VITAMIN B IN EDIBLE TISSUES OF OX, SHEEP, AND HOG. 37 
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 which 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.
