ous ; I have removed them from the cheek, back, side, thigh, 

 and axilla. 



They possess a very low organization unless injured, when 

 they will become inflamed — though this is a very rare occur- 

 rence in the dog. 



Their growth is usually slow, and dependent, to a great ex- 

 tent, on the condition of the patient ; in other words, these 

 tumors being composed of adipose tissue, they increase in 

 proportion to the obesity or development of this tissue in 

 other parts of the animal. 



Diagnosis is generally simple. The substance is smooth, 

 movable, unattached, and pressure produces no pain. 



Treatment. — Excision, which in all cases may be safelj' 

 and successfully adopted. One long incision, nearly the 

 length of the substance, is made, the skin reflected back, and 

 there being nothing but areolar tissue to divide, the tumor 

 is easily and quickly removed from its bed. The lips of the 

 incision are then drawn together with silk sutii. , and the 

 part afterwards may be treated as a common wound. 



Fibrous Tumors. — These occasionally come under the 

 notice of the canine surgeon. They usually proceed from in- 

 juries, and are chiefly found in connection with the jaws or 

 limbs. 



Diagnosis.— Th&y have a firm attachment, are irregular in 

 surface, hard, and insensible to pressure. 



Treatment. — Excision is most advisable; but from the 

 tumor frequently being adherent to the integument, it is not 

 so easily accomplished as in the previous kind. 



On examination after removal, the tumor will generally be 

 found to be composed of a cyst (Fibro-cystic),* filled with 



* In the "Veterinary" for January, 1871, Messrs. Gowing & Son re- 

 cord a case of cystic tumor in the lumbar region of an aged spaniel dog, 

 which they removed by excision. " The tumor presented several peculiar 

 features; its walls were principally composed of white fibrous tissue, in- 

 termixed with a few fibres of yellow elastic tissue. Besides the cyst which 

 Mr. Gowing punctured, there was another of equal size which contained 

 about four ounces of fluid, having the appearance of pus slightly tinged
