194 DISEASES OF THE HORSE. 



the fatty tumors, this is called occlusion, and when cleverly 

 done, looks well. 



(5.) Cancerous. — (See Melanosis.) 



(6.) Mellanoid. — (See Melanosis.) 



(7.) Bony Tumors. — A species of tumors attacking 

 the bone, and is called osteosarcoma^ (which see) and 

 when attacking the head, it is called osteoporosis. (Which 

 See.) 



(8.) Yaricose. — The horse is not often the subject of var- 

 icose tumor of the veins, simply from the fact that no 

 garters or other ligatures are tied around the legs, inter- 

 fering with a free circulation. The saphena major how- 

 ever, is the only vein liable to varicose, and arises from 

 bulging of the hock-joint, and in cases of bog, and blood 

 spavin, and thorough pin. (Which see.) 



Tymapanitis. — This term means drumbelly, such as 

 occurs in cases of flatulent colic. (Which see.) 



Typhoid. — A low form of disease, accompanied 

 vvith fever, example. Influenza, or catarrhl fever. (See 

 Influenza, and Gastritis Mucosa.) 



Ulcers. — I do not intend to speak of internal ulcers, 

 as of the brain, chest, or belly, as they are beyond the 

 skill of the most learned, much less the non-professional 

 reader, but will confine myself to external ulcers, as of 

 the skin and flesh. 



(1.) Healthy Ulcers. — These are generally the re- 

 sult of an accident, or incision with a knife, or other in- 

 strument. Every sore which does not heal by what is 

 called the first intention, but suppurates, is called a 

 healthy ulcer.
