THE HORSE IN SICKNESS AND DISEASE 2G7 



of the disorder, in whatever manner it may be produced. 

 For if such cruel and foolish treatment of horses does not 

 produce glanders and farcy, it produces other disorders 

 which are often more speedily fatal than glanders ; and 

 if it does not actually produce a disorder, it weakens the 

 constitution to such a degree that the animal is rendered 

 more susceptible of the contagion of glanders, as w^ell as of 

 other diseases. It is from this cause that glanders spreads 

 so rapidly amongst post and stage-coach horses, while among 

 horses of a different description its progress is generally 

 slow. 



It is a remarkable circumstance that glanders cannot be 

 communicated by applying the matter which is discharged 

 from the nose of a glandered horse to the nostrils of a 

 sound horse, unless there be an open wound or sore, even 

 though a piece of lint soaked in the matter be put up the 

 nostrils, and kept in contact with the pituitary membrane 

 for a short time, or even if the matter be thrown up the 

 nostrils with a syringe ; but if the smallest quantity of 

 matter be applied in the way of inoculation, either to the 

 membrane of the nostrils or to any part of the body, a 

 glanderous ulcer will be produced, from which farcy buds 

 and corded lymphatics will proceed. After a few weeks 

 the poison will get into the circulation, and the horse will 

 be completely glandered. The circumstance of glanders 

 not being communicated by applying matter to the nostril 

 enables us to account for a horse escaping the disorder, as 

 he sometimes does, after being put into a glandered stable 

 or standing by the side of a glandered horse. Glanders, 

 however, is frequently communicated by (accidental) inocu- 

 lation ; and there is only one other way in which it can be 

 communicated, that is, by swallowing the matter which 

 flows from the nose of a glandered horse. 



A horse affected with glanders may inoculate himself, 

 and thereby produce the farcy. This has happened to 

 horses while at grass. The horse has an itching in the 

 hind leg, which leads him to rub and bite the part, and at 

 the same time rub on it the glanderous matter which 

 flows from his nostril. The possibility of this circumstance 

 taking place may be easily proved by inoculating a glan- 

 dered horse, in any part of his body, with some of his own 

 matter. There are many ways in which a sound horse 

 may be accidentally inoculated with the matter of glanders,
