secondary factors in their development. Actual sensations, it seems to me, serve only to bring to the service one set of virtualities rather than another; a sentient, intelligent, active being is a tangled skein of innumerable threads, some of which, and not others, will be drawn out by the events of life. This it is that marks out the precise work, limits the power, but at the same time encourages all the pretensions of educators. If all is not present in all, as Jacolot asserted, who can say what is and what is not present in a young animal or a young child?
I placed Mitis on a foot-warmer, the contact with which produced two or three nervous tremblings, somewhat similar to slight shiverings; he seemed pleased, however, and stretched himself out on the warm surface, with his eyes half-closed, as if going to sleep. Afterwards I placed Riquet there; he went through the same trembling movements, but then proceeded with an inspection with his muzzle—scenting or feeling, I do not know which, the article on which he had been deposited. He then gently stretched out a paw and laid himself down flat, the contact with the warm surface inducing sleep, by reason of the familiar associations between the like sensation of warmth experienced on his mother's breast and the instinctive need of sleep.
