DISEASES AND THEIE TKEAT3IENT. 



Glanders and Farcy. 



I consider these difficulties mainly to enable the detection of 

 them to prevent their spreading, as they are extremely contagious 



to both men and horses. They are in- 

 curable, and to guard against the possibility 

 of danger when a case is suspected, the only 

 safe way is to at once either isolate or de- 

 stroy the animal. 



I depend mainly for my explanation of 



these diseases upon several old authors.* 



They fully agree with the statements of 



modern authors that it is practically useless 



to tamper with glanders. Farcy in its early 



stage can be controlled without difficulty,

 — usually the loft, sometimes the right, or even from both ; — the 

 discharge is clear and watery at first, becoming thicker and sticky, 

 accumulating around the nostril ; cough may be ])resent , but it is not 

 an invariable symptom. As it advances, the discharge increases, be-
