V. THIRD EXPERIMENT : DURATION, 52 DAYS 



A female dog, which weighed 9.34 kilos on July 17, was used 

 in this experiment. It was fed daily, until Sept. 7, on the foUowing 

 diet: Mea*:, 94 grams; aluminized biscuit, 143 grams; lard, 30 

 grams ; bone ash, 10 grams ; water, 350 c.c. On Sept. 7, when it was 

 killed, the dog weighed 10.5 kilos. 



The dog was bled to death from both femoral arteries simul- 

 taneously under local Cocain anesthesia. About 620 grams of blood 

 were drawn off. It was noticed that the dog had an irregulär heart 

 beat, that the arteries were very flabby and that the blood clotted 

 very rapidly. The organs were removed in the usual order and 

 with the customary precautions. The Peritoneum showed many ad- 

 hesions. The kidney on the left side was normal in position but 

 larger in size than the kidney on the right side. The right kidney 

 was smaller than normal, calcareous in part and placed horizontally 

 under the diaphragm, with the pelvis pointing down. Where the 

 kidney should have been on the right side, there was a small cyst 

 containing black fluid. The genitals showed no anomalies. The 

 pancreas was very small. 



The bile and gall bladder were tied off as usual, but some bile 

 escaped and contaminated a portion of liver which was quickly cut 

 off. This portion weighed 53 grams and was not analyzed. The 

 rest of the liver was altogether free from the bile which had escaped 

 from the bladder. The analytic results are presented in Table 3.
