These symptoms persisted after a second lesion had been placed slightly deeper than the first. The patient died 5 months after the operation from causes which had no evident connection with the neurological disease. It seemed that the history of this case, together with the report of the autopsy findings, might give useful information on the morbid anatomy of hemiballism.

Report of a Case  A 35-year-old white man was admitted in June, 1957, with a past history of operation for cleft palate and of bronchiectasis.The actual illness started in 1946 with slight tremor of the left thumb and involved the whole extremity soon afterwards. The other arm became gradually affected by tremor and rigidity 6 months later. Four years later an attack of "severe flu" increased the severity of the Parkinson
