We have now to see whether experience verifies these three propositions.
I. The two forms of memory.—I study a lesson, and in order to learn it by heart I read it a first time, accentuating every line; I then repeat it a certain number of times. At each repetition there is progress; the words are more and more linked together, and at last make a continuous whole. When that moment comes, it is said that I know my lesson by heart, that it is imprinted on my memory.
I consider now how the lesson has been learnt, and picture to myself the successive phases of the process. Each several reading then recurs to me with its own individuality; I can see it again with the circumstances which attended it then and still form its setting. It is distinguished from those which preceded or followed it by the place which it occupied in time; in short, each reading stands out before my mind as a definite event in my history.

The memory of the lesson, which is remembered in the sense of learnt by heart, has all the marks of a habit. Like a habit, it is acquired by the repetition of the same effort. Like a habit, it demands first a decomposition and then a recom-
