OF ANIMALS FED AND SLAUGHTERED AS HUMAN FOOD.

different animals, the chief points of distinction are that, in the case of the pigs there 
is a lower percentage of lime, a higher percentage of potash and soda, and a higher 
percentage of sulphuric acid than in the corresponding ash of the ruminants. There 
is also generally a somewhat higher percentage of phosphoric acid in the entire animal 
ash of the pigs and the oxen than in that of the sheep. 
With these few remarks suggested by a consideration of the percentage composi¬ 
tion of the different ashes, we turn now to the bearing of the results as brought 
to view on applying them to calculate the amount, and as far as practicable the 
distribution, of the several constituents in a given live-weight of the different 
animals. 
Accordingly, there is given in Table VI. (p. 880), not as before the quantity in 100 
of ash, but the quantity in lbs. of each ash constituent, in the actual weight of the 
collective carcass parts, in the actual weight of the collective offal parts, and in 
the actual weight of all parts of each of the ten animals. The results are given in 
more detail in the upper portions of Appendix-Tables IV., V., and VI. (pp. 888-90); 
in IV. for the calf and oxen, in V. for the lamb and sheep, and in VI. for the pigs. 
There will be found, besides the amounts in the carcass parts, and in the offal parts 
respectively, those in the entire animal—first, by addition of the quantities in the 
carcass and offal parts ; secondly, calculated from the direct analysis of the entire 
a/nimal ashes; and thirdly, the mean of the two last quantities. For the composition 
of the entire animal, as given in Table VI. (p. 880), this mean result is adopted. 
Again, in Table VII. (p. 881), is given the quantity of each constituent, not in the 
actual weight of the separated parts, and the entire bodies of the animals, but cal¬ 
culated in each case to 1,000 lbs. fasted live-weight; thus giving a comparative view 
of the composition of a given live-weight of the different animals, so far as the 
mineral or ash constituents are concerned. The particulars are given in detail in the 
lower divisions of the Appendix-Tables IV., V., and VI. 
In the Tables VI. and VII. (pp. 880-SI), as in former ones, the upper division gives 
the results for the carcass parts, the middle division those for the offal parts, and the 
lower division those for all parts collectively. 
Before commenting on these Summary-Tables, we would call attention to the close 
accordance which the Appendix-Tables IV., V., and VI. show in the mineral composi¬ 
tion of the entire bodies, calculated in the one case by the addition of the constituents 
determined separately in the carcass and in the offal parts, and in the other from the 
direct analysis of the ash from all parts. It is to be observed that this accordance is 
satisfactory confirmation not only of the correctness of the ash analyses, but of the 
preparation of the proportional mixtures of the different parts for burning, repre¬ 
senting, respectively, the collective carcass parts, the collective offal parts, and the 
mixture of all parts. The result of the comparison will, we think, be found very 
satisfactory in every case excepting that of the entire animal ash of the very fat 
sheep, to the probable source of error in which reference has already been made (p. 874).
