bag, and generally near the commencement of the oesophagus. 
This speaks volumes as to the depraved appetite of the patient, 
and the paralysis of the muscles of the pharynx; but the pre¬ 
sent lecture must be confined to a dry detail of facts, without 
reference to any theoretical opinion of the nature of the disease. 
The Tonsils .—Little dependence must be placed on the appear¬ 
ance of the amygdala, or tonsils. They have occasionally assum¬ 
ed double or treble their natural size, and they have evidently 
been highly inflamed. This has oftener been the case in the quiet 
than in the ferocious madness. I examine the tonsils with 
other neighbouring parts, but I place little dependence on the ap¬ 
pearance which they present; although I am very much inclined 
to believe that the insatiable thirst of the rabid dog is intimately 
connected with disease of them, and deficiency of mucus to lubri¬ 
cate the passage to the throat. 
The Epiglottis .—I always look to this organ with much atten¬ 
tion, for its appearance goes far to guide my opinion as to the 
real state of the dog. I regard first its anterior surface—more 
anterior than superior in our patients—I will call it the lingual 
surface^ and then we shall clearly understand each other. The 
minute vessels on this lingual surface are more or less injected 
in almost every case of rabies. Sometimes there may be only a 
few ramifications; at others there is a beautiful net-work of ves¬ 
sels covering the whole of this surface. 
There is a connecting band between the epiglottis and the 
very posterior part of the tongue. Human anatomists speak of 
more than one of these bands. I can recoo^nize but one in the 
dog, and which I term the frgenum, or fiaenulum. On either 
side of it there is a deep depression, which I especially examine; 
and I scarcely recollect a case of rabies in which very consider¬ 
able injection of the vessels was not found at the base of the 
fraenum, and deep in this angle. As to the other appearances of 
the epiglottis, they have reference to the degree of inflammation 
rather than to the existence of this diagnostic symptom, if I 
may be permitted so to call it. 
The vessels increase in size, and multiply around the edge of 
the epiglottis; there is thickening of the submucous tissue— 
there is injection of it on the posterior or inferior—the laryngeal 
surface. These would confirm the opinion which I was before 
inclined to form; but, from habit, my attention is first directed to 
the lingual surface, and particularly to the appearance of the 
angle on either side of the base of the fraenum. 
The Glottis .—Inflammation of the edges of the glottis, and 
particularly tumefaction of the mucous or submucous membrane 
which covers its margin, are not unfrequently seen, and go far
