GLANDERS AND FARCY. 257 



520. Propagation of Glanders and Farcy. 



Very little is known respecting the precise nature of the virus. Suf- 

 fice it to say that it can be communicated to healthy animals by inocula- 

 tion or by contagion and probably by infection. Hence, in order to 

 avoid risk, any suspected animal should be removed to an isolated loos 

 box ; and all the horses occupying the same stable should be subjected to 

 the closest supervision. The man, who looks after the horse under ^sus- 

 picion should not be allowed to go among the other horses. The whole 

 of the grooming articles, stable equipment, clothing, saddlery etc., must 

 be kept quite distinct. The attendant should be particularly warned, 

 that the disease is communicable 'to man and fatal. 



521. Difference in the primary seat of Glanders and Farcy. 



Both Glanders and Farcy are diseases of the absorbent system. In 

 veterinary treatises it is commonly said that in glanders the deep-seated 

 absorbents of the anterior extremities are primarily affected ; whilst in 

 farcy the superficial absorbents of the hind extremities are the early seat 

 of the disease. 



This definition is hardly correct as regards farcy. Farcy is very un- 

 certain in the point of its appearance, and is found almost as frequently 

 in the anterior as in the. posterior parts. The outward development of 

 the constitutional disease generally seems to be determined by the occur- 

 rence of any abrasion in any part of the body. 



The hind legs from kicking, from cracked heels, and from, various 

 causes are no doubt more liable to abrasions and superficial inflammation 

 than other parts, and hence perhaps we most frequently find the primary 

 development of farcy in them. In harness horses, however, we often find 

 it on the neck, which is liable to be chafed by the collar, or on the ribs 

 from rubbing of the traces or pole. In all horses it is common on the 

 lips, probably from abrasions or at least irritability of the skin caused 

 by the bit. 



Glanders, on the other hand, invariably appears in or about the head, 

 and is primarily indicated by swelling of the glands under the jaw and 

 by a discharge usually from one nostril only in the early stage or 

 during the chronic phase of the disease. 



521a. Glanders and Farcy. Acute and Chronic. 



These diseases may be present in an acute or in a chronic form. In 

 veterinary works the symptoms of each are usually described separately. 

 But it will probably be sufficient to give the general features which are 

 most frequently seen, and which are quite enough to enable the reader 

 to recognise the diseases. 



522. Symptoms of Farcy : 



The attack is usually ushered in with febrile disturbance ; but at other 

 times this symptom, though probably not altogether absent, may be so
