aspect of the jaw. As a rule, it is first noticed when it has attained 

 the size of a nut or small apple and by the animal exhibiting diffi- 

 culty in the act of prehension. The growth is insensitive and of a 

 pinkish or reddish tint, the size varying according to the stage of 

 development and the breed of dog affected. Its surface is irregular, 

 knotty, or lobulated, and covered with intact mucous membrane. 

 It is generally sessile with broad base and immobile from the sur- 

 rounding textures, but may be pedunculate. Contrasted with other 

 sarcomata its consistence is firm. In most cases but one rapidly- 

 growing tumor is present; at other times several may be seen with 

 confluent base. It may develop to such extent as to cause separation 

 of the lips. The adjoining teeth are hidden or forced out of their 

 sockets by upheaval. 



Treatment. The entire growth should be excised as soon as 

 possible by means of a strong pair of short-bladed scissors or bone 

 forceps and the wound thoroughly cauterized to assist in the elimina- 

 tion of the morbid cells as well as to arrest the attendant hemorrhage. 

 It may be found necessary to remove one or more teeth. It is better 

 to remove too much tissue than too little in dealing with sarcoma. 

 Very large tumors require the use of hammer and chisel, and sub- 

 sequently the curette to effect their removal from the bone. During 

 the operation, which must be done under anesthesia, the muzzle 

 should be depressed to guard against escape of blood into the 

 trachea. 



Rizzieri recorded having treated and completely cured a case 

 in which the growth had invaded the whole of the right face, ex- 

 tending from the inner angle of the orbit to the lips. Cadiot and 

 Almy claimed a definite cure after a second operation in which deep 

 excision, curettage of suspected points, and cauterization were 

 practiced.
