examining the same organs in a larger creature, that their use 
was fully developed. The foot of the walrus required diminish- 
ing four times to exhibit it in a quarto plate, whereas that of the 
fly required magnifying 100 times to render it distinctly visible. 
— The second fact relates to the internal formation of the same 
animal. A reservoir of a cylindrical form, the coats of which 
are covered with a thick mucus, receives the bile by a lateral 
communication, and it then propels it into the duodenum. 
From the width of the oesophagus large masses of food can be 
swallowed ; the animal possesses the power of regurgitation ; the 
opening of the pylorus is comparatively small, and is valvular, 
by which the contents of the stomach are prevented from pass- 
ing into the duodenum. These parts, and many of the external 
organs, are of a similar structure to that of the seal. Mr Forster 
states the food of the walrus to be the Fucus digitatus , which is 
found on the Arctic shores, and also under the ice. — The third 
subject of remark was the funis and placenta of the seal. The 
vessels of which the funis is composed, are about nine inches 
long, and are not twisted ; and they anastomose at about three 
inches distance from the placenta, which is connected with them 
by three membranous coats : this conformation admits of great 
freedom in the fetal circulation. 
19. Notice in regard to a Fossil Whale discovered in Dun- 
more Park . — Mr Blackadder, in a memoir lately read before 
the Wernerian Society, announced the discovery in Dunmore 
Park, in Stirlingshire, of the remains of a whale imbedded 
in alluvial soil. The Earl of Dunmore, in whose grounds it 
occurs, in a letter to us on this subject, says, 44 I find that its 
whole remains lie from about half a mile to three quarters of a 
mile from the present bed of the river. It is covered by three 
or four feet of alluvial soil, and is rather more than 20 feet 
above the ordinary spring-tides. Its position above the level of 
the tide-water is about the same as that of the whale found at 
Airthrie. Its length is about 70 or 75 feet. At present it sup- 
ports a good crop of wheat ; but after that is removed, it shall 
be carefully disinterred for the College Museum.' 
20. Habits of the Whale .' — In October last, a whale appeared 
in the river St Lawrence, as high up as the city of Montreal. 
The animal was pursued by numbers of boats, and was at last
