Studies of the incidence of epilepsy in the offspring of persons with epilepsy have hitherto been made almost exclusively with institutionalized patients. Such patients, however, are a highly selected group, for in addition to the presence of seizures there have occurred mental changes, principally deterioration and clouded states, which necessitated hospitalization. The great mass of persons with epilepsy who are not institutionalized have not been included in such studies because writers in institutions have had no contact with them. Some characteristics of extramural patients have already been indicated by one of us (H. A. P.);1 namely, only 6.5 per cent show deterioration, the remainder adjusting themselves to life as well as their fellowmen; they come of a stock with a lighter burden of neuropathy; they have fewer seizures; the onset of the disease is later, and the disease has more and longer remissions.
