 detect this morbid process in the early stage. 



TREATMENT OF OSSIFIED LATERAL CARTILAGES. 



Precisely the same treatment as that indicated for Ringbone 

 will remove both the causes and the effects, and render the 

 animal perfectly sound again. If absolute and complete ossi- 

 fication has ensued, I cannot predicate such a result, but the 

 worst cases can be immensely benefited by expanding the 

 quarters, and giving plenty of room for these hardened tissues. 

 Mercurial applications, too, are beneficial when the animal is 

 not too old. See Appendix of Formula? for the Preparations. 



CORN. 



CAUSES AND SYMPTOMS— THE OLD THEORY. 



I used to believe in a very pretty theory concerning the 

 cause and seat of corn until I knew better. According to that 

 theory, the seat of corn was exactly under the wing of the 

 coffin-bone, and the cause, vertical pressure and concussion 

 produced by the combined weight of the animal and the freever- 

 itcal movements of the coffin-bone, hammering and bruising 

 the vascular structures coming between the heel of the coffin- 

 bone and the iron heel of the shoe. The elements of the 

 theory were an active and a passive agent, and sensitive tissues 

 suffering between them. The illustration of the theory was 

 irresistable ! An anvil, a hammer, the active agents. The 

 iron shoe was the passive agent, the anvil ; the coffin-bone 

 represented the active element, the hammer, which was wielded 

 by the motive power of the foot, and the sensitive structures 

 the thing hammered and bruised between them. It seems a 

 pity almost to spoil such a theory, but facts are inexorable ; 

 and from a logical conclusion there is no escape, if the conclu- 

 sion is a sound one. 



THE WRITER'S THEORY. 



The facts are that the seat of corn is close to the angle of
