TESTS WITH LAMB LIVER AND HOG LIVER. 
In Table 15 are presented the results of the feeding tests with 
lamb liver and hog liver. The ration containing 15 per cent of 
lamb liver had a very low antineuritic value, the average survival 
period of the pen of birds being only 21 days and the loss in weight 
11.4 per cent. The ration which contained 25 per cent of lamb 
liver had a considerably higher antineuritic value, the survival period 
for the pen being 62 days out of a possible 70 days. One pigeon 
developed polyneuritis on the thirty-eighth day, one died from an 
injury on the sixty-eighth day, and the three other birds completed the 
test.. 
The results of the tests with hog liver were more favorable than 
those with lamb liver. The pen of pigeons getting 15 per cent of 
hog liver in their feed showed a survival period of 62 days out of 
a possible 70. One bird developed polyneuritis on the thirty-seventh
