them of one shape and two of another. In other words, of the possibilities contributed by the father and mother, some are taken and some are left in the case of any one child. Further, different children will represent different selections from amongst the germinal elements. Mendelism, by the way, is especially concerned to find out the law according to which the different types of organization are distributed between the offspring. Each child, meanwhile, is a unique individual, a living whole with an organization of its very own. This means that its constituent elements form a system. They stand to each other in relations of mutual support. In short, life is possible because there is balance.

This general state of balance, however, is able to go along with a lot of special balancings that seem largely independent of each other. It is important to remember this when we come a little later on to consider the instincts. All sorts of lesser systems prevail within the larger system represented by the individual organism. It is just as if within the state with its central government there were a number of county councils, municipal corporations, and so on, each of them enjoying a certain measure of self-government on its own account. Thus we can see in a very general way how it is that so much variation is possible. The selective organization, which from amongst the germinal elements precipitates ever so many and different forms of fresh life, is so loose and elastic that a working arrangement between the parts can be reached in all sorts of directions. The lesser systems are so far self-governing that they can be trusted to get along in almost any combination; though of course some combinations are naturally stronger and more stable than the rest, and hence tend to outlast them, or, as the phrase goes, to be preserved by natural selection.

It is time to take account of the principle of natural selection. We have done with the subject of variation. Whether use and disuse have helped to shape the fresh forms of life, or whether these are purely spontaneous combinations that have come into being on what we are pleased to call their own account, at any rate let us take them as given. What happens now? At this point begins the work of natural selection. Darwin's great achievement was to formulate this law; though it is only fair to add that it was discovered by A.R. Wallace at the same moment. Both of them get the first hint of it from Malthus. This English clergyman, writing about half a century earlier, had shown that the growth of population is apt very considerably to outstrip the development of food-supply; whereupon natural checks such as famine or war must, he argued, ruthlessly intervene so as to redress the balance. Applying these considerations to the plant and animal kingdoms at large, Darwin and Wallace perceived that, of the multitudinous forms of life thrust out upon the world to get a livelihood as best they could, a vast quantity must be weeded out. Moreover, since they vary exceedingly in their type of organization, it seemed reasonable to suppose that, of the competitors, those who were innately fitted to make the best of the ever-changing circumstances would outlive the rest. An appeal to the facts fully bore out this hypothesis. It must not, indeed, be thought that all the weeding out which goes on favours the fittest. Accidents will always happen. On the whole, however, the type that is most at home under the surrounding conditions, it may be because it is more complex, or it may be because it is of simpler organization, survives the rest.

Now to survive is to survive to breed. If you live to eighty, and have no children, you do not survive in the biological sense; whereas your neighbour who died at forty may survive in a numerous progeny. Natural selection is always in the last resort between individuals; because individuals are alone competent to breed. At the same time, the reason for the individual's survival may lie very largely outside him. Amongst the bees, for instance, a non-working type of insect survives to breed because the sterile workers do their duty by the hive. So, too, that other social animal, man, carries on the race by means of some whom others die childless in order to preserve. Nevertheless, breeding being a strictly individual and personal affair, there is always a risk lest a society, through spending its best too freely, end by recruiting its numbers from those in whom the engrained capacity to render social service is weakly developed. To rear a goodly family must always be the first duty of unselfish people; for otherwise the spirit of unselfishness can hardly be kept alive the world.

Enough about heredity as a condition of evolution. We return, with a better chance of distinguishing them, to the consideration of the special effects that it brings about. It was said just now that heredity is the stiffening in human nature, a stiffening bound up with a more or less considerable offset of plasticity. Now clearly it is in some sense true that the child's whole nature, its modicum of plasticity included, is handed on from its parents. Our business in this chapter, however, is on the whole to put out of our thoughts this plastic side of the inherited life-force. The more or less rigid, definite, systematized characters—these form the hereditary factor, the race. Now none of these are ever quite fixed. A certain measure of plasticity has to be counted in as part of their very nature. Even in the bee, with its highly definite instincts, there is a certain flexibility bound up with each of these; so that, for instance, the inborn faculty of building up the comb regularly is modified if the hive happens to be of an awkward shape. Yet, as compared with what remains over, the characters that we are able to distinguish as racial must show fixity. Unfortunately, habits show fixity too. Yet habits belong to the plastic side of our nature; for, in forming a habit, we are plastic at the start, though hardly so once we have let ourselves go. Habits, then, must be discounted in our search for the hereditary bias in our lives. It is no use trying to disguise the difficulties attending an inquiry into race.

