TESTS WITH OX KIDNEY AND HOG KIDNEY. 
The results of the feeding experiments with ox kidney and hog 
kidney are presented in Table 18. Fifteen per cent of ox kidney in 
a ration was sufficient to protect three pigeons against polyneuritis 
for a period of 63 days, and all the birds were in good condition at 
the close of the test. The average change in weight of the birds on 
this ration was a loss of 4 per cent. The ration containing 25 per 
cent of ox kidney also protected three pigeons against polyneuritis 
during a period of 63 days and the birds were in good condition at 
the close of the test. The average change in weight of the birds was 
a gain of 6.3 per cent. A fourth pigeon in the pen died on the fifty- 
_ first day from an unknown cause. It apparently was in normal 
condition on the previous day.
