GLANDERS AND FARCY. 227 



The following is the method of performing the inoculation : — 

 Cut off a little hair from the side of the neck or any other part 

 of the body, for about the space of half-a- crown; then take a 

 lancet and pass it under the cuticle or scarf-skin, for about a 

 quarter of an inch : it should not wound the skin much, but be 

 sufficiently deep to tinge the lancet with blood, or make one or 

 two drops of blood appear. The matter may be introduced into 

 this opening (first wiping off the blood) by means of a thin slip 

 of wood, of the form of a lancet. If the matter is glanderous, 

 the part will become sore in two or three days, and a scab will 

 form on it, which in a few days will be thrown off, leaving a 

 peculiar kind of ulcer, which will often spread rapidly, causing 

 a painful swelling of the adjacent parts, with corded lymphatics 

 and farcy buds. In about a fortnight, sometimes less, the 

 glanders will appear. No other matter will produce this effect. 

 There is only one kind of matter, besides that of glanders, 

 which, according to my experience, will produce any effect, and 

 that is the matter of virulent or chronic grease; when the dis- 

 charge from the heels is of a dark colour, something like dirty 

 kennel-water, and of a peculiarly offensive smell. (See Grease.) 

 When a horse is inoculated with this matter, a small but very 

 painful tumour will arise in the part. After a few days the 

 skin covering the tumour will become of a dark colour, and in a 

 few days more the dark-coloured skin will slough off, and leave 

 a healthy granulating sore, which will soon get well of its own 

 accord. A horse who had been thus inoculated, was inoculated 

 also with glanderous matter ; and it is worthy of remark, that 

 while the grease sore was going on, the glanderous inoculation 

 had no effect. 



The Nattire of Glanders. — [There is still much difference of 

 opinion as to the real nature of glanders. Professor Coleman 

 considered that it was a specific inflammation of the membrane 

 of the nostrils, produced by a poison in the blood, and on trans- 

 fusing the blood of a glandered horse into the veins of an ass, 

 it quickly communicated the disease, clearly pi-oving that the 

 blood was affected. Mr. Dupuy, who has written an elaborate 

 treatise on the disease, considers it to be of a tuberculous nature, 

 and that it is always preceded by tubercles in the lungs, that 

 is, small white grey bodies, which are principally composed of 

 carbonate of lime, but which, in time, are converted into pus. 

 These tubercles were, likewise, he asserts, found on the nasal 

 membrane. He considers that they may exist for several years 

 before the developement of glanders, and that ere this they 

 increase in number and coalesce, and at length are changed 

 into pus and occasion ulcers both in the lungs and the nasal 

 membrane. 



Professor Sewell in some measure coincides with these views,
