DIGESTIBILITY OF ORCHARD-GRASS HAY AND 
CORN MEAL. 
ORCHARD-GRASS HAY. 
The analysis of the feeds, unconsumed hay and dung, together 
with the other necessary data, having been given, we here, to 
prevent multiplicity of figures to confusion, give only thé general 
average for the trials with the two cows. We may again state 
that, in the first trial, although the cows were fed more hay than 
was consumed, yet for the whole period there was a slight loss of 
nitrogen from the body, more being recovered in the excrements, 
including the milk, than was contained in the hay eaten. In the 
case of Jem the loss of nitrogen was greater than with Meg, due 
undoubtedly to the needs for the foetus.
