TESTS WITH, OX HEART AND HOG HEART. 
Four pens of pigeons of four birds each were fed rations containing 
15 and 25 per cent of ox heart and of hog heart, respectively, during 
a period of 55 days. There was not a single case of polyneuritis 
and every bird had gained in weight, the percentages ranging from 
2.7 to 21.1. The average gains for the pens of birds ranged from 
6.9 to 14.3 per cent, the ] pigeons getting the ox-heart rations making 
slightly larger gains than the others. The high antineuritic value 
of ox heart and hog heart is evident. Figures 25 and 26 show the 
changes in the weights of the pigeons fed ox heart and hog heart.
