182 BRONCHOCELE. 



conversation with a dog that I once possessed for several minutes, and one 

 perfectly intelligible to both. 



Inflammation of the larynx is a frequent and dangerous complaint. It 

 usually commences with, and can scarcely be distinguished from, catarrh, 

 except that it is attended by cough more violent and painful, and the dog 

 expectorates considerably. Acute laryngitis is not so frequent an occur- 

 rence ; but there is much danger attending it. Blood must be abstracted 

 to as great an extent as the pulse will bear, or until it becomes evidently 

 affected. To this must follow digitalis, nitre, tartar emetic, and aloes, 

 and to these must be added a powerful blister. A considerable quantity 

 is effused and organised, the membrane is thickened, perhaps permanently 

 so, and the whole of the submucous cellular tissue becomes oedematous. 



The dog is subject to sudden attacks of angina. It has been imagined, 

 from the appearances that are manifested, that some strange body is arrested 

 in the windpipe or the throat. There is no dread of water or of the usual 

 fluids ; the dog will lap once or twice from that fluid which is placed 

 before him, and turns slowly away from it ; and this circumstance gives 

 rise to what is called dumb madness. The dog barks in a particular 

 manner, or rather howls like a rabid dog : he is out of spirits, has a strange, 

 anxious, altered countenance, and is alternately cold and hot. Frequently 

 added to this is redness of the buccal and nasal membranes. He refuses 

 all solid food, and either will not drink or finds it difficult to swallow any- 

 thing. His mouth is generally open, and contains a spumy matter exhal- 

 ing an offensive smell. His tongue, charged with a great quantity of 

 saliva, protrudes from his mouth, and the submaxillary glands are enlarged. 

 To these appearances are added a yellow tint of the eyes, constipation, and 

 a small quantity of urine, surcharged with a deep yellow colour. At this 

 period the disease has generally reached a considerable degree of virulence. 

 Often the inflammation extends to the back part of the mouth and larynx ; 

 and in this last case the respiration is attended by a hoarse, hissing kind of 

 sound. 



The progress of the disease is rapid, and, in a few days, it reaches its 

 highest degree of intensity. It is always fatal when it is intense ; and, 

 when its influence is widely spread, it is a very dangerous complaint. 



Somewhat rarely the subjects of it recover. After death we find great 

 redness and injection in all the affected nervous surfaces, and indications 

 of abscesses in which suppuration was not fully established. 



BRONCHOCELE OB GOITRE 



in the dog is almost daily forced upon our notice. If a spaniel or pug- 

 puppy is mangy, pot-bellied, ricketty, or deformed, he seldom fails to have 

 some enlargement of the thyroid gland. The spaniel and the pug are 

 most subject to this disease. The jugular vein passes over the thyroid 

 gland ; and, as that substance increases, the vein is sometimes brought into 

 sight, and appears between the gland and the integument, fearfully en- 

 larged, varicose, and almost appearing as if it were bursting. The trachea 

 is pressed upon on either side, and the O3sophagus by the left gland, and 

 there is difficulty of swallowing. The poor animal pants distressingly 

 after the least exertion, and I have known absolute suffocation ensue. In 

 a few cases ulceration has followed, and the sloughing has been dreadful, 

 yet the gland has still preserved its characteristic structure. Although
