 BLOOD DISEASES. 



Arising from an Animal Poison — Highly Contagious, and producing the same 

 Disease by Inoculation — Farcy and Glanders. 



Farcy may be defined as an incipient form of 

 glanders, consisting of an animal poison, characterised 

 by corded swellings principally situated on the sides of 

 the neck, inside of the legs, &c, and further denoted by 

 rounded swellings at various intervals, and occasional 

 wounds from which these radiate. The cords are veins, 

 swollen as a result of the animal poison, the tumours are 

 further swellings preparing for abortive abscesses, and the 

 wounds are sloughing and widespreading ulcers, which 

 seldom heal, but discharge a thin sanious fluid. Such 

 an animal may live for years and determine the deaths of 

 many others, as well as the attendants. In some in- 

 stances, however, probably by an accumulation of the 

 original poison, or more correctly, by its development 

 according to the first cause, feverish symptoms arise, the 

 disease assumes an acute form, and the animal dies 

 under loathsome conditions. 



Glanders in a chronic form succeeds to chronic farcy, 

 and the animal lives on, a common danger to man and 

 beast. The system may have resisted the tendency to 

 the outward manifestations of farcy, as corded veins, &c, 

 but in their place the evidences of poisonous degeneracy 

 are to be found in a variable muco-purulent discharge 

 from the nostrils, sometimes only from one, and that the 

 left ; the corresponding glands beneath the jaws arc 

 swollen, hard and round, but not large, and ulcers pro- 

 bably are found to exist on the nasal membrane, some- 

 what high up in the cavity. The animal exhibits a 

 capricious appetite, but his condition may not be alto- 

 gether bad, and as he continues at work, suspicion is
