter than the average of the students. I

have precisely the same kind of recollection and the same present

experience of the height of crowds of well-dressed persons. I used

always to get a fair view of what was going on over or between their

heads; I rarely can do so now.

[Footnote 1: _Trans. Brit. Assoc_., 1881, Table V., p. 242; and

remarks by Mr. Roberts, p. 235.]

The athletic achievements at school and college are much superior to

what they used to be. Part is no doubt due to more skilful methods

of execution, but not all. I cannot doubt that the more wholesome

and abundant food, the moderation in drink, the better cooking, the

warmer wearing apparel, the airier sleeping rooms, the greater

cleanliness, the more complete change in holidays, and the healthier

lives led by the women in their girlhood, who become mothers

afterwards, have a great influence for good on the favoured portion

of our race.

The proportion of weakly and misshapen individuals is not to be

estimated by those whom we meet in the streets; the worst cases are

out of sight. We should parade before our mind's eye the inmates of

the lunatic, idiot, and pauper asylums, the prisoners, the patients

in hospitals, the sufferers at home, the crippled, and the

congenitally blind, and that large class of more or less wealthy

persons who flee to the sunnier coasts of England, or expatriate

themselves for the chance of life. There can hardly be a sadder

sight than the crowd of delicate English men and women with narrow

chests and weak chins, scrofulous, and otherwise gravely affected,

who are to be found in some of these places. Even this does not tell

the whole of the story; if there were a conscription in England, we

should find, as in other countries, that a large fraction of the men

who earn their living by sedentary occupations are unfit for

military service. Our human civilised stock is far more weakly

through congenital imperfection than that of any other species of

animals, whether wild or domestic.

It is, however, by no means the most shapely or the biggest

personages who endure hardship the best. Some very shabby-looking

men have extraordinary stamina. Sickly-looking and puny residents in

towns may have a more suitable constitution for the special

conditions of their lives, and may in some sense be better knit and

do more work and live longer than much haler men imported to the

same locality from elsewhere. A wheel and a barrel seem to have the

flimsiest possible constitutions; they consist of numerous separate

pieces all oddly shaped, which, when lying in a heap, look

hopelessly unfitted for union; but put them properly together,

compress them with a tire in the one case and with hoops in the other,

and a remarkably enduring organisation will result. A wheel with a

ton weight on the top of it in the waggons of South Africa will jolt

for thousands of miles over stony, roadless country without

suffering harm; a keg of water may be strapped on the back of a

pack-ox or a mule, and be kicked off and trampled on, and be

otherwise misused for years, without giving way.

I do not propose to enter further into the anthropometric

differences of race, for the subject is a very large one, and this

book does not profess to go into detail. Its intention is to touch

on various topics more or less connected with that of the

cultivation of race, or, as we might call it, with "eugenic" [1]

questions, and to present the results of several of my own separate

investigations.

ENERGY.

Energy is the capacity for labour. It is consistent with all the

robust virtues, and makes a large practice of them possible. It is

the measure of fulness of life; the more energy the more abundance

of it; no energy at all is death; idiots are feeble and listless. In

the inquiries I made on the antecedents of men of science no points

came out more strongly than that the leaders of scientific thought

were generally gifted with remarkable energy, and that they had

[2] inherited the gift of it from their parents and grandparents. I

have since found the same to be the case in other careers.

[Footnote 2: That is, with questions bearing on what is termed in

Greek, _eugenes_, namely, good in stock, hereditarily endowed with

noble qualities. This, and the allied words, _eugeneia_, etc., are

equally applicable to men, brutes, and plants. We greatly want a

brief word to express the science of improving stock, which is by no

means confined to questions of judicious mating, but which,

especially in the case of man, takes cognisance of all influences

that tend in however remote a degree to give to the more suitable

races or strains of blood a better chance of prevailing speedily

over the less suitable than they otherwise would have had. The word

_eugenics_ would sufficiently express the idea; it is at least a

neater word and a more generalised one than _viriculture_, which I

once ventured to use.]

Energy is an attribute of the higher races, being favoured beyond

all other qualities by natural selection. We are goaded into

activity by the conditions and struggles of life. They afford

stimuli that oppress and worry the weakly, who complain and bewail,

and it may be succumb to them, but which the energetic man welcomes

with a good-humoured shrug, and is the better for in the end.

