THEIR PATHOLOGY, DIAGNOSIS, AND TREATMENT. 43 



becoming foal, offensive, and abhorrent. The ulcers formed are de- 

 pressed in the centre with raised ragged edges of fungoid growth difficult 

 to heal. It is a usual practice to burn them with the budding iron, 

 and, after the slough caused by this has come off, to dress with a strong 

 solution of corrosive sublimate or pure carbolic acid and glycerine, one 

 part of the former to two of the latter. The buds or buttons are often 

 subjected to the treatment of the iron before they break. In some few 

 cases these farcy lumps become very hard, and remain so for many months, 

 lulling the unsuspicious into a dangerous carelessness; but the evil, 

 although dormant for the time, is sure sooner or later to break out with 

 renewed force. 



There is great danger of the ignorant and inexperienced mi&taking 

 farcy buttons for the lump3 that appear in surfeit, but, in the latter, 

 they spread over the body, and are never connected by the hardened 

 cord-like vessels noticed as peculiarly indicative of farcy. The eruptions 

 in surfeit are pustular, and do not end in unhealthy ulcers, but in 

 desquamation, or peeling off of the cuticle. 



In some cases the legs swell enormously; a hinder leg being generally 

 attacked. The swelling takes place very suddenly, and the whole leg, from 

 hock to thigh, may become three times its ordinary size. This is accom- 

 panied by feverishness ; but these symptoms need not be mistaken for 

 grease, with which they are apt to be confounded ; for in grease there is 

 not only redness of the skin, but it is stretched rigidly, and there is 

 always scurf and cracks. 



In other cases the muzzle swells considerably, and this is generally 

 followed by a discharge of offensive matter from the nose. The horse 

 becomes mangy and hide bound. Other general symptoms of farcy are 

 the appetite failing or, on Vaq other hand, being extremely voracious. 

 Intense thirst i3 also generally present. 



Before mentioning the causes giving ris9 to farcy, or the methods of 

 cure adopted, it will be more convenient to refer to glanders. 



Glanders, as already observed, is so very intimately connected with 

 farcy that they cannot easily be separated, and are by many looked on 

 as different stages and phases of the same disease. In the first stage of 

 glanders there is a continuous discharge of thin, watery, transparent 

 matter, from one or both nostrils, but generally from one only, and that in 

 the vast majority of cases the left, a most singular fact, which has not 

 been accounted for. This discharge is distinguished from that of common 

 cold by its chronic character, as it may continue unchanged for many 

 months without affecting the general health of the horse ; yet in this 

 stage the disease is infectious, showing what great care is necessary to 

 distinguish it, and by isolation prevent the spread of so dire a malady. 

 During this first stage the discharge is small and constant, and never 

 sticky, and is free from smell. And if with these features the dischargo 

 is confined to one nostril, the disease is certainly glanders. 



In the second stage the discharge considerably increases, becoming
