tically no difference in the average loss in weight of the two pens of 
birds. By referring to Table 1 it will be noted that the average 
survival period of the birds in pens 2 and 3, which were fed auto- 
claved rice alone, was 20.5 days, or practically the same as that of 
e 
pens 4 and 5 on the ox-muscle rations.

Pen 6 was fed a ration containing 25 per cent of muscle taken from 
the shoulder of another fat carcass of beef. The slightly longer sur- 
vival period and smaller loss in weight indicate a somewhat higher 
ee value for this sample of muscle than for that fed to pens 
4 and 5. 
Pen 7 was fed a ration which contained 25 per cent of muscle taken 
from the loin of another fat-carcass of beef. The survival period of 
this pen of birds was slightly longer than that of pen 6 getting 25 per 
cent of muscle from the round, but this difference is due to the sur- 
vival of pigeon 14 in pen 7 at the end of the test, although it was in 
very poor condition at that time. The three other birds in this pen 
developed polyneuritis on the twentieth, twenty-third, and twenty- 
{th days. In reality, there was probably no material difference in
