(7.) Bony Tumors. — A species of tumor attacking the bone, and 

 is called osteosarcoma (which see). When attacking the head, it is 

 called osteoporosis (which see). 



(8.) Varicose. — The horse is not often the subject of varicose 

 tumor of the veins, simply from the fact that no garters or other 

 ligatures are tied around the legs, interfering with a free circulation. 

 The saphena major, however, is the only vein liable to varicose, 

 arising from bulging of the hock -joint, and in cases of bog and 

 blood spavin, and thorough-pin (which see). 



Tympanitis. — This term means drum-belly, such as occurs in 

 cases of flatulent colic (which see). 



Typhia. — Typhinia. — Typhus. — These are continued fevers, 

 and are lit up and fed by a specific zymotic matter in the system 

 which is generated when horses are badly fed and crowded together 

 in an inadequate supply of air. The fevers of glanders, farcy and 

 pyemia are good examples. The seeds of the disease can only be 

 got rid by the efiectual destruction of the typhinia — its existing 

 ferment or leaven. — (See Glanders.) 



Typhoid. — A low form of disease, accompanied with fever. 

 Example : Influenza, or catarrhal fever. (See Influenza, and

 clearly defined, and consequent upon changes that have taken 

 place in the blood of horses — a blood disease resulting in nervous 

 prostration. It is comparatively a new disease, and is, in difi'erent 

 parts of the country, called and known by various names, 

 according to the chief symptom there observed. It is known in 

 New York as cerebro spinal-meningitis by those who have seen the 

 disease, because it is thought to be like when a man is affected in 

 the meninges — or membranes which envelop the brain and the 

 spinal marrow — producing choking, distemper, putrid fever, paralysis 

 ejf the par-vagum, or pneumogastric nerve, on account of the chief
