OF THE LARYNX OF THE DOG, HOG, &C. 429 
and throat are comparatively larger and thicker; it is, however, far 
from being so strong and so stout as in the horse, for it has not 
so much occasional pressure to resist, and it is not exposed to so 
much danger. The os hyoides scarcely reaches to the thyroid 
cartilage, and the cornua to which it is united are found on the 
very anterior and upper portion of the cartilage, in order to give 
freer motion to the tongue, and to render it in a manner inde¬ 
pendent of the larynx. The little triangular-shaped body of the 
bone, with an evident capsular ligament attaching the sides to the 
head of it, embraces only the hyo-thyroid ligament. The 
appendices or cornua of the thyroid cartilage connecting it with 
the cricoid are much longer. The epiglottis is shorter and 
rounder than in the horse; the sharp termination of it is rounded 
off; the aperture into the larynx is not so large, and the 
lengthened epiglottis of the horse is not required. Nature seldom 
gives more than the animal requires. We may possibly derive a 
little lesson in the science of gastronomy from this. Report 
speaks very falsely, or many of the tongues that are pickled 
by the drysalter, and find their way to the tables of the tavern 
and elsewhere, never came from the mouth of the ox. The 
epiglottis is generally preserved in the pickled tongue, and will 
always tell tales. This cartilage in the horse has a sharpened 
termination—in the ox it is rounded. The tongue of the horse is 
tied down by the spur of the hyoid bone, and is short and thick. 
The tongue of the ox is released from this curb, and is used 
to clean the whole of the muzzle, and can be insinuated even into 
the nostril. A short plump tongue, then, until the epiglottis 
is seen, is rather a suspicious affair. A long ugly looking tongue, 
with a rounded epiglottis, may be eaten without fear. 
The Dog .—The only difference in the structure of the car¬ 
tilages of the larynx in the dog is, that they are exceedingly 
flexible; they had need be so, considering the extensive and 
rapid and violent motion of the head of the dog, and the pressure 
to which the larynx must occasionally be exposed. 
The Hog .—In the hog I will beg you to observe the little 
space between the arytenoid cartilages. This animal is not one of 
speed : also the development of the epiglottis—comparatively 
much larger than in the larynx of any of our patients. It is not 
only larger, but it is differently constructed. The cellular liga¬ 
mentous substance at its base is far looser than in any of the rest, 
and the epiglottis is more moveable; and not only so, but from 
its increased size, and the curved direction of its edges, when 
it closes upon the aperture beneath, it not only perfectly covers 
it, but in a manner embraces the arytenoid cartilages. This 
formation of the cartilage best suits an animal who is plunging
