SECTioif IV.— THE FAT— IN CEETAIN SEPAEATED PAETS, AND IN THE ENTIEE 
BODIES, OF 10 ANIMALS ANALYSED. 
When speaking on the subject of method, it was explained, that a large portion of 
the Fat of the animals analysed, was obtained from their different parts by melting and 
expression, the remainder being determined by extraction with ether. In the melting 
and expression manipulations, the parts were generally classed as under : — 
{a) Kidneys, with the fat surrounding them: 
{h) Other carcass parts, including bones : 
(c) Head, and miscellaneous offal parts : 
(d) Heart with its accompanying fat : 
(e) Caul or omentum fat : 
(f) Mesenteric or intestinal fat. 
The determinations of Fat by ether were made upon the dry residues after the melt- 
ing and expression, which, for the purpose, were mixed or classified to represent — 
{a) Total carcass parts, including bone : 
[h) Head, and other ofial parts, including bone : 
{c) Hair or wool. 
Separate Fat determinations, by ether, were also made upon a mixture representing the 
whole carcass and offal parts together, excluding only hair or wool, and of course the 
previously melted and expressed fat. The actual results of the melting and expression 
experiments wiU be found in Tables I. to X. inclusive, in the Appendix. The ether 
determinations are given in Table XIH. of the Appendix. From the data thus pro- 
vided, have been calculated the percentages of melted and expressed, of ether-extracted,^ 
or of total Fat (and its distribution), in the Carcass, in the Offal, and in the Entire 
Fasted Live-weight, of the several animals. These particulars are given in a some- 
what detailed form in Table HI., and in a more summary one in Table IV., which now 
follow.
