the elevation, swelling and filling np of that portion of the skin 

 which contains the sebaceons or suet-like matter. 



Treatment. Open the part with a knife, and inject for a few 

 times into the inside of the tumor a teaspoonful of the tincture of 

 iodide, to kill the walls of the cyst. The surgeon sometimes cuts 

 these tumors out in the form of a soft ball without opening them. 

 This requires a steady hand. 



(2.) Encephaloid. — This term means a brain-like tumor, so 

 named from its structure being like that of the brain. It is one 

 of the kinds of cancers which sometimes attack the horse, but is 

 more frequently seen in the dog and ox. 



Cause. A specific poison in the blood, not as yet well under- 

 stood. 



Symptoms. It is solid, hard, irregular in shape, and knotty, with 

 no hair upon its surface, and presenting a smooth and shining 

 aspect. These tumors grow rapidly, and finally break on the top, 

 presenting an angry and malignant sore or ulcer, which cannot be 

 healed without first removing the entire tumor with a knife, and 

 treating it as for a simple sore.

 to most persons, and is attached chiefly to the skin only. 

 It is troublesome only in so far as it is apt to bleed, thereby

 because of the sweat and flies. 



Treatment. Those persons who have not sufficient nerve to cut 

 them off" with the knife can take arsenic, one drachm ; hog's lard, 

 four drachms; mix, and make an ointment; rubbing in and 

 around the tumor, once a week, a small portion of the salve. In 

 a short time it will fall off". 



(4.) Fatty Tumor. — This is a variety of tumor of frequent 

 occurrence in horses, and is composed of fat, as its name indicates. 

 It is sometimes called adipose and lipoma by the surgeons of 

 continental Europe. 



Symptoms. A round, ovoid shape, with a firm feel, but not 

 hard nor elastic, or at least not so much so as the encysted form. 



Treatment. Take a sharp knife, and after getting a twitch upon 

 the horse's nose, and one of the fore legs held up, make a straight 

 cut ovei the centre of the tumor through the skin onl3\ Then
