account for the less size of those seen by Scoresby, whose 

 whaling-experience was almost wholly confined to the former 

 region. The females are larger and fatter than the males. I 

 append the measurements of one of the largest Whales recently 

 killed in Davis Strait, for which we are indebted to Dr. Robert 

 Goodsir.

The length along the curve of the back and other measure- 

 ments desirable to have been taken could not be made out, owing 

 to the position of the Whale, as it was suspended in the water 

 alongside. 



(7) Habits, ^'c. — The Right Whale is a gregarious animal, being 

 generally found in small " schools " of three and four, but when 

 travelling from one part of the ocean to another they will sometimes 

 collect in large parties. I am informed by Dr. James M'Eain 

 R.N., that about thirty years ago he witnessed an extraordinarv 

 migration of this nature a little to the south of Pond's Bay. The 

 Whales to the number of several hundreds passed north in a 

 continuous flock, and a few days afterwards were succeeded by an 

 even still more numerous herd of Walruses. The numbers of the
