58 GLANDERS. 



three years. There may be no cough ; no loss of 

 appetite; no apparent illness of any kind; scarcely 

 any enlargement of the glands beneath the lower jaw; 

 yet the horse shall be glandered, and capable of com- 

 municating the infection. 



By degrees the disease proceeds. The discharge 

 becomes decidedly, although to a very slight extent, 

 increased; but it is still watery and transparent, and 

 is to be distinguished from the natural secretion only 

 by a slight degree of stickiness when it is rubbed 

 between the fingers. It is also distinguished from 

 the discharge of catarrh by its being constant ; not at 

 one time almost ceasing, and at another being poured 

 forth in large quantities. The glands beneath the 

 jaw sympathize with the membrane of the nose ; they 

 enlarge, and the horse is what the stableman calls 

 iugged. The kernels may swell in catarrh ; but the 

 enlargement characteristic of glanders is distinguished 

 by the glands not being tender ; and still more par- 

 ticularly by the glands seeming to adhere to the inner 

 side of the jaw r -bone. They are hard, and the altered 

 condition which they exhibit is unattended by any 

 enlargement of the surrounding parts. 



By degrees the discharge increases ; it becomes 

 more adhesiv r e ; it sticks about the nostril ; it is still 

 often confined to one nostril, and the hardened gland 

 is found on that side alone. It is now, perhaps, 

 recognized for the first time, by the owner of the 

 horse or his servants ; but the mischief has been done 

 — it is highly probable that no medical care can now 

 save the animal, and he may have propagated the 

 disease among his companions.
