of foreign bodies, such as needles, which have found lodgment in 

 the gland, and certain other conditions. Favresse treated by in- 

 unction a year-old female suffering from a fluctuating swelling of 

 the right parotid. In two days the abscess burst and emitted a great 

 quantity of purulent liquid. A second orifice of discharge appeared 

 lower down. Both assumed a fistulous character, and saliva flowed 

 freely when meat was offered to the animal. Treatment by injec- 

 tions of nitrate of silver and inunction of vesicants produced no 

 improvement. The actual cautery was then employed — three times 

 within eight days — and was likewise barren of result. Finally, 

 when the animal had become greatly weakened it was decided to 

 extirpate the gland. The operation being completed, a simple 

 dressing was applied. Two days later this was removed and to 

 the astonishment of the operator, a threaded needle was found lying 

 in the depths of the wound. The needle had evidently originated 

 the trouble and had been overlooked at the time of the operation. 



A maxillary fistula, supposed to have been caused in some man- 

 ner by the buckle of the animal's collar was treated by Brissot with 

 an injection of carbolic acid. The following day the orifice had 

 become closed by peripheral edema thus arresting the discharge of 

 saliva, and in three days was completely cured. 



Siedamgrotzky saw a fistula in a seventeen-year-old animal 

 opening by two orifices at the lower angle of the jaw and- which 

 it was supposed proceeded from the parotid gland. The animal 

 also suffered from otorrhea. The latter condition responded to 

 treatment but the fistula stubbornly refused to heal. Later the dog 

 died from another trouble, and at the necropsy it was found that a 

 mixed tumor, partly an osteo-chondroma and partly an adenoma of 

 a sweat gland, was filling the tympanic cavity and the outer ear 

 passage. 



INFLAMMATION. 



Specific inflammation of the salivary gland is a rare disease. 

 It is frequently confounded with the rather common inflammation 

 of the submaxillary and retropharyngeal lymphatic glands. Simple 

 inflammation through infection by ordinary pyogenic microorgan- 

 isms may take place as a result o£ external traumatism and the pas- 

 sage and lodgment of foreign bodies. An occasional termination 

 of the disease is cystic transformation.
