THE IMPROVED ART OF FARRIERY. 97 



the mucous membrane, which lies in the upper part of 

 the throat, the windpipe and the bronchial tubes, 

 sometimes extending to the lungs, and these are always 

 more or less inflamed. There are two kinds of Stran- 

 gles, denominated true and false : in the first, the ge- 

 neral appearance is much more healthy than in the 

 latter, and does not so frequently degenerate into 

 Glanders. The healthy, or true strangles, through 

 maltreatment, often becomes in time converted into the 

 false ; but this last species never assumes the form of 

 the first 



Causes. — Authors on this subject differ materially. 

 Impurities in the body, imbibed from eating pernicious 

 food — change of diet — cold, are generally assumed as 

 the causes ; while some assert, that from its affecting 

 colts and young horses it may be considered as consti- 

 tutional ; for when once attacked, (and horses are ge- 

 nerally afflicted with it when young,) they are not sub- 

 jected to it a second time. The disease oftentimes 

 produces very little interruption to the health, espe- 

 cially when the v/eather is fine ; although, in other 

 cases, the horse has been reduced to a state of complete 

 emaciation, and thus has frequently terminated in 

 Glanders. M. Rodet, of the Royal Alfort Veterinary 

 College, wrote on this subject very ably. In the 

 Farriers' and Naturalists' Journal for July, 1828, ap- 

 peared the following translation of a part of that 

 work : —

 circulates in the blood, until nature makes an effort to 

 throw it off, and it settles on a part, which is usually
