56 per cent, was recovered in the manure, and that the value of the 
manure toas one-fifth of that of the food. 
We will now pass on to tlie conclusion of tlie experiment.

At the beginnings of the experiment in December, No. 60 
weighed 88 lbs., and, at the last, 130 lbs., an increase of nearly 
42 lbs. 
No. 67 weighed at first 99 lbs., and at last 130 lbs., showing 
an increase of 31 lbs. live-weight. 
If the constitution of these two sheep at the first be calculated 
according to the proportions of the two sheep then slaughtered, 
we shall come to the following ultimate conclusions as to their 
increase.

It results from these figures that No. 60 exhibits an increase of 
41'8 lbs. live-weight, but only of 28 lbs. of useful products, 
whilst No. 67 gave nearly 27 lbs. of useful products to 30'8 live 
increase. These anomalies are probably to be explained by the 
varying amount of the contents of the bowels. 
It being assumed that this account of the increase is correct, 
it becomes easy to calculate the nitrogen assimilated by the 
sheep. 
Some flesh selected from the cutlet gave, on analysis, a mean 
percentage of 3"35 of nitrogen. The wool of No. 60 gave 9 "57 per 
cent. : that of No. 67, 7*94 per cent, (a remarkable difference) ; 
the tallow only "32 per cent. On these data, tliere had been 
assimilated by —
