The excretion of free and conjugated histamine in the urine has been determined after oral administration to mice, rats, rabbits, guinea pigs, and dogs. In mice and rats up to 37 per cent of the administered dose could be recovered largely in the free form. In the other species from 3 to 20 per cent was recovered chiefly as conjugated histamine. Rabbit and pigeon liver slices in vitro were capable of conjugation of histamine. Conjugation was also obtained with a cell free extract prepared from an acetone powder of pigeon liver; with this preparation it was shown that coenzyme A is required for the process.
