The sensory phenomena will varyalso, one side often showing moremarkedly than the other. Thereis hyperesthesia at about the levelof the lesion which is changed tovarious grades of anesthesia belowthe lesion.

Amer. Med. Assoc, 1914. LATERAL SCLEROSIS GROUP 351 Small tumors (cysts,etc.), intramedullary, sometimes extramedullary,cause typical dissociation symptoms with retention of epicritic tactilesensibility and loss of protopathic pain and thermal sensibility. The symptoms for localization of the tumor have already beendiscussed. Diagnosis. —- X-ray examination, spinal fluid examination, anda complete neurological status should enable one to arrive at a satis-factory diagnosis. The chief diagnostic problem is syphilitic meningo-myelitis. Bony disease is usually excluded by the x-rays. Multiplesclerosis is not infrequently ushered in with sensory signs, also syringo-myelia. They present real difficulties in diagnosis. The applicationof proper neurological and psychoanalytic procedures will exclude theconversion symptoms of hysteria. Intramedullary or ex
