CHAP. III.] DISTINCTIONS TO BE OBSERVED. 371 



the glands remains) upon changing to country 

 quarters, or to a succession of regular living and 

 regular work. 



Symptoms. — No cough accompanies real glan- 

 ders in any of its stages ; and this, though a ne- 

 gative piece of information, shall be taken as a 

 good and positive criterion that must not be neg- 

 lected: a running may make its appearance, as it 

 does at the left nostril usually, in the glanders, 

 and the glands may adhere to the jaw-bone, as they 

 do in real glanders, but no cough accompanies these 

 symptoms of glanders. When cough supervenes, 

 the disease may be a catarrh, or a consumption, 

 the asthma, or strangles, but these are not con- 

 tagious, unless they last a long time, and adhesion 

 of the glands takes place : in these last mentioned 

 disorders the discharge commonly proceeds from 

 both nostrils alike; whereas, the running in in- 

 cipient glanders is confined to the left nostril *, 

 and the gland of one side only is then affected. 

 Mind that. 



As the disorder proceeds, it affects both sides 

 alike ; chancres appear all over the pituitary mem- 

 brane, occasioned by the corrosive nature of the 

 discharge. This assumes a different appearance 

 as the constitution of the individual may have been 

 more or less gross or vitiated : the appearance or 

 quality of the discharge differs also, according to 



* Of eight hundred cases of glanders that came under the notice 

 of Mr. Dupuy, only one horse was affected in the right nostril.
