changes in the conditions of reproduction; the suggestive factors vary. The influence on imagery of general ideas, of emotion, and of the general setting of mental life at the time of reproduction, is very great.1 Whether a point is reached at which reproduction is impossible, it is difficult to prove. We might expect complete decay here as with other forms of life, that a function might, after lapse of time, having fallen into disuse, be incapable of being continued; an item of knowledge would then be forgotten beyond possibility of recall. In the end all questions as to the nature of a memoryimage must be tested by experiment. This essay only purports to be a discussion of theories. It will have served its turn, if it has shown how far reaching in its consequences may be this question which lies in the heart of the memory problem, the nature of a memory-image. 1 Cf.
