Inhalation of mercaptan causes rapid and overwhelming results. 

 Anesthesia is complete in less than a minute and, if the animal is 

 not promptly exposed to the air, death follows quickly from re- 

 spiratory depression. 



The administration of the drug per os causes nausea, vomiting 

 and increased peristalsis. There is irritation and impairment of 

 the kidneys, and these organs are rendered more permeable to the 

 passage of glucose. This damage, as shown by the urinary find- 

 ings, rapidly passes off and the kidneys return to normal. 



176. Efforts to precipitate pepsin and erepsin with safranin. 

 M. K. Thornton. Neither pepsin nor erepsin (unlike trypsin) 

 was precipitated by safranin from gastric and intestinal extracts; 

 er, if they were precipitated under the conditions of the tests, the 

 products were inactive. The experiments are in progress.
