ANTINEURITIC VITAMIN IN FLESH OF TURKEYS, DUCKS, AND 
GUINEA FOWL 
The results of the feeding tests with the dried flesh of turkeys, ducks, and 
guinea fowl are reported in Table IV. Each kind of flesh was fed only to one 
pen of pigeons, 30 per cent of the flesh being used in each ration. The data 
presented in this table show that the turkey flesh had a rather low antineuritic 
value, approximately the same as that of the frying chickens reported in Table 
II. The average survival period with the turkey flesh was 35 days and the loss 
in weight 23.7 per cent. All the pigeons receiving the ration containing 30 
per cent of turkey flesh developed polyneuritis during the test period of 56 days. 
The guinea-fowl flesh had a somewhat higher antineuritic value than the 
turkey flesh, the average survival period of the pen of pigeons receiving a ration 
containing 30 per cent of the guinea-fowl flesh being 44 days, the maximum sur¬ 
vival period 49 days, and the average loss in weight 22 per cent. 
The duck flesh had the highest antineuritic. value of any of the lots of poultry 
flesh tested. The ration containing 30 per cent of dried duck flesh fully protected 
4 pigeons against polyneuritis during the test period of 56 days. Two pigeons 
lost 6.3 and 10.7 per cent in weight, but the other two gained 3.3 and 9.8 per cent, 
the average change being a loss of 1 per cent.

ANTINEURITIC VITAMIN IN HENS' GIZZARDS AND LIVERS 
In Table V are reported the antineuritic values obtained for the dried gizzards 
and livers from hens. The data presented show that the gizzards had a very 
low antineuritic value, the average survival period of the two pens of birds 
receiving rations containing 15 and 20 per cent of dried gizzards being only 21 
and 22 days, respectively. 
The hens' livers had a fairly high antineuritic value, the average survival 
period of the pen of pigeons receiving the ration containing 15 per cent of dried
