In the first experiment we find more nitrogen recovered than 
was fed, the larger loss being in the case of Jem, with an extra 
demand made to supply the growth of her foetus. In the second 
period there was stored up considerable nitrogen by both animals, 
showing that they were receiving more than a maintenance ration. 
AMOUNT OF DUNG AND FERTILIZING MATTER CON- 
TAINED IN THE SAME, VOIDED BY COWS. 
The digestion experiment conducted with the two cows, Jem 
and Meg, gave an opportunity for determining the amount of 
dung, and the composition of the same, voided by these animals 
under orchard-zrass hay, and under orchard-grass hay and corn 
meal feed. The average weights of the cows for each period 
were:
