ABSTRACT

The study conducted by Dr. Berry and his associates has consisted of the correlation of clinical observations with physiologic and anatomic evidence. He has compared the brains of idiots, imbeciles, moral defectives and feebleminded persons with those of normal persons. He has compared them as to actual size by the brain product method, he has compared them as to weights of the right cerebral hemisphere and he has compared the planimeter cortical areas as determined on the flat by dioptrographic tracings. He has also compared as to morphologic changes grossly and microscopically the brains of feeble-minded persons with those of normal persons.

In determining the actual size of the brain by the brain product method, he multiplied the length by the breadth and the height of the brain by dioptrographic tracings and for practical purposes used the same measurements on the head and assumed that the proportion of brain size
