Patients who showed 100 per cent absorption of congo red dye from the blood stream at the end of one-half hour after the intravenous injection of 10 cc. were chosen for this study. Most patients presented albuminuria and cylindruria of varying degree, and a significant number had enlarged palpable livers and tuberculous enterocolitis. The presence of an enlarged