These difficulties notwithstanding, in the rest of this chapter let us consider a few of what are usually taken to be racial features of man. As before, the treatment must be illustrative; we cannot work through the list. Further, we must be content with a very rough division into bodily and mental features. Just at this point we shall find it very hard to say what is to be reckoned bodily and what mental. Leaving these niceties to the philosophers, however, let us go ahead as best we can.

Oh for an external race-mark about which there could be no mistake! That has always been a dream of the anthropologist; but it is a dream that shows no signs of coming true. All sorts of tests of this kind have been suggested. Cranium, cranial sutures, frontal process, nasal bones, eye, chin, jaws, wisdom teeth, hair, humerus, pelvis, the heart-line across the hand, calf, tibia, heel, colour, and even smell—all these external signs, as well as many more, have been thought, separately or together, to afford the crucial test of a man's pedigree. Clearly I cannot here cross-examine the entire crowd of claimants, were I even competent to do so. I shall, therefore, say a few words about two, and two only, namely, head-form and colour.

I believe that, if the plain man were to ask himself how, in walking down a London street, he distinguished one racial type from another, he would find that he chiefly went by colour. In a general way he knows how to make allowance for sunburn and get down to the native complexion underneath. But, if he went off presently to a museum and tried to apply his test to the pre-historic men on view there, it would fail for the simple reason that long ago they left their skins behind them. He would have to get to work, therefore, on their bony parts, and doubtless would attack the skulls for choice. By considering head-form and colour, then, we may help to cover a certain amount of the ground, vast as it is. For remember that anthropology in this department draws no line between ancient and modern, or between savage and civilized, but tries to tackle every sort of man that comes within its reach.

Head-shape is really a far more complicated thing to arrive at for purposes of comparison than one might suppose. Since no part of the skull maintains a stable position in regard to the rest, there can be no fixed standard of measurement, but at most a judgment of likeness or unlikeness founded on an averaging of the total proportions. Thus it comes about that, in the last resort, the impression of a good expert is worth in these matters a great deal more than rows of figures. Moreover, rows of figures in their turn take a lot of understanding. Besides, they are not always easy to get. This is especially the case if you are measuring a live subject. Perhaps he is armed with a club, and may take amiss the use of an instrument that has to be poked into his ears, or what not. So, for one reason or another, we have often to put up with that very unsatisfactory single-figure description of the head-form which is known as the cranial index. You take the greatest length and greatest breadth of the skull, and write down the result obtained by dividing the former into the latter when multiplied by 100. Medium-headed people have an index of anything between 75 and 80. Below that figure men rank as long-headed, above it as round-headed. This test, however, as I have hinted, will not by itself carry us far. On the other hand, I believe that a good judge of head-form in all its aspects taken together will generally be able to make a pretty shrewd guess as to the people amongst whom the owner of a given skull is to be placed.

Unfortunately, to say people is not to say race. It may be that a given people tend to have a characteristic head-form, not so much because they are of common breed, as because they are subjected after birth, or at any rate, after conception, to one and the same environment. Thus some careful observations made recently by Professor Boas on American immigrants from various parts of Europe seem to show that the new environment does in some unexplained way modify the head-form to a remarkable extent. For example, amongst the East European Jews the head of the European-born is shorter and wider than that of the American-born, the difference being even more marked in the second generation of the American-born. At the same time, other European nationalities exhibit changes of other kinds, all these changes, however, being in the direction of a convergence towards one and the same American type. How are we to explain these facts, supposing them to be corroborated by more extensive studies? It would seem that we must at any rate allow for a considerable plasticity in the head-form, whereby it is capable of undergoing decisive alteration under the influences of environment; not, of course, at any moment during life, but during those early days when the growth of the head is especially rapid. The further question whether such an acquired character can be transmitted we need not raise again. Before passing on, however, let this one word to the wise be uttered. If the skull can be so affected, then what about the brain inside it? If the hereditarily long-headed
