DIAGNOSIS OF GLANDKRS. 175 



Tho suspicious accompaniments of these two symptoms are, the 

 absence of any concomitant catarrhal indication, the horse having 

 been slightly " amiss," but now appearing as well as ever again : 

 the constancy and uniformity of the one-sided discharge ; the cir- 

 cumscribed or defined nature of the submaxillary tumour, together 

 with its proximity, perhaps attachment, to the jaw-bone ; the 

 duration of the two symptoms in question, without any material 

 alteration for better or for worse ; lastly, the horse being in his 

 adult or an aged period of life. It is quite possible the dis- 

 charge may issue from both nostrils, and submaxillary tumours 

 appear on both sides as well ; and so will the case be rendered 

 more like catarrh, and yet have enough about it to engender in 

 our mind suspicions of glanders. In fact, it may positively be 

 glanders, either in an incipient or an insidious form, or in a chronic 

 stage. No prudent practitioner, however, would go the length, 

 on mere inspection, to pronounce on the case ; although he would 

 consider it his duty to segregate such a horse from his companions, 

 and place him in a situation where there could be no possibility of 

 communication, mediate or immediate, between him and sound 

 horses. Attentive observation and appropriate treatment will, 

 after no very great elapse of time, demonstrate whether the case 

 be catarrhal or not : but if not catarrh, what is it, or what can it 

 be] Is it nasal gleet 1 If so considered, let such treatment as is 

 proper for nasal gleet* be adopted, and for a reasonable time perse- 

 vered in, under a hope that it may cease or " run itself dry ;" 

 still using all precautions to prevent communication with sound 

 horses as much as if we were assured we were actually treating 

 glanders itself. Time, I say again, must and will unravel the 

 secret. If this cannot be or has already been given, we are at 

 liberty to resort at once either to the test of examining — through 

 an operation to be hereafter described — the sinuses of the head, or 

 to that of inoculation. The supervention of chancre in the nose, 

 or of any indication of farcy in any part of the body, would, of 

 course, decide the question at once. 



With Strangles in its early stage it is possible, though not 

 by an experienced hand probable, glanders may be confounded.
