are killed. Used in this way mallein seems to have 

 a curative effect on incipient cases, and has been 

 very successfully used in freeing infected stables 

 from the disease. When a horse is killed because 

 it has glanders or farcy the stall should be thor- 

 oughly disinfected where it has been kept, as well 

 as the harness, blankets, currycomb and other 

 utensils, and anything that cannot be easily disin- 

 fected ought to be destroyed. Public watering 

 troughs where the horse has been watered should be 

 emptied and cleaned out, and the blacksmith ought 

 to disinfect his shop where the horse was shod. 



There are various diseases that may be taken for 

 glanders or farcy, and there have also been numer- 

 ous instances where glanders has been taken for 

 something else ; for instance, chronic nasal catarrh. 

 What many old-time veterinarians used to call 

 chronic nasal catarrh or nasal gleet, were, in many 

 instances, if not in nearly all, cases of chronic 

 glanders, and when one of these cases of nasal 

 gleet was rounded up in a locality, glanders disap- 

 peared in that neighborhood 



A horse with a chronic discharge from the nose 

 as the result of a decayed tooth may sometimes be 

 mistaken for a case of glanders, and also a horse 

 with distemper or strangles ; but the latter generally 

 recovers soon, and in strangles the gland under the 

 jaw softens and breaks and discharges while in 

 glanders the gland remains firm and hard and gen- 

 erally not sensitive to manipulation. 



There is a disease that has been troublesome m 

 Pennsylvania and parts of Ohio the last two years 

 called suppurative lymphangitis or epizootic lym- 

 phangitis, which may be mistaken for farcy, but 

 animals suffering from it do not react to mallein, 

 and guinea pigs inoculated with the discharges do
