4i 8 Mr. Hunter’s Obfervations on the 
the arytenoid cartilage, as well as between them, ending below 
the thyroid, which is folliculated on its inner furface on the 
fore part of the cricoid cartilage. 
The epiglottis makes a third part of the paflage, and compleats 
the glottis by forming it into a canal, in feveral of this tribe ; 
but in the Piked Whale it was not attached to the two arytenoid 
cartilages, but only in contadt, or inclofing them at their bafe, 
fo as to make them form a complete canal. 
I could not obferve any thing like a thyroid gland. 
From the glottis and epiglottis being fo connected as to make 
but one canal, and from the thyroid and cricoid cartilages 
being fo flattened in fome between the anterior and pofterior 
furface, the paflage through thefe parts is very fmall or con- 
tracted ; but the trachea fwells out again into a very confidera- 
ble flze. Its larger branches are in proportion to the trunk:, 
and enter the lungs at the upper end along with the blood- 
veflels. 
Of the Lungs. 
The lungs are two oblong bodies, one on each fide of the 
cheft, and are not divided into fmaller lobes, as in the human 
fubjedt. They are of confiderable length, but not fo deep 
between the fore and back part, as in the quadruped, from the 
heart being broad, flat, and of itfelf filling up the fore part of 
tne cheft. They pafs further down on the back part than in the 
quadruped, by which their fize is increafed, and rife higher up 
in the cheft than the entrance of the veflels, coming to a point' 
at the upper end. From the entrance of the veflels they are 
connedted downwards, along their whole inner edge, by a ftrong 
attachment (in which there are in fome lymphatic glands)' to
