When referring to the amounts of crude ash as given in Table II., attention was 
called to the fact that the percentage of mineral matter, like that of the nitrogenous 
substance, decreases as the animals mature. This is more clearly seen in the figures in 
Table IV. relating to the pure ash. Thus, comparing the fat ox with the half-fat ox, 
there is not only a lower percentage of pure ash in the entire animal, but a lower propor¬ 
tion of the whole contributed both by the carcass parts and the offal parts. Comparing, 
again, the store sheep, the fat sheep, and the very fat sheep, there is a considerably 
lower percentage of mineral matter (pure ash) contributed from the carcass parts of 
the fat than of the store sheep, and less still from those of the very fat sheep. There 
is also less from the offal parts of the fat sheep than of the store sheep ; but there is a 
considerable excess in the case of the offal parts of the very fat sheep ; and, in conse¬ 
quence, some excess in the percentage in the entire animal. Lastly, comparing the 
store pig and the fat pig, the latter shows a considerably lower proportion of mineral 
matter from carcass parts, from offal parts, and from all parts. 
Referring to the Appendix-Tables I., II., and III. (pp. 885-87), for any further details, 
the following Table, V., shows the percentage composition of the pure ash (that is, exclud¬ 
ing sand and charcoal), of the classified parts and of the entire bodies of the ten animals 
analysed. The upper division of the Table gives the results for the ash of the carcass 
parts, the middle division for that of the offal parts, and the lower division for the ash 
of the entire bodies of the animals (excluding contents of stomachs and intestines). 
When duplicate analyses have been made the mean results only are here given. At 
the head of each division of the Table are given the percentages of crude ash and of 
pure ash, not as in Table IY. in each case calculated to the weight of the entire body, 
but to the weight of the collective parts to which the division refers.
