 each ; repeated once or twice a day, as the health would bear 

 them. Extirpation is however the most elig-ible remedy, 

 and may be, in most cases, practised with safety by an expe-

 glandular, from its circumscribed form, no difficulty will be 

 found in detaching the whole morbid substance ; but when it 

 has attacked the muscular, cellular, or superficial parts, as 

 the face, parieties of the abdomen, scrotum, vulvae, or ute- 

 rus, then the utmost caution is requisite to remove every dis- 

 eased portion. It must also be taken into the account, that 

 although, in the canine cancer, ulceration does not often re-

 judiciously performed, yet, when the constitution has long 

 been affected with this ulcerative action, it is very apt to 

 appear in some neighbouring part soon after. This subject 

 will be continued, and dilated on, when treating of Scir- 

 rhous Tumours. 



Canker in the Ear. 



From confinement and luxurious living, dogs become sub- 

 jected to various complaints, that evidently arise from the 

 formation of too great a quantity of blood, and other juices ; 

 which, not being spent in the support of the body, find them- 

 selves other outlets. Canker in the ear is evidently pro- 

 duced by this disposition in the constitution to throw off the 

 superfluity accumulated within. In these cases, the dog is 

 first observed to scratch his ear frequently ; on looking with- 

 in which, a red granular or scabby appearance is seen, from 

 extravasated blood become dry. If the complaint is not 

 stopped in this state, it proceeds to ulceration, when the in- 

 ternal part of the ear, instead of being filled with dry blood 

 as before, will be found always moist with matter. The dog 

 now continually shakes his head from the intolerable itching; 

 and, if the root of the ear is pressed, the matter within
