Of our 12 cases, 2 have died, 1 after an intercurrent attackof measles and 1 apparently from exhaustion as a result of thedisease. Autopsies revealed only a general adenopathy. Theglands were of moderate size except those of the retroperitonealregion. In this area the lymphatic glands were very large, vary-ing in size up to the mass of a pigeons egg. Unfortunately, in.

The etiology of this condition is still in question. Brown,of Toronto, thinks it the result of an infection which entersprimarily through the nose and throat. Others have considered 442 LANGLEY PORTER it the result of a chronic intoxication following gastro-intestinaldisturbances.
