salt, as might be expected, causing the largest excretion of urea, not, 
however, necessarily from any greater influence on proteid metabolism, 
but merely as furnishing a certain amount of ammonia to be excreted 
as urea. Finally, our results, with both salts, fail to show that dimi-

hypnotic agents, and in this respect, therefore, our results show noth- 
ing antagonistic to Dr. Bill’s conclusion “that bromide of potassium 
in its legitimate action, is an anesthetic to the nerves of the mucous 
membranes and a depressor of their action. Its hypnotic effects are 
secondary.”
