peatedly mistaken for glanders by " horse doctors." If caries of 

 the bones of the head exist, the swelling of the head will be enor- 

 mous — Big-Head, or Osteoporosis — and not Osteosarcoma^ as it has 

 been called. 



Cause. A disposition in the system to appropriate to the bones 

 more calcareous or earthy matter than is required. 



Treatment If caries be confined to the teeth, have them taken 

 out. When confined to the bones of the head, it is incurable. 

 The animal will die of hunger, as he is unable to use his tongue 

 and jaws, or gather and chew his feed. Happily, it is not a com- 

 mon disease. 



Castration. — This is an operation for the purpose of depriving 

 the horse-colt of his entirety by the removal of the testes. It is a 

 simple and safe operation. Any person having once seen it done, 

 can do it also, if he have the resolution to do so. It has been 

 recently demonstrated that castration can be performed on aged 

 horses with as much safety as on those in colthood. This is attrib- 

 uted to the mode or manner of operation, namely, by an instru- 

 ment called the Ecraseur. 



No clamps, no firing nor twitching, nor any trouble afterward. 

 The instrument is manufactured especially for this purpose, by 

 eurgical instrument makers. 



Cataract. — (See Eye Diseases.) 



Catarrh.— (See Cold.) 



Cautery. — This term is applied to the operation of searing a 

 part with a red-hot iron. Happily, this cruel, and in many in- 

 stances unnecessary operation, is becoming among the things that 

 were. It used to be applied to sprains, ring-bones, and spavins. 

 Since the discovery of the preparations of iodine, and their absorb- 

 ent properties, the iron is little used. 



Cerebro-Spinal Meningitis. — (See Typhosus.) 



Chest Diseases. — The diseases of the chest are many and im-, 

 portant. In it are the heart, lungs, and great blood vessels. The 

 diseases of these organs will be found under Inflammation of the 

 lungs, or Lung Fever, Pleurisy, Coughs, Bronchitis, and Glanders. 



Chest Founder. — (See Founder.) 



Chilblains.— (See Frost-Bites.) 



Chill. — This term means a shiver, as if the horse were cold.
