of possible tuberculous infection than a contrast series: and that it approaches that of a group of patients suffering from pulmonary tuberculosis. Bass and Vader (1957), in Eindhoven, collected a series of 128 patients with sarcoidosis, the diagnosis being made on clinical grounds mainly, biopsy evidence being positive in 16. Contact with active tuberculosis, often with longer intervals than two years, within and without the family totalled 23 (18%), to which they added contact with inactive tuberculosis in 17 (13%X,) and with cattle in 6 (5%), giving them a total of 36% with tuberculous contacts; both latter groups were inaccessible in our patient questionary retrospective survey. It seems that their higher incidence may be partly due to different means of selection of the patients, different definition of contact history, and the advantages of a full radiological survey of the possible contacts.
