214 CAUSES or GLANDERS. 



dered ; but no sooner had this troop left the stable than the disease disap- 

 peared from among them ; but still continued its ravages in the troop that 

 succeeded it imtil the 18th January, 1805, when the glass windows fixed 

 above the doors were taken down, and lower ones put up in their stead ; and 

 four large tubes, two on each side, were at the same time introduced into the 

 wall, which tubes ascended obliquely through the roofs of the shed- stables. 

 Six points of communication with the atmosphere being thus opened, the 

 cause of the disease was removed ; and though the same troop continued to 

 occupy the stable until the 29th of July following, its baneful influence never 

 re-appeared." 



''The foregoing statement," concludes Mr. Smith, ''requires no 

 comment." "The disease not accompanying the first troop when it 

 left the stable, and its progress being arrested in the second troop, 

 bv removing, through the means of ventilation, the cause which 

 produced it, added to the circumstance of its never appearing again 

 during the time the troop continued there, are facts which every 

 one will be able fully to appreciate*." 



RODET, 1830, Professor at the Royal Veterinary School at 

 Toulouse, and formerly Veterinarian in Chief to the Hussars of 

 the Royal Guard, in reference to the regiments of which he has 

 had the veterinary superintendance, alleges the general predis- 

 posing causes of glanders to be, the fatigue, the privations, the ex- 

 cesses, the sudden and frequent changes experienced by military 

 horses in campaigns." " In regard to remount (young) horses, the 

 principal predisposing causes are, a strong predisposition to diseases 

 of the lymphatic system, having its source or origin in a tempera- 

 ment eminently lymphatic, as is observable in horses with short 

 heads, slender necks, flat sides, narrow chests, and contracted 

 shoulders ;" — " castration practised without proper precautions, at 

 a time of difficult dentition, or while they are spreading in growth ; 

 lastly, and especially, at the period they are experiencing sudden 

 changes of living, in food and grooming, country, regimen," &c. 

 " Last of all, forage of bad quality." " Contagion can but rarely 

 be regarded as the cause of glanders in the army, since every pre- 

 caution is taken to guard against it. It cannot be considered either 

 as a proximate, or as the most frequent or the most ordinary cause,
