Chest affections in horses bear even a greater propor- 

 tion to the number of their other diseases than in our own 

 persons. Putting accidents and lamenesses out of the 

 question, we shall find a large majority of the cases pre- 

 sented to us for treatment to be diseases of the respiratory 

 apparatus ; and the most fatal of them to be those which 

 attack the lungs and their enveloping membrane, the pleura. 

 These diseases also evince in horses a rapidity of destruc- 

 tive course which is not so conspicuous in men. In our 

 bodies, they are rather apt^ by slow degrees, to bring their 

 victims to their end j while they will hurry horses off even 

 after but a few hours' duration, and in despite, too, of every 

 measure that medical skill can devise. This, of course, on 

 our part, calls for corresponding alertness and decision in our 

 therapeutics ; and the more so, seeing that it is not only re- 

 quired of us to save life, but to save organs, and in that 

 normal state too in which they may be so fit to carry on 

 their functions that the animal is able to do his work nearly 

 or quite as well as ever. If he be left with imperfections 

 in his wind, I am afraid we shall derive but little credit from 

 his cure, even though w'e may have been the means of 

 preserving his life. 



Predisposition to pulmonary disease is observed to exist 

 in horses of certain age, form, and temperament. Young
