will be seen further on, how good an index is the percentage of mineral matter, to the 
amount of the fixed nitrogenous compounds of the total body, or its parts. 
In the third main Division of Table II., the amounts of ash yielded by the same col- 
lective parts of the Carcass and of the Offal, are calculated to 100 of the entire anwial 
(fasted Uve-weight), instead of to 100 of the Carcass, or of the Offal 
[“ arrangement if the results we leai-n, that, on the average, the ash Pelded 
total soft parts of the body, amounted to considerably less than 1 per cent, of its entu 
or live-weight. That yielded by the bones, on the other hand, amounted alwy s to niore 
than 1, generally to more than 2, and in some cases to from 3 to 4 per cent, o t e w o e 
body Thus, the bones of the Pigs yielded ash amountmg to 2 per cent, and undei, o 
the weight of the animal ; those of the Sheep to from 2 to 2i per cent. ; and those ol 
the Calf and Bullocks to, from 3 to nearly 4 per cent., of the Uie-weig t. 
It is worthy of remark, that in the fat Pig the ash due to the soft or more edible per- 
tions of the Carcass, amounted to only 0-211 per cent, of the f 
the ash from the soft Carcass parts, of the three fatter Sheep to tom 0 20o to 0 oo9 of 
the live-weight ; and that from the same parts in the fat Bullock to onlv 0 40 pel . 
If its whole^eight. Again, the per cent, in the entire animal o ash ^le to bones, is 
3-35 per cent, in the fat Bullock, against 3-94 per cent, in the half-fat . - 
among the Sheep, in like manner (if we exclude the half-fat one), a diminution m the 
n alilal in the amount of ash from bones, from 2-10 per cent, hi the store animal 
to 1-916 per cent, in the very fat one. In the Pig, the proportion iii the entire anima 
of bony structure, as indicated by the amount of ash of ^ p' „ 
more mai-kedly as the animal fattens. Thus, the ash of the total bones of the stoic I n 
amounted to 2-021 per cent, of the entire amnial, and that from the total bones o le 
Piff to only 1‘298 per cent, of its live-weight. 
Turing now to the last division, or ‘^Filial Sumniaiy,” of Table II., the decline m 
the percentage of minei-al matter in the citire animal, as it fattens, 
brought to view. This decline is indicated not only m the amount oi ^ 
all parts of the body collectively, but in that from both total Carcass, and total Offal i . 
takL separately. The exception is the case of the Offal parts of the fattest Sheep, b 
the large amount of ash in this instance was due to the great quantity of 
matter not removed by washing from the wool. Calling attention to the ‘«;tual hgui s 
“ sTme of the other Lses, it is seen, that, whilst the 
all parts 4-664 per cent, of mineral matter or ash, the fattei BuUock ga - 
Sr cent Again, the whole body of the store Sheep yielded 3164 per cent ot ash. 
Ld that of the fat Sheep only 2-811 per cent. And lastly, whilst the whole of the s^e 
Pig gave 2-669 per cent, of mineral matter or ash, that of the fat one gave on ) 
’"^tS'the results as to mineral matter as a whole, it would appear, that during the 
fattening process, neither the accumulation of minerad matter in the 
that in the soft parts, takes place commensurately with the inciease ol s
