it burrows in the banks of streams, and is a good swimmer. The 
Sloths of South America, peculiarly organized for a forest life; living 
entirely among trees, and crawling aiong the under side of the branches. 
Cases 17-30 contain the Deer, Musks, and Horses. In the Deer 
the horns, which, except in the Reindeer, are confined to the males, 
are solid and annually shed and reproduced. The Stag and Fallow 
Deer of Europe, the large Wapiti of North America, the Reindeer 
and Elk of Northern Europe and America, the Rusa and spotted Axis 
of India, and the Brazilian Coassus. The Musks, with their peculiar 
fur and musk bag, are hornless, and have large canine teeth. 
The Horse tribe with solid hoofs, such as the Quagga, and the finely- 
banded Zebras of South Africa ; the wild Asses of Asia. 
3. MAMMALIA SALOON. 
In the Wall Cases of this Saloon are arranged the specimens of 
Four-handed, Rapacious, Glirine, and Pouched Beasts, and over the 
Cases are the different kinds of Seals, Manatees, and Porpoises ; and 
arranged in Table Cases are the general collections of Corals. 
In the central eastern division of this Saloon, suspended from the 
roof, is the skeleton of a Whale from New Zealand (Balana australis), 
a species as important to commerce as the Right Whale of the Nor- 
thern Hemisphere ; it is a young individual, not quite half grown. 
Further, a skeleton of the Bottle-nosed Dolphin (Delphinus tursio), 
of which a large shoal was taken near Holyhead in 1836 ; of the 
Narwhal (Monodo?i monoceros), one of the most singular animals of 
the whale-tribe, distinguished by a long spirally-twisted tusk, which 
projects from the snout in the line of the animal's body. This tusk is 
developed on one side of the snout only (the left), very rarely on both 
sides. In the adult male it reaches a length of six or eight feet, but 
is seldom developed in the female ; hence it is probable, that its use is 
the same as that of the antlers in the stag. The ivory of the tusk 
commands a high price in the market, and was still more valued in 
former times, when it was believed to be the horn of the Unicorn. The 
Narwhal is an inhabitant of the Arctic Seas, and rarely strays to more 
temperate regions. 
Cases 1-20. The Primates or Four-handed Beasts, exclusively native* 
of the warmer parts of the globe, and particularly organized for a life 
among trees. They are often called Quadrumana, from their four 
extremities having, in most cases, a thumb opposed to the other 
toes, so that they are able to lay hold, as it were, with four hands. 
Cases 1-13\ The Monkeys of the Old World are chiefly distin- 
guished by the very narrow division between their nostrils. The 
Gorilla, Chimpanzee, and Orangs have been mentioned above. The 
Gibbons are distinguished by their long fore-arms. The Bern- 
nopitheci, Cercopitheci, and Colobi of the Old World are Monkeys 
with long tails; one of the most remarkable is the Proboscis Monkey 
of Borneo, with its singular long nose ; here also may be noticed the 
Entellus, or Sacred Monkey of the Hindoos, which is religiously
