326 DISEASES OP CATTLE. 



This is a tumor consisting chiefly of fat cells. The growth is 

 irregularly rounded and distinctly lobulated, very soft, and almost 

 fluctuating. It is insensitive, grows slowly, and is always inclosed 

 in a distinct fibrous capsule, from which it can be easily shelled out. 

 It may become very large and often hangs pendulous from a long 

 elastic pedicle. In cattle this tumor may be found in the subcu- 

 taneous tissues, especially of the back and shoulders, uterus, and 

 intestines, and in the latter position it may cause strangulation, or 

 " gut tie," by winding around a loop of the intestine. 



Treatment. — When found on the skin the tumor may be readily 

 removed with a knife or by a ligature. Caustics and the cautery 

 produce wounds that heal slowly and can not be recommended in the 

 treatment of this tumor. 



CHONDROMA. 



This tiunor formation is composed of cartilage cells. It is a 

 rounded and very often unevenly nodular and sharply described 

 tumor. It is very hard, dense, elastic, and painless and develops 

 principally where we find normal cartilage cells. It is rare in 

 cattle, but has been found in the subcutaneous tissues and nasal 

 cavities. 



Treatment. — Extirpation. 



OSTEOMA (BONY TUMOB). 



Bones may occasionally grow in such a profuse and irregular 

 manner that the product, or osteophyte, assumes the character of a 

 tumor. The bone tissue may possess either spongy or compact prop- 

 erties and grow either from the periphery of the bone or within its 

 interior. These tumors most frequently appear about the head of 

 the animal, either upon the jawbones, within the nasal passages, or 

 in connection with the horns. They are usually of bony hardness, 

 painless, benign, and sharply outlined. 



Treatment. — The treatment consists in either removing them with 

 a saw, chisel, or trepliine, or preventing their further development 

 by counterirritation with blisters or firing iron. 



Characteristic myxomas are mucoid tumors which chiefly originate 

 from the mucous membrane and are especially to be found within 

 the nasal passages and uterus of cattle. They can reach a size of 

 three fists, are smooth or veh^tlike, or may be lobulated, broad at the 

 base, and consist of a glassy-looking mass of connective tissue, which
