THE HORSE IN SICKNESS AND DISEASE 263 



the only sign by wliich we could discover it to be glanders 

 was by the glueyness of the matter." 



The forms of glanders, in modern books, are called acute, 

 sub-acute, and chronic. 



Acute Glanders results from inoculation or contagion of 

 the virus. This runs its deadly coarse, and includes typhoid 

 or putrid glanders. The course of acute glanders cannot be 

 better illustrated than by the following note from the cases 

 of Mr. John Field : 



" Mai/ 3rd — An ass was innoculated on both upper eye- 

 lids, both sides of the loins, the off* side of the withers, and 

 on the inside of the ala of each nostril, with the discharge 

 from the off" nostril of a grey gelding (purchased three 

 years previous), which was affected with this same glander-

 ever since. 



7th. — All the wounds suppurating except those on the

9tk. — Absorbents inflamed from the ulcers on eyelids 

 and back. 



14>th. — Absorbents much thickened, having diff'used in-

 that from the off* side of the withers to the breast, and, on 

 the eyelids, producing small fluctuating tumours on the 

 lugular vein, just below the ear; the alae nasi were beginning 

 to swell, and there was a snuffing in breathing, etc. 



Idth. — The alse nasi much thickened, copious discharge 

 from nostrils, and the swelling increasing. 



22ncl. — Respiration greatly embarrassed. He died on 

 the following day. 



Exarnination. — Much frothy spume in trachea — general 

 infiltration of lungs, which were inflamed — considerable 

 consolidation of the anterior and inferior portion of right 

 lobe — warty exculceration of Schneiderian membrane of 

 both nostrils to a greater extent than I had ever witnessed 

 before." 



Sub-acute Glanders is the variety of most ordinary occur- 

 rence. " It commences with the usual signs — slight or 

 otherwise — of indisposition ; and the disease may, though 

 the circumstance is a rare one, in the first instance assume 

 the acute type. Instead, however, of continuing its rapid
