104 GLANDERS GENERATED. [BOOK I. 



black as one's hat, infects the other lobe, and morti- 

 fication ensues, which is rather accelerated by the 

 cordials with which the poor creature is usually 

 punished, and it dies. 



But when it so happens that too much of the oily 

 fluid is secreted in the wind-pipe, as is the case 

 with well-conditioned and otherwise healthy horses 

 attacked with slight colds, the animal snorts or 

 coughs ■ it off by a sudden natural effort ; wherein, 

 the midriff being made to press forcibly upon the

 the horse has been put beyond his due lengths, 

 at his utmost pace. Whenever this is the case, the 

 membrane that lines the nose inside becomes irri-

 thickened a little, is the consequence ; inflammation 

 of the part, ulcers, and a running of foul matter 

 ensue — and this, if the blood be not in a good state, 

 soon becomes that obstinate malady — the glanders. 

 Horses of good condition never contract the glan-

 good keep will generally cause glanders to run off. 



An instructive experiment may be made upon the 

 jrfuck of a sheep — the relative situation and func-

 those of the horse, are not so long in proportion to 

 their thickness. Take a pair of bellows, and hav-
