It is obvious that the correctness of the estimates of the com- 
position of increase recorded in the Tables will entirely depend 
upon the degree of identity of the composition of the specimen 
animals analysed with that of those to which the analytical data 
are applied in the calculations. The results must indeed be 
looked upon as only approximations ; though we believe the 
data now supplied constitute the most reliable basis for estimates 
of this kind at present at command. 
So far as oxen are concerned, we have taken for our estima- 
tions of the composition of increase the best experiments on 
record with which we are acquainted, that show, so far as can 
be judged, a progress comparable with that supposed in the 
change from the condition of the " half-fat " to that of the " fat- 
ox " analysed. 
In regard to sheep and pigs, we take the data supplied by our 
own numerous feeding-experiments, the results of most of which, 
so far as the relation of gross increase in live-weight to the 
amount of food, or its constituents, consumed, is concerned, have 
already been published in full, either in this Journal or elsewhere, 
and of which a condensed summary is given at the commence- 
ment of this Article. 
By the side of the estimates of the composition of the increase 
of the fattening pigs there is given, for the sake of comparison,