The stimuli may be of any description: the only important matter is

that all the faculties should be kept working to prevent their

perishing by disuse. If the faculties are few, very simple stimuli

will suffice. Even that of fleas will go a long way. A dog is

continually scratching himself, and a bird pluming itself, whenever

they are not occupied with food, hunting, fighting, or love. In

those blank times there is very little for them to attend to besides

their varied cutaneous irritations. It is a matter of observation

that well washed and combed domestic pets grow dull; they miss the

stimulus of fleas. If animals did not prosper through the agency of

their insect plagues, it seems probable that their races would long

since have been so modified that their bodies should have ceased to

afford a pasture-ground for parasites.

It does not seem to follow that because men are capable of doing

hard work they like it. Some, indeed, fidget and fret if they cannot

otherwise work off their superfluous steam; but on the other hand

there are many big lazy fellows who will not get up their steam to

full pressure except under compulsion. Again, the character of the

stimulus that induces hard work differs greatly in different persons;

it may be wealth, ambition, or other object of passion. The solitary

hard workers, under no encouragement or compulsion except their

sense of duty to their generation, are unfortunately still rare

among us.

It may be objected that if the race were too healthy and energetic

there would be insufficient call for the exercise of the pitying and

self-denying virtues, and the character of men would grow harder in

consequence. But it does not seem reasonable to preserve sickly

breeds for the sole purpose of tending them, as the breed of foxes

is preserved solely for sport and its attendant advantages. There is

little fear that misery will ever cease from the land, or that the

compassionate will fail to find objects for their compassion; but at

present the supply vastly exceeds the demand: the land is

overstocked and overburdened with the listless and the incapable.

In any scheme of eugenics, energy is the most important quality to

favour; it is, as we have seen, the basis of living action, and it

is eminently transmissible by descent.

SENSITIVITY.

The only information that reaches us concerning outward events

appears to pass through the avenue of our senses; and the more

perceptive the senses are of difference, the larger is the field

upon which our judgment and intelligence can act. Sensation mounts

through a series of grades of "just perceptible differences." It

starts from the zero of consciousness, and it becomes more intense

as the stimulus increases (though at a slower rate) up to the point

when the stimulus is so strong as to begin to damage the nerve

apparatus. It then yields place to pain, which is another form of

sensation, and which continues until the nerve apparatus is destroyed.

Two persons may be equally able just to hear the same faint sound,

and they may equally begin to be pained by the same loud sound, and

yet they may differ as to the number of intermediate grades of

sensation. The grades will be less numerous as the organisation is

of a lower order, and the keenest sensation possible to it will in

consequence be less intense. An artist who is capable of

discriminating more differences of tint than another man is not

necessarily more capable of seeing clearly in twilight, or more or

less intolerant of sunshine. A musician is not necessarily able to

hear very faint sounds, nor to be more startled by loud sounds than

others are. A mechanic who works hard with heavy tools and has rough

and grimy thumbs, insensible to very slight pressures, may yet have

a singularly discriminating power of touch in respect to the

pressures that he can feel.

The discriminative faculty of idiots is curiously low; they hardly

distinguish between heat and cold, and their sense of pain is so

obtuse that some of the more idiotic seem hardly to know what it is.

In their dull lives, such pain as can be excited in them may

literally be accepted with a welcome surprise. During a visit to

Earlswood Asylum I saw two boys whose toe-nails had grown into the

flesh and had been excised by the surgeon. This is a horrible

torture to ordinary persons, but the idiot lads were said to have

shown no distress during the operation; it was not necessary to hold

them, and they looked rather interested at what was being done.

[1] I also saw a boy with the scar of a severe wound on his wrist;

the story being that he had first burned himself slightly by accident,

and, liking the keenness of the new sensation, he took the next

opportunity of repeating the experience, but, idiot-like, he overdid

it.

The trials I have as yet made on the sensitivity of different

persons confirms the reasonable expectation that it would on the

whole be highest among the intellectually ablest. At first, owing to

my confusing the quality of which I am speaking with that of nervous

irritability, I fancied that women of delicate nerves who are

distressed by noise, sunshine, etc., would have acute powers of

discrimination. But this I found not to be the case. In morbidly

sensitive persons both pain and sensation are induced by lower

stimuli than in the healthy, but the number of just perceptible

grades of sensation between them is not necessarily different.

I found as a rule that men have more delicate powers of

discrimination than women, and the business experience of life seems

to confirm this view. The tuners of pianofortes are men, and so I

understand are the tasters of tea and wine, the sorters of wool, and

the like. These latter occupations are well salaried, because it is

of the first moment to the merchant that he should be rightly advised

on the real value of what he is about to purchase or to sell. If the

sensitivity of women were superior to that of men, the self-interest

of merchants would lead to their being [3] always employed; but as

the reverse is the case, the opposite supposition is likely to be

the true one.

