Dr. Mott.—Before I was intimately associated with lunacy I was astonished to find in my hospital experience that nervous diseases were so frequently due to syphilis. I therefore adopted the treatment of giving mercury and iodide in all doubtful cases. In regard to general paralysis, I agree at first with those authorities which believe that syphilis had little to do with it; but careful examination of the patients and postmortem investigations convinced me that syphilis plays an important rôle in this disease.
