EUGENE RIGGS, A.M., M.D. ST. PAUL T he cl inical history of syphili s with its therapy is in the process of making, and is greatly in need of restat ing. Especially is this true of nervous syphilis. T he report of many investigators are so incomplete, so lackin g in scientific accuracy, as to cloud their findings and give rise to great confusion and difference of opini on. Paucity of experience, the failure to follow lines of procedure marked out by previous well-known and competent investigators, substituting therefor per sonal and theoretical mod ifications, are all important factors in the production of this deplorable condition. There are but few Noguchis or Marinescos, few Swifts and E llises. There must be mutual endeaYor; a cooperation of effort, so to speak, along definite lines among those in terested in the therapy of syphilitic nervous diseases, if order is to come out of chaos and definite and reli able data be obtained.
