THE HORSE, DISEASES OF THE NASAL GLANDS, ETC. 29T 



There are some symptoms that may be observed, even before th« 

 appearance of any discharge whatever ; and these may be described, 

 though they may sometimes prove faUacious, and are found to be but 

 extraordinary indications of some other disease. 



The first signs are those of heaviness, dulhiess, followed by fever ; the 

 eyes are red and unhealthy looking, while the light is seemingly painful to 

 them. The hair is one day dry, the next, perhaps, it resumes its natural 

 appearance, and so alternating until after awhile it becomes staring and 

 unnatural. The flesh wastes away rapidly for a time ; then, and particu- 

 larly if a change of food is introduced, showing some improvement, and 

 so alternating till at length he begins to show signs of permanently 

 failing health and of a general debility. 



These may be regarded as for the most part premonitory signs, and up 

 to this time there may be no appearance of tumors and no discharge 

 from the nostrils ; but the animal should be subjected to the most rigid 

 scrutiny, to discover whether there is anything to confirm the impression 

 made by the symptoms enumerated as to the probable existence of glan- 

 dered condition. 



After these manifestations there may be said to be three stages of the 

 disease, the jDeculiarities of each of which, in so far as they are distinctly 

 defined, are generally as follows : In the first stage the discharge so 

 much resembles that which attends some other nasal affection as some- 

 times to pass unnoticed, but examination will disclose a curious fact 

 which has not been accounted for, — it will be found confined to one 

 nostril, and that, in the vast majority of cases, the left. Occasionally it 

 is the right, very seldom both. This, however, must not be regarded as 

 a peculiarity of the first only, as it is common to every stage of the 

 disease. 



The second stage is characterized by an increased flow, and it also 

 becomes more mucous and sticky, while its color changes from an almost 

 transparent clearness to a whitish or 3^ellowish tinge. It often begins 

 now to drip from the nose in stringy clots. Some of the matter in this 

 stage, now more actively poisonous, being taken up by the absorbent.*, 

 affects the neighboring glands. If both nostrils are discharging, the 

 glands within the under jaw will be enlarged on both sides ; if from on« 

 nostril, only the gland on that side. As other diseases will produce 

 these swelled glands, as catarrh, for instance, it becomes necessary to 

 look for some peculiarity in order to determine certainly as to the exist- 

 ence of glanders. At first the enlargement may be spread over so mucr^ 

 Burface as not to make any distinctly marked lumps ; but this soon 

 changes, and one or two small swellings remain, and these are not in the 

 center of the channel, but adhere close to the jaw on the affected side.
