have been adopted, in either subject, at an earlier period ; 

 but, when admitted to my hospital, the disease was too 

 far advanced, and secondary deposits had occurred else- 

 where. 



Gum cancer is somewhat exceptional in the canine race; 

 and, when it occurs, is generally associated with alveolar 

 disease, bad teeth, or necrosis of the jaw. 



BRONCHOCELE. 

 Bronchocele, Thyrocele, or goitre, an enlargement of the 

 thyroid glands on one or both sides, is commonly met with 

 in every breed of dogs. The cause of this glandular en- 

 largement is somewhat doubtful. Animals in a debilitated 

 condition appear most liable to it, while, on the other hand, 

 those in robust health will become affected. 



The anatomical formation of the neck and throat would 

 seem to have some predisposing influence ; for short, thick- 

 necked, throaty dogs are those, according to my experience, 

 most frequently the subject of this disease. 



Symptoms. — Bronchocele may come on insidiously or 

 suddenly ; hence we hear of dogs, to use a common ex- 

 pression, with " kernels " in the throat, which have been 

 observed there for some time, but become no larger. 

 Others are discovered to have an immense swelling at the 

 throat, which was undetectable the previous day. 



In cases where the thyroid enlargement is considerable, 

 difficulty in breathing will be one of the prominent symp- 

 toms : this arises from pressure by these enlarged glands 

 on the trachea, which also cause much inconvenience to 

 the neighbouring structures, as the throat and vessels of 

 the neck, creating obstructed circulation and difficulty in 

 swallowing. 



Treatment. — Our object in the treatment of bronchocele 

 is to arrest growth and promote absorption. Iodine, ex- 

 ternally and internally, is the most powerful remedy tor
