Hitherto, we have endeavoured to illustrate, by means of a large amount of labo- 
riously accumulated experimental data, the actual and comparatiye gross comppsmon oi 
certail collective portions, and of the entile bodies, of animals of different descnptions. 
aldt different stages of growth and fatness. By the aid of the information so denved. 
we have sought to estimate the probable composition of the Increase of the amm^ 
whUst fattening, and to show the relation of certain important constituents of the 
increase to those in the food consumed. The results arrived at, imder these heads, 
comprise the most important which the inquiry can furnish, so far as its apphcation to 
Agriculture and Dietetics is concerned. It seems desmable, howeier, at east to pron e 
soL materials for the study of the question of the feeding of ammals, from a somew a 
more Physiological point of view. The data acquired with this ™w, relate to the actual 
wmMs and the proportion in the entire body, of the individual organs, and cei am 
more arbitrarily separated parts. In the selection of subjects m which to deteimi 
these points, J was sought-both to take a sufficient number, to secure pretty tai, 
average results for the different descriptions of animal-and, as far as possible, o pr 
vide the means of tracing the tendency of the relative development of the different pa s. 
as the animals grew and fattened. 
to all, betwefn 800 and 400 animals-Bullocks, Sheep, and Pigs-have been opmat d 
upon. The plan was, to determine the livelvelghU of the ammals just before bein, 
sLghtered; and as soon as possible afterwards (so as to lessen the error ansmg lom 
evaporation), the weights of their ~cs, of each of tie "J'";;”'',” 
some other separated parts. The results for each of the indmdual ^ ^ 
actual weights, and the calculated percentages in the entire body-aie ^ 
ence in Tables XV. to LXIV. inclusive, in the Appendix. Of these. Tables X . ^ 
Will XIX XX., XXI. and XXII., which now follow, are Summaries; and i. 
them the results will be found in sufficient detail to bring to view the few mam points, 
to which alone, special attention will be directed. , . „ , , 
In Table XVII. are given the mean aetnal weiijhts, and m Table Xi . J 
centayes in the entire body, of the different organs and parts of ^ Calros, “ -- 
and 14 Bullocks. Among these, are included the calf and the 2 bulloc ‘s se ec ^

relating to these animals are not particulai'ly calculated (as those lefeiiing ■ 
will be found to be) to illustrate the comparative chai'acters at different stages o gio • ■ 
and fatness. By the side of the mean, or average results, however, are pyen

“ Fat Bullock,” which were selected for analysis.
