This report represents the results of the first eighteen months of our experience in the clinical use of a bismuth preparation for oral administration (sobisminol mass),1 which has been made available through the cooperation of Professor Hanzlik of Stanford University.2 It was supplied in capsules containing the reaction product of sodium bismuthate 0.2 Gm., triisopropanolamine 0.4 Gm., propylene glycol 0.1 Gm. and ethyl alcohol 0.1 Gm.
