TO THE ARCTIC REGIONS, 37 
differ in every respect from the rest of the finny race, 
except in form, and the element in which they live : 
they have been indeed very properly named by Dr. 
Shaw, the fish-formed mammalia. The skin on-the 
back and sides was mottled, of a black and white 
marble colour, and that on the under part of the 
body was nearly all white; it was very soft, and was 
formed, as in the black whale, of vertical fibres, some- 
what like a transverse section of a piece of wood. 
Immediately under the skin there was a layer of 
blubber, from three to four inches thick, which en- 
veloped the whole body; this coating was stripped 
off and put into casks, and it is expected when boiled 
to yield from sixty to seventy gallons of oil. The 
muscular part of the body was exceedingly black, 
and so soft as to be torn very easily by the hand. 
The lungs were large and of a light fleshy colour : 
the heart was also of a very considerable size, but its 
parietis was not strong in proportion to its bulk. 
The liver was of a dark brown, or chocolate colour, 
and very oily. The stomach contained nothing but 
a small quantity of a greenish oily liquid; and the 
rest of the alimentary canal, although of consider- 
able size, had nothing in it at this time but a small 
quantity of the same sort of fluid. The kidnies 
were large, and composed of a congeries of small 
round masses like those of an ox. The urinary blad- 
der was not larger than that of the animal just men- 
tioned ; the testes were, however, much larger than 
those of any of our domestic quadrupeds. 
I have now only to observe, that the relative situ- 
ation of all these viscera, was the same as in terres- 
trial animals of the mammalia kind.
