enough, and one effort of the respiratory muscles is 

 sufficient for the purpose ; but when these cells have run 

 into each other, the cavity is so irregular, and contains so 

 many corners and blind pouches, that it is exceedingly 

 difficult to force it out again, and two efforts can scarcely 

 effect it. This disease is also accompanied by a dry and 

 husky cough of a peculiar sound, and is the consequence 

 of Thick- wind (;;?), and of those alterations of structure 

 consequent on inflammation (n). It is most decidedly an 

 UiisoiDidness (o). 



The division of the windpipe just before it enters the Bronchitis, 

 lungs, and the numerous vessels into which it immediately 

 afterwards branches out, are called the Broncliial tubes, 

 and the inflammation of the membrane that lines them 

 is called JJroiic/iifis. It is Catarrh (p), extending to the 

 entrance of the lungs, and is characterized by quicker and 

 harder breathing than Catarrh usually presents ; and by a 

 peculiar wheezing, which is relieved by the coughing up of

 part of the foot, and the sprouting of fungous matter 

 instead of it, occupying a portion of or even the whole of 

 the sole and frog. It is the occasional consequence of 

 bruise, puncture, corn {r), quitter («), and thrush {t). It is 

 extremely difficult to cure (u), and is an Unsoundness. 



Capped hocks may be produced by lying on an unevenly- Capped hocks, 

 paved stable, with a scanty supply of litter, or by kick- 

 ing (,r), in neither of which cases would they constitute 

 Uusoinuliiess, though in the latter they would be an indica- 

 tion of Vice ; but in the majority of instances they are 

 either the consequence of sprain in the hock, or are ac- 

 companied by enlargement of it, when they would be an 

 Unsoundness (y).
