TESTS WITH OX LUNGS AND LAMB LUNGS. 



In Table 23 are presented the results of the feeding tests with 

 ox lungs and lamb lungs. The ox lungs appeared to have a fair 

 antineuritic value. Two of the pigeons w r hich were fed the ration 

 containing 15 per cent of ox lungs were in good condition at the 

 close of the test; one bird developed polyneuritis on the forty-second 

 day; and the other died at the same time. The ration containing 

 25 per cent of ox lungs had a somewhat higher antineuritic value. 

 Two of the pigeons were in good condition and two were in fair 

 condition at the close of the test.

Lamb lungs appeared to have a rather lower antineuritic value 

 than the ox lungs tested. The ration containing 15 per cent of lamb 

 lungs protected four pigeons against polyneuritis for an average 

 period of only 33 days, and the ration which contained 25 per cent 

 of the tissue protected four birds for an average period of 51 days. 

 Two birds getting the latter ration died of inanition on the forty-fifth 

 and fiftieth days, respectively, after having suffered severe losses in 

 weight, but without showing any characteristic symptoms of poly- 

 neuritis. The two surviving birds were in poor condition at the 

 close of the test. 



The changes in the weights of the pigeons during the test are shown 

 in Figures 37 and 38.
