A Description of the internal Parts. 
The panniculus carnosus, which lies immediately under the 
skin, is very strong, and extends over the greatest part of the 
body. 
The tongue is four inches long, and rounded at the end, in 
which there is a slight fissure, giving the tip a bifid appear- 
ance. The papillae on its surface are soft ; they are long to- 
wards the root, but less so near the tip. 
The os hyoides, thyroid, and cricoid cartilages are small 
for the size of the animal, and weak in their texture. The 
cricoid cartilage is not a circular ring, but made up of two 
equal parts, united anteriorly ; their lower edge at this union 
forms an acute angle, the two sides pass a little down upon 
the trachea as they go round it ; and the lower edge laps 
over the upper annular ring of the trachea. 
The thyroid gland is small, and divided into two parts. 
The epiglottis is short, and its edges are attached by means 
of a ligament to the inner side of the thyroid cartilage. The 
passage of the glottis is small. 
The rings of the trachea are circular, and disunited behind, 
so that their edges meet, and when pressed upon, they lap over 
each other, being bevelled off for that purpose. Towards the 
bifurcation of the trachea, the space behind, which is not occu- 
pied by the cartilaginous ring, is much increased. This space 
is occupied by a muscle whose principal fibres are transverse. 
The trachea is very elastic in a longitudinal direction : seven 
inches of its length being readily elongated to 10^, and imme- 
diately upon being left to itself it contracts to its former state. 
The lungs onthe right side have three lobes, two large and
