liver being 38 days, and the average loss in weight only 4.4 per cent. One bird 
survived the test period of 56 days, having gained 12.5 per cent in weight, while 
the three others lost in weight and developed polyneuritis. 
The ration which contained 20 per cent of dried hens' liver fully protected 
a pen of 3 pigeons against polyneuritis and loss in weight for 56 days. Only 
3 pigeons were used in this pen on account of the limited supply of hens' livers.

ANTINEURITIC VITAMIN IN HENS' EGGS 
In Table VI are reported the antineuritic values obtained for White Leghorn, 
Barred Plymouth Rock, and Rhode Island Red eggs. Each lot of dried eggs 
was fed to 4 pens of 4 pigeons each. The results of these experiments show that 
the eggs from each of the three breeds of chickens had a rather low antineuritic 
value. The average survival periods of the pigeons getting rations containing 
25 and 30 per cent, respectively, of the eggs from each breed of chickens were 
as follows: White Leghorn, 33 days; Barred Plymouth Rock, 31 days, and 
Rhode Island Red, 27 days, while the average losses in weight were 11.5, 8.5, 
and 7.3 per cent, respectively. The rations containing the smaller percentages 
of eggs had about the same antineuritic values as the check rations in Table I, 
while the rations containing as much as 25 or 30 per cent of eggs had slightly 
higher values. Only 2 pigeons out of the 48 that were fed the egg rations sur¬ 
vived the test period of 56 days; one was in fair condition at the close, while the 
other was greatly emaciated. It is to be noted, however, that while the average 
survival period of the pigeons receiving rations containing 30 per cent of dried 
eggs are not high, yet the average losses in weight are relatively low.
