MAMMALIA; 
BY 
JOHN RICHARDSON, M.D., F.R.S., &c. 
The opportunities which a voyage of discovery offers to the naturalist, of 
becoming acquainted with the animals of the countries that are visited, are 
necessarily very limited ; the stay in port is generally short, communication 
with the shore often inconvenient, and frequently dangerous to small parties ; 
and as the crew and officers can seldom be spared from the necessary business 
of the vessel, excursions in-land are rarely attempted. Under such circum- 
stances, the large collection of objects of Natural History made on the present 
voyage are highly creditable to the Commanding Officer, Mr. Lay the 
Naturalist, and other members of the expedition. Mr. Collie, the Surgeon, 
is particularly deserving of commendation for the great attention he paid to 
Zoology during the voyage, evinced by his copious and interesting notes on 
the anatomy of the various animals he dissected,* and an ample collection 
* The limits of this work admit of our giving a few extracts merely from the notes of his dissec- 
tions, which he has recorded at considerable length.
