GREAT NORTHERN DIVER OR LOON. 53 
rank, and dark coloured, I have seen it much relished by many lovers 
of good-living, especially at Boston, where it was not unfrequently 
served almost raw at the table of the house where I boarded. 
A female bird particularly examined by me presented the following 
appearances. From the point of the bill to the end of the tail it mea- 
sured 34 inches ; to the claws 41; the extended wings were 71; the bill 
measured 5 inches along the gape; the breadth of the body was 8 
inches, its depth only four ; the wings were 2 inches shorter than the 
tail; and the weight was 10 lb. 11 oz. avoirdupois. The first primary 
was longest. The trachea, which was even and flattened, being in 
diameter about 3 of an inch by 3 inch, was 16 inches long. The eggs 
werenumerous. The gizzard was moderate, and contained many large 
pebbles. The intestines were 7 feet long, and about the same size as 
a Swan’s quill. Every bone and sinew was strong and tough. The 
tongue resembled in shape and size that of the Ivory-billed Wood- 
pecker. The bones of the wing and leg were almost solid, the cavity 
for the marrow being very small. All the bones of this specimen 
were presented to Mr Yuomas Attis, of the Friend’s Retreat, near 
York. 
My friend Captain James Criark Ross, of the Royal Navy of 
England, once placed at my disposal a specimen of the Loon procured 
in a very high latitude, and which, having closely inspected it, I found 
to differ from the one represented in the plate, only in having the 
point of the bill slightly elevated or recurved, and of a fine yellow 
tint. Dr RicHarpson informed me that, on one of his arduous north- 
ern journeys, he saw a very large and handsomely crested Diver, which, 
although somewhat prematurely, I propose honouring with the name 
of Colymbus Richardsoni.
