3rd chamber is not unlike in its position and relations the 3rd 
compartment in the ISTarwhal. The mode of description employed 
by Max Weber has, however, the merit of greater simplicity. Like 
myself, he recognises the oesophageal and cardiac chambers as 
structurally and functionally distinct compartments ; but he groups 
all the compartments between the cardiac chamber and the duodenum, 
whatever may be their number, under the name of the “ pylorial ” 
division of the stomach. He regards this division as characterised 
in structure by the possession of mucous glands similar to those 
present in the pyloric part of the stomach of the Carnivora.* 
The stomach of the Granton B. rostrata contained about 2 gallons 
of a greenish fluid, in which numerous nematoid worms and broken 
pieces of the bristles of the baleen plates were suspended. Ho 
definite light, therefore, as to the food of this whale was obtained 
from this dissection, but from the scanty references to this subject 
in cetological literature it would appear that the Lesser Korqual lives, 
in part at least, on fish. John Hunter found the bones of fish, and 
in jDarticular he refers to dog-fish, as present in the stomach of his 
specimen. Dr M‘Bain stated that the stomach of the Rorqual found 
near the Bell Rock contained a considerable quantity of pultaceous 
matter, “ with bodies of the vertebrse and bones of the herring 
intermingled throughout the mass.” Messrs Carte and Macalister 
found the crystalline lens of a small fish in the stomach of their 
specimen. Professor Flower says the remains of numerous fish of 
considerable size — his informant thought cod-fish — were got in the 
stomach of a specimen caught at Overstrand, Cromer, on the coast 
of Horfolk, in 1860.f In Mr Perrin’s specimen small pebbles were 
found in the stomach. As the animal is apj)arently a fish-eater, it is 
possible that the nematoid worms found in the stomach of the Granton 
specimen had belonged to the fish on which the animal had fed.J 
* Messrs Sims Woodhead and R. W. Gray have given an account {Jour, 
of Anat. and Phys., Jan. 1890) of the structure of the mucous membrane of 
the stomach of the Narwhal, and have found in intermediate compartment 3 
in the stomach of that animal glands adjoining compartment 2 which have 
the structure of peptic cardiac glands, others adjoining compartment 4 like 
mucous pyloric glands. This compartment is therefore histologically, as well 
as topographically, intermediate.

month of July to have its stomach and intestines filled with the Copepod