[Footnote 3: See "Remarks on Idiocy," by E.W. Graham, M. D.,

_Medical Journal_, January 16, 1875.]

Ladies rarely distinguish the merits of wine at the dinner-table,

and though custom allows them to preside at the breakfast-table, men

think them on the whole to be far from successful makers of tea and

coffee.

Blind persons are reputed to have acquired in compensation for the

loss of their eyesight an increased acuteness in their other senses;

I was therefore curious to make some trials with my test apparatus,

which I will describe in the next chapter. I was permitted to do so

on a number of boys at a large educational blind asylum, but found

that, although they were anxious to do their best, their performances

were by no means superior to those of other boys. It so happened

that the blind lads who showed the most delicacy of touch and won

the little prizes I offered to excite emulation, barely reached the

mediocrity of the various sighted lads of the same age whom I had

previously tested. I have made not a few observations and inquiries,

and find that the guidance of the blind depends mainly on the

multitude of collateral indications to which they give much heed,

and not in their superior sensitivity to any one of them. Those who

see do not care for so many of these collateral indications, and

habitually overlook and neglect several of them. I am convinced also

that not a little of the popular belief concerning the sensitivity

of the blind is due to exaggerated claims on their part that have

not been verified. Two instances of this have fallen within my own

experience, in both of which the blind persons claimed to have the

power of judging by the echo of their voice and by certain other

feelings, the one when they were approaching objects, even though

the object was so small as a handrail, and the other to tell how far

the door of the room in which he was standing was open. I used all

the persuasion I could to induce each of these persons to allow me

to put their assertions to the test; but it was of no use. The one

made excuses, the other positively refused. They had probably the

same tendency that others would have who happened to be defective in

any faculty that their comrades possessed, to fight bravely against

their disadvantage, and at the same time to be betrayed into some

overvaunting of their capacities in other directions. They would be

a little conscious of this, and would therefore shrink from being

tested.

The power of reading by touch is not so very wonderful. A former

Lord Chancellor of England, the late Lord Hatherley, when he was

advanced in years, lost his eyesight for some time owing to a

cataract, which was not ripe to be operated on. He assured me that

he had then learned and practised reading by touch very rapidly.

This fact may perhaps also serve as additional evidence of the

sensitivity of able men.

Notwithstanding many travellers' tales, I have thus far been

unsuccessful in obtaining satisfactory evidence of any general large

superiority of the senses of savages over those of civilised men. My

own experience, so far as it goes, of Hottentots, Damaras, and some

other wild races, went to show that their sense discrimination was

not superior to those of white men, even as regards keenness of

eyesight. An offhand observer is apt to err by assigning to a single

cause what is partly due to others as well. Thus, as regards eyesight,

a savage who is accustomed to watch oxen grazing at a distance

becomes so familiar with their appearance and habits that he can

identify particular animals and draw conclusions as to what they are

doing with an accuracy that may seem to strangers to be wholly

dependent on exceptional acuteness of vision. A sailor has the

reputation of keen sight because he sees a distant coast when a

landsman cannot make it out; the fact being that the landsman

usually expects a different appearance to what he has really to look

for, such as a very minute and sharp outline instead of a large,

faint blur. In a short time a landsman becomes quite as quick as a

sailor, and in some test experiments[1] he was found on the average

to be distinctly the superior. It is not surprising that this should

be so, as sailors in vessels of moderate size have hardly ever the

practice of focussing their eyes sharply upon objects farther off

than the length of the vessel or the top of the mast, say at a

distance of fifty paces. The horizon itself as seen from the deck,

[4] and under the most favourable circumstances, is barely four

miles off, and there is no sharpness of outline in the intervening

waves. Besides this, the life of a sailor is very unhealthy, as

shown by his growing old prematurely, and his eyes must be much

tried by foul weather and salt spray.

[Footnote 4: Gould's _Military and Anthropological Statistics_, p.

530. New York, 1869.]

We inherit our language from barbarous ancestors, and it shows

traces of its origin in the imperfect ways by which grades of

difference admit of being expressed. Suppose a pedestrian is asked

whether the knapsack on his back feels heavy. He cannot find a reply

in two words that cover more varieties than (1) very heavy, (2)

rather heavy, (3) moderate, (4) rather light, (5) very light. I once

took considerable pains in the attempt to draw up verbal scales of

more than five orders of magnitude, using those expressions only

that every cultivated person would understand in the same sense; but

I did not succeed. A series that satisfied one person was not

interpreted in the same sense by another.

The general intention of this chapter has been to show that a

delicate power of sense discrimination is an attribute of a high race,

and that it has not the drawback of being necessarily associated

with nervous irritability.
