THE PERITONEAL CAVITY. 335 



gradually grown less deep, now showing a light green tint. 

 Therefore at 2.45 a further 20 c.c. of the same indigo-carmine 

 solution were infused into the vein. At 2.55 the urine grew 

 deep blue a second time, and at 3.08 the lymph began to show 

 a faint blue tinge which scarcely increased in color. Lymph 

 flow in succeeding forty minutes was 10 c.c. The dog was 

 killed by bleeding and the thoracic duct showed no blue color 

 in any part of its course. 



Thus the color appeared in the urine in ten minutes ; in the 

 lymph in twenty-three minutes. 



IX. Dog, 11 kilos. Cannula in thoracic duct and in each 

 ureter ; cannula for intravenous injection in right facial vein. 

 The dog had been without food or water for two days ; 50 c.c. 

 0.7 per cent sodium chloride solution had been infused slowly 

 into the facial vein. Lymph flow in ten minutes was 3.1 c.c.; 

 urinary flow was 0.9 c.c. At 11.42-11.44 15 c.c. strong indigo- 

 carmine solution were slowly introduced intravenously. At 11.59 

 the urine was colored blue and quickly grew intense in tint. At 

 12.05 the lymph showed a faint bluish tint, which grew slightly 

 deeper ; but at 12.25 the color was doubtful. Therefore 25 c.c. 

 indigo-carmine solution were again injected, whereupon at 12.33 

 the lymph again showed the blue tint, which deepened somewhat 

 to light blue. 



Thus the color appeared in the urine in seventeen minutes ; in 

 the lymph in twenty-three minutes (or with a larger quantity of 

 colored solution in eight minutes). 



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

 ureter; cannula for intravenous infusion in left facial vein. 

 Urine and lymph flow well ; lymph in ten minutes was 3 c.c. 

 At 12.20-12.21 20 c.c. 1 per cent indigo-carmine solution in 

 1 per cent sodium chloride solution were introduced into the 

 vein. At 12.28^ the urine was deep blue ; at 12.32 a trace of 

 blue appeared in the lymph and gradually increased somewhat 

 in depth of color. At 1.0 20 c.c. 20 per cent sodium chloride 

 solution tinged with indigo-carmine were infused. The accelera- 

 tion in the flow of urine and lymph immediately followed. The 

 urine grew less deeply blue ; the color was missed entirely in 

 the lymph. 



Thus the color appeared in the urine in eight minutes ; in the 

 lymph in twelve minutes.
