3 SS Mr . Hunter’s Obfervations on the 
In animals of the fame clafs living on land, the fat is more 
diffufed : it is fituated, more efpecialiy when old, in the inter- 
faces of mufcles, even between the fafciculi of mufcular fibres, 
and is attached to many of the vifcera ; but many parts are 
free from fit, unlefs when difeafed, as the penis, fcrotum, 
tefticle, eyelid, liver, lungs, brain, fpleen, &c. 
In fifh its fituation is rather particular, and is mod com- 
monly in two modes ; in the one, diffufed through the whole 
body of the fifh, as in the Salmon, Herring, Pilchard, Sprat, 
&c. ; in the other, it is found in the liver only, as in all of the 
Ray kind, Cod, and in all thofe called White-fifh, there being 
none in any other part of the body *. The fat of fifh appears 
to be diffufed through the fubftance of the parts which contain 
it, but is probably in diftindl cells. In fome of thefe fifh, 
where it is diffufed over the whole body, it is more in fome 
parts than others, as on the belly of the Salmon, where it is in 
larger quantity. 
The fat is differently inclofed in different orders of animals. 
Ill the quadruped, thofe of the Seal kind excepted, in the 
bird, amphibia, and in fome fifh, it is contained in loofe 
cellular membrane, as if in bags, compofed of fmaller ones, 
by which means the larger admit of motion on one another, 
and on their conne&ing parts ; which motion is in a greater or 
lefs degree, as is proper or ufeful. Where motion could anfwer 
no purpofe, as in the bones, it is confined in dill fmaller cells. 
The fat is in a lefs degree in the foies of the feet, palms of the 
hands, and in the bread's of many animals. In this order of ani- 
mals and the Seal kind, as far as I yet know, it is difpofed of in 
two ways ; the fmail quantity found in the cavities of the bodv, 
* The Sturgeon is, however, an exception, having its fat in particular 
fituations, and in the interfiles of parts, as in other animals.
