^12 Mr. Hunter’s Obfervatlom on the 
what (lightly covers the veifels in particular parts. It is attached 
forwards, all along to the lower part of the different bags confti- 
tuting the Ifomach, and on the right to the root of the mefen- 
terv, between the ifomach and tranfverle arch of the colon, firff 
behind to the tranfverfe arch of the colon and root, of the me- 
fentery, then to the pofterior furface of the left or firif bag of 
the ifomach, behind the anterior attachment. In fome of this 
tribe there is the ufual paflage behind the veifels going to the 
liver, common to all quadrupeds I am acquainted with ; but in. 
others, as the fmail Bottle- nofe, there is no fuch paifage, 
which by the cavity behind the ifomach in the epiploon of this 
animal becomes a circumfcribed cavity. 
The fpleen is involved in the epiploon, and is very fmail for 
the iize of the animal. There are in fome, as the Porpoife, 
one or two fmail ones, about the iize of a nutmeg, often fmal- 
ler, placed in the epiploon behind the other. Thefe are fome- 
times met with likewife in the human body. 
The kidnies in the whole of this tribe of animals are con~ 
glomerated, being made up of fmaller parts, which are only 
connected by cellular membrane, blood- veifels, and duffs, or 
infundibula; but not partially connected by continuity of fub- 
ftance, as in the human body, the Ox, &c. : every portion is of 
a conical figure, who'fe apex is placed towards the center of 
the kidney, the bafe making the external furface; and each is 
compofed of a cortical and tubular fubftance, the tubular ter- 
minating in the apex, which apex makes the mamilla. Each 
mamilla has an infundibulum, which is long, and at its be- 
ginning wide, embracing the bafe of the mamilla, and becom- 
ing fmaller. Thefe infundibula unite at lad, and form the 
ureter. The whole kidney is an oblong flat body, broader 
mid thicker at the upper end than the lower, and has the 
appearance
