ally a swelling appeared on the right side of the jaw. She 
was killed at the close of the experiment and it was found 
that a tooth had been broken which probably was painful 
and caused shrinkage in weight. The data therefore can be 
used only toshow how importantit is in experimental work 
with live stock to keep close watch over the animals employ- 
ed, and how a small matter may destroy the value of data 
obtained.

The different weighings clearly show there was a steady 
gain. In the first column the weight ranged from 1025 to 
1065, while in the second the range is from 1055 to 1075, 
and in the third from 1070 to 1082. Taking the first col- 
umn as preliminary and the difference between her average 
weight reported in the second column, with that in the third 
as the gain made, there is a difference of 9 pounds or at the 
rate of .27 of a pound per day. 
The dry matter consumed and nutrients actually digest- 
ed, as determined bya digestion experiment, were as follows:
