Mr. ALDERSON on a Whale of the Spermaceti Tribe. 263 
In the sinus, behind the valves, the thickness was _ not 
greater than that of the pulmonary artery. 
Length of the heart, from the apex to the valves of the 
aorta, 3 feet 10 inches. 
The columne carne were very large, and one of the corde 
tendinez in the tricuspid valve, measured 7 inches in length. 
Near the middle of the left ventricle, the wall of the ven- 
tricle measured about 3 inches. 
The diameter of the coronary artery was 12 inches. 
On the left ventricle being laid open, its capacity was 
guessed, by some farming gentlemen present, to contain from 
8 to 10 gallons. The heart was destitute of fat. 
Larynx and CEsophagus.—These parts, of great interest in 
this tribe, were supposed to have been sent perfect with the 
heart, but, on examination, it was ascertained that the ceso- 
phagus was wholly missing; and, in consequence, the parts 
could not be satisfactorily examined. 
There remained only a part of the trachea, with the cricoid 
and thyroid cartilages as in man, nearly, together with what 
has been termed the pyramid, the connexion of the trachea 
with the breathing tube. 
The urinary and genital organs were not examined; they 
were removed, with other parts of the animal, during the time 
I was occupied in the examination of the head. 
The Stomach.—This organ was cut open by the labourers, 
not with a view to the examination of its structure, but in 
search of ambergris, of which none was found. 
Near the termination of the csophagus was found about 
a bucket-full of the beaks of one of the cuttle fishes. See 
Plate XIV. Fig. 4. 
The lungs and liver were but cursorily examined; indeed, 
the viscera were so quickly removed, with a view to clearing
