And as the diagrams became more complicated, they figured and suggested the possibility of lesions which, just because they were more diverse, were more special and more simple, the complication of the diagram being due precisely to that dissociation of centres which had at first been confounded. Experience, however, was far from justifying the theory at this point, since it nearly always showed, in partial and diverse combinations, several of those simple psychical
