Delayed-type hypersensitivity and the immunology of Hodgkin's disease, with a parallel examination of sarcoidosis.

given with respect to anergy and its implications, based on pres ent immunologie understanding. The sources of patients and the types of tests are tabulated, the small numbers studied hardly warranting the usual custom of expressing findings as percentages. Comparison is made in several areas, by tabulation of sources with parallel information secured in studies on sarcoidosis, another disease exhibiting anergy but lacking the pro gressing anergy of Hodgkin's disease. The parallelisms existing
