VARIETIES OF GLANDERS. 191 



not under the jaw, the submaxillary feeling of lumpiness having undergone 

 no alteration. In this state the mare continued for a fortnight, during which 

 period she kept discharging pretty profusely from the off nostril, without 

 shewing the slightest sign of any issue from the near ; retaining her appetite 

 and spirits, and only coughing now and then, without shewing any sign what- 

 ever of soreness of throat with it. During the third week I had her 

 nostrils steamed with the vapour of hot water, with a view of eliciting a more 

 copious discharge, and it appeared to have that effect ; at the same time 

 I ordered her diet to be changed from bran-mashes only to two feeds 

 of corn, daily. On the eighteenth day her discharges, which under the ope- 

 ration of the steaming had first been augmented, were evidently reduced in 

 quantity ; on the nineteenth, a further reduction was perceptible ; and on 

 the twenty-first she was free from any running whatever ; in fact, she was 

 in appearance quite well again, though still (according to the man's account) 

 keeping the occasional cough. 



The foregoing case is instructive to us from its shewing how 

 closely coryza or simple catarrh (which it was), may resemble 

 insidious glanders, confined as the nasal flux was during the whole 

 while to one side : the attendant cough, however, though it was 

 but occasional, was favourable, and moreover there was no very 

 distinct glandular tumefaction. The unfavourable symptoms being, 

 the haemorrhage from the nose, the offensive character of the dis- 

 charge at one time, and the continuance of it from one to the 

 exclusion of the other nostril. 



In Duration hardly any disease can be more uncertain than 

 chronic glanders. It may continue, simply as a discharge from one 

 nostril, accompanied by submaxillary glandular enlargement, with 

 very little or unimportant variation in either, for months — nay, for 

 years : on the other hand, it may run into the acute in as many weeks. 

 Any person, therefore, having a horse of this description in his pos- 

 session can at no period say how long it may be before the disorder 

 may shew itself in an active, nay rapidly destructive form. In 

 some cases the nasal flux, as I said before, runs for a long period 

 with but slight or unimportant alteration ; in others, in quality as 

 well as quantity, it exhibits most remarkable fluctuations ; at one 

 time appearing so scanty and trifling as hardly to be worth notice ; 

 at another, pouring forth in all the abundance of the eruption of 

 pent-up channels, bringing in its current matters solid as well as 

 fluid, from the admixture of lymph with muco or sero-purulent
