child cannot eat, and cannot drink, but he can swallow as soon as he is born; and swallowing would appear (as we may remark in passing) to have been an earlier faculty of animal life than that of eating with teeth. The ease and unconsciousness with which we eat and drink is clearly attributable to practice; but a very little practice seems to go a long way--a suspiciously small amount of practice--as though somewhere or at some other time there must have been more practice than we can account for. We can very readily stop eating or drinking, and can follow our own action without difficulty in either process; but, as regards swallowing, which is the earlier habit, we have less power of self-analysis and control: when we have once committed ourselves beyond a certain point to swallowing, we must finish doing so,--that is to say, our control over the operation ceases. Also, a still smaller experience seems necessary for the acquisition of the power to swallow than appeared necessary in the case of eating; and if we get into a difficulty we choke, and are more at a loss how to become introspective than we are about eating and drinking.

Why should a baby be able to swallow--which one would have said was the more complicated process of the two--with so much less practice than it takes him to learn to eat? How comes it that he exhibits in the case of the more difficult operation all the phenomena which ordinarily accompany a more complete mastery and longer practice? Analogy would certainly seem to point in the direction of thinking that the necessary experience cannot have been wanting, and that, too, not in such a quibbling sort as when people talk about inherited habit or the experience of the race, which, without explanation, is to plain-speaking persons very much the same, in regard to the individual, as no experience at all, but bona fide in the child's own person.

Breathing, again, is an action acquired after birth, generally with some little hesitation and difficulty, but still acquired in a time seldom longer, as I am informed, than ten minutes or a quarter of an hour. For an ant which has to be acquired at all, there would seem here, as in the case of eating, to be a disproportion between, on the one hand, the intricacy of the process performed, and on the other, the shortness of the time taken to acquire the practice, and the ease and unconsciousness with which its exercise is continued from the moment of acquisition.

We observe that in later life much less difficult and intricate operations than breathing acquire much longer practice before they can be mastered to the extent of unconscious performance. We observe also that the phenomena attendant on the learning by an infant to breathe are extremely like those attendant upon the repetition of some performance by one who has done it very often before, but who requires just a little prompting to set him off, on getting which, the whole familiar routine presents
