GLANDERS Glanders affects mostly the equine (horse, 



ass and mule) family; there is no cure for the 

 disease. It is a very dangerous disease, as it is 

 often transmitted to the human. A horse that 

 lias a chronic discharge from the nose and does 

 not seem to be thriving, needs attention at once, 

 and the fact should immediately be reported to 

 the State authorities. The mallein test is given 

 to be sure of the disease. The animals are con- 

 demned and destroyed. In some States the Leg- 

 islatures reimburse the owner in part, at least, 

 for loss from glanders.
