GLANDEES AND FAECY. 2'^^ 



munlcate it in any one of its forms by compelling healthy 

 animals to inhale the expired air of those suffering from the 

 disease, whilst others maintain that it is both contagious and 

 infectious. The first opinion, if acted upon in every day prac- 

 tice, would, I opine, lead to disastrous results, and should not be 

 entertained ; for even if we were to grant that the virus is con- 

 tained in the discharges from the ulcers, numerous experiments 

 have proved that pus and other organised cells float in the 

 atmosphere ; the specific virus contained in these cells may 

 thus be easily conveyed from one animal to another. Again, it 

 must not be forgotten that in some instances glanders may 

 exist without any external manifestations, i.e., without discharge 

 from the nose, nor from farcy ulcers, but even in this form it is 

 capable of propagation. 



Farcied matter, made into balls, and introduced into the 

 stomach of a horse, has caus-^d glanders ; and whichever way the 

 virus has been introduced, once absorbed, it infects the whole 

 blood, as has been proved by the experiment of the late Professor 

 Coleman, who says — " I have produced the disease by first 

 removing the healthy blood from an ass until the animal was 

 nearly exhausted, and then transferring from a glandered horse 

 blood from the carotid artery into the jugular vein of the ass. 

 The disease in the ass was rapid and violent in degree; and 

 from this animal, by inoculation, I produced both glanders and 

 farcy." Professor Coleman also experimented on asses with virus 

 obtained from man. He directed two asses to be inoculated 

 with matter taken from the arm of a man labouring under the 

 malady, which resulted from a puncture received in dissecting 

 a glandered horse, and both asses died of glanders. These 

 experiments have been repeated, and similar results obtained 

 by Girard, Hering, and Leblanc. 



Period of inciibation. — Like all morbid poisons, that of glan- 

 ders has its period of latency, which is, however, generally short. 

 In the ass, the submaxillary glands become swollen and tender 

 the second or third day after inoculation, and a discharge from 

 the nostril occurs from the third to the sixth day. In some 

 instances the incubation is much longer — from one to three or 

 even six weeks ; one case is mentioned in the Froch-verbal de 

 r Ecole de Lyons where the disease did not appear till the end of 

 the third month after inoculation. The matter in this instance
