My purpose in this paper is to invite attention again to the question of the absorption of various bismuth salts when given intramuscularly in the treatment of syphilis. Cole and his co-workers1 reported their observations on metallic bismuth, bismuth oleate, bismuth and oxybenzoic acid, bismuth salicylate and potassium bismuth tartrate. The roentgenograms made from patients treated with intramuscular (buttocks) injections of bismuth subsalicylate, potassium bismuth tartrate, bismuth sodium tartrate and one unknown salt are here presented.
