Dr. E. E. Southard, Boston, read a paper entitled, "Data Concerning Delusions of Personality."[*] [*] Published in this number of the Journal, p. 241. DISCUSSION DR. SMITH ELY JELLIFFE, New York: Dr. Southard has heretofore launched us upon very large subjects. I can well recall in one of his previous communications the fascinating correlations drawn between structural changes and the character of the psychological signs. In dementia praecox particularly, he has shown us how auditory symptoms group about temporal atrophies and optical signs with the occipital and so forth and so on. He now proposes to thrust us into a larger and much more intricate sphere of activity as to the representation in the cortex of other changes which as he has described are inframicroscopical or inframacroscopical. In other words, there must be some type of correlation between the projection in the cerebral structure of the organ itself which is cerebrally represented and certain mental signs. If I see what Dr. Southard has been thinking about, we are certainly engaged in a very fascinating topic. It is well known from the standpoint of topographical cerebral correlation that the brain is nothing but a series of body symbols, as it were. Adler has entered this field and approaches the problem by saying that the inferior organ, liver, kidney, or what not, is related to a similar defective cerebral representation of the organ, thus introducing into the nemological mechanism the task of compensating for the defective structure. Dr. Southard wishes to try to map out these defects in the cerebral structures and thus reason backwards to the somatic inferiority. I confess he lifts me into ideal regions. Such stimuli are enjoyable and provocative of development. DR. TOM A. WILLIAMS, Washington, D. C: I conceive Dr. Southard's purpose somewhat differently from Dr. Jelliffe whose thought seems to be somewhat like that of Henry Head when he published his paper in reference to hallucinations, corresponding to various head zones in correspondence with different visceral areas and with special sense organs, eye, ear and so on. I have conceived Dr. Southard as being a direct chemical in line with Folius' pathology researches. If that is the case we have a great many clinical cases which might be underlined with his central thought.
