108 ARTISTIC HORSE-SIIOEmG. 



even into the chest ; and, at last, the whole cellular mem- 

 brane and lymphatic glands become one mass of disease, 

 finally wearing- down the horse by irritative fever. This 

 is the regular course which will occur in most cases ; but 

 there are numerous exceptions, in which farcy breaks out 

 suddenly without any warning- of these small and insidious 

 steps, and the ulcerations run their course more rapidly 

 than I have here described them. With regard to the 

 identity of the two diseases, there can, I think, be little 

 doubt on the matter, when it has so often been demon- 

 strated by inoculation that the matter of either will produce 

 a primary sore in the shape of glanders, followed by 

 secondary ulcers in the shape of farc3^ The latter disease, 

 when inoculated into the system of another horse, does 

 not at once reproduce its own likeness, but only bA^ means 

 of aglandered ulcer of the nose, or of any other part in which 

 it is inserted. If it is inserted in the skin, it is some time 

 in breaking out into ulcers, and it does not always succeed ; 

 but finally the secondary symptoms appear just as if it 

 were introduced into the Schneiderian membrane ; hence, 

 it is reasonable to conclude that the two are identical, and 

 that the analogy with S3q3hilis is complete. Farc}^ is dis- 

 tinguished from several other diseases which resemble it 

 by the following signs : 



From Grease it ma^^ be known when it attacks the legs, 

 by the inflammation being less acute, though the swelling 

 is often more sudden, but the redness and glossiness are 

 not so great ; also b3^ the following symptoms given in the 

 table herewith :
