Cape Sabine, all of them white, there being evidently in those 
places of the very tar north no time for assuming a summer coat. 
A few specimens of several kinds of small Rodents, such as 
lemmings, and marmots or ground squirrels, were found. The 
males of the Marmots have cheek-pouches for storing food for 
after use. 
The skins, with the heads intact, of six Musk Oxen (Ovzbos 
moschatus) were brought to the vessel from the inland. An 
examination of their skulls is as follows:—Cavity of brain small; 
very prominent orbital projections, eye sockets full of fat; when 
thawed out, the iris brown, pupil light blue. The skull of a calf 
shewed a different contour from those of the mature animals, the 
occipital opening being larger, and the lower mandibles thicker in 
proportion towards the middle. Dentition:—Incisors, 6 in each 
lower jaw; canines, 1 in each side of lower jaw; molars (including 
pre-molars), 6 in each upper and lower jaw of specimens numbers 
I, 2 3, and 6; 5 in each upper jaw of number 4, with a space for 
a 6th, and 6 in each lower, the back portion of 6th not having 
the usual flatness of a molar, but conical and canine-like, and 
received into the vacant cavity of upper jaw; 4 in each u)yper and 
lower jaw in number 5 (calf), the last pointed not flat, but low, 
apparently a tooth in the forming, each 3rd molar in three parts; 
6th molar in each lower jaw of the other skulls in three parts. 
A small branch of crow-berry (Ampetrum nigrum) was attached 
to one of the skins. 
We were well supplied throughout the winter with the flesh 
of the Reindeer or Barren Ground Caribou (Rangifer graenlandi- 
cus), the carcases being brought to the vessel from the island by 
the Esquimo. The flesh of those deer is excellent, and one 
might eat it every day of the year without tiring of it. The 
Caribou are much infested with the large larve of an Céstrian 
dipteron, which are buried in the flesh. 
In many respects, more is known about the infinitesimal 
protozoans than about the Cetaceans, or mammals of the Whale 
tribe, many of which are the giants of the animal world. As a 
rule, only certain parts of their great bodies are to be seen at one 
time, usually when they rise to respire; and, even then, very often 
at a considerable distance from the observer. For this reason, I
