332 ON ABSORPTION FROM 



injection of a lymphagogue previously to the introduction of 

 the colored solution into the peritoneal cavity. 



V. Dog, 20 kilos. Cannula in thoracic duct and in each ureter. 

 Cannula for intravenous injection in facial vein. The flow of 

 urine and lymph being found satisfactory, at 11.33-11.34 50 c.c. 

 of 20 per cent sodium chloride solution were infused intrave- 

 nously. In the succeeding twenty-five minutes 46 c.c. of lymph 

 and 112 c.c. of urine were collected. At 11.44 12 c.c. strong 

 indigo-carmine solution were introduced into the peritoneal 

 cavity. Blue color appeared in the urine at 11.48, and rapidly 

 increased in intensity. At 11.63 the lymph assumed a faint 

 bluish tint, which grew more pronounced, but was never very 

 deep. When the lymph flow diminished again, a solution of 

 5 grams of Grubler's " pepton " was infused intravenously at 

 12.15. The urinary flow ceased at once. The lymph continued 

 blue in color, 26 c.c. being collected in the succeeding fifteen 

 minutes. 



Thus the color first appeared in the urine in four minutes ; in 

 the lymph in nine minutes. 



VI. This experiment has already been referred to briefly. 

 Dog, 15 kilos. Cannula in thoracic duct and in each ureter. 

 A previous injection of heteroalbumose had stopped the urinary 

 flow. The lymph flow in ten minutes was 4 c.c. At 5.0 10 c.c. 

 indigo-carmine solution (in 0.7 per cent sodium chloride solution) 

 were introduced into the peritoneal cavity. At 6.0 the serum 

 obtained from a sample of blood showed a faint bluish tinge. 

 No pigment could be detected in the lymph, which was still 

 flowing steadily. 



VII. Dog, 15.5 kilos. Cannula in thoracic duct and in each 

 ureter. Cannula for intravenous injection in facial vein. After 

 a solution of 8 grams of Grubler's " pepton " had been in- 

 troduced into the latter, the urinary flow practically ceased. 

 The lymph flow in ten minutes was 10.6 c.c. Immediately after 

 the infusion of the albumose-peptone 10 c.c. saturated aqueous 

 indigo-carmine solution were introduced into the peritoneal cav- 

 ity. The lymph continued to flow abundantly; no blue could 

 be detected in it within three hours. A post-mortem examina- 

 tion showed the pigment distributed throughout the abdomen ; 

 the thoracic cavity was entirely free from it.
