M. Taine's very interesting account of the mental development of an infant, translated in the last number of (p. 252), has led me to look over a diary which I kept thirty-seven years ago with respect to one of my own infants. I had excellent opportunities for close observation, and wrote down at once whatever was observed. My chief object was expression, and my notes were used in my book on this subject; but as I attended some little interest in comparison with those by M. Taine, and with others which hereafter no doubt will be made. I feel sure, from what I have seen with my own infants, that the period of development of the several faculties will be found to differ considerably in different infants. During the first seven days various reflex actions, namely sneezing, hickuping, yawning, stretching, and of course sucking and screaming, were well performed by my infant. On the seventh day, I touch the naked sole of his foot with a bit of paper, and he jerked it away, curling at the same time his toes, like a much older child when tickled.

At this time, though so early, it seemed clear to me that a warm soft hand applied to his face excited a wish to suck.
