216 CAUSES OF GLANDERS. 



like other poisons, is governed by laws peculiar to itself, and that 

 this is still further proved by introducing blood from a glandered 

 horse into the veins of a healthy ass, and similar symptoms pro- 

 duced, I am prepared to prove that UNHEALTHY BLOOD taken 

 from an animal NOT GLANDERED will produce similar effects as 

 blood taken from a glandered horse. In the course of my experi- 

 ments / have produced glanders and farcy with a considerable 

 tuberculous disease of the lungs, and water in the chest, that 

 ended in death, in the course of ten days, by introducing half a 

 jnnt of blood, taken from a rabid dog, into the jugular vein of a 

 five-year-old healthy ass ; and similar effects will likewise follow 

 the introduction of any irritating fluid into the circulation — as a 

 solution of copper." (P. 160.) This clearly shews that it is the 

 particular irritation to which the system of some animals is so sus- 

 ceptible (no matter from what cause) that produces the diseased 

 symptoms, and that it is not the effect of a specific or particular 

 jooison contained in the blood." (P. 161.) Mr. Vines adds, he has 

 seen " glanders, and even death, produced by inoculating an ass 

 with matter taken from an unhealthy animal labouring under 

 virulent grease." (P. 161). ''Many of our present practitioners 

 believe that glanders cannot be communicated from one animal to 

 another through the medium of the breath or exhalations of the body, 

 but that it requires the actual contact of glandered or farcied matter to 

 produce an effect. In these views, then, I perfectly coincide, never 

 having seen a single case ivhich could be fairly attributed to infec- 

 tion, through any inhalation from another horse." (P. 166.) — " I find 

 that the contagiousness, by which I mean the actual contact of 

 matter, both of glanders and farcy, admits of various modifications : 

 for instance, in those animals where the system is in the inost UN- 

 HEALTHY STATE the discharges or matter will be of the most con- 

 tagious character, and so on the reverse." (P. 166.) " Strong, 

 healthy, well-fed horses are by far the least susceptible of inocula- 

 tion by morbid matter ; while, on the contrary, those animals which 

 are but badly fed, and out of condition, especially asses — whose 

 systems are always weak — are the most susceptible and liable to 

 become affected, and generally die about eight or ten days after 

 inoculation." (P. 166.) Mr. IMonk, a well-known horse slaughterer
