188 VARIETIES OF GLANDERS. 



to the exclusion even of the latter — a very rare case I believe — 

 sooner or later we shall detect the miliary ulceration, the only 

 ulceration present in this form of disease, and therefore one truly 

 characteristic of it. 



Chronic glanders appears sometimes as the sequel of other dis- 

 ease in the air-passages and lungs ; it is more commonly, however, 

 an idiopathic disease, and one that differs, as much as one variety 

 of disease can be different from another, from the acute and sub- 

 acute affections : between the latter there is but a difference of 

 intensity, whereas the former, be it remembered, exhibits pathologi- 

 cal differences. It mostly attacks its victim in a mild and masked 

 form. The horse is thought to have caught cold, and no suspicion, 

 perhaps, is aroused to the contrary until it comes to be discovered that 

 this " cold" is lasting a great while longer than it ought to endure, 

 and that it has resisted all the common means of cure. The horse's 

 spirits and looks and appetite are not in the slightest degree im- 

 paired ; he works — or would work — as cheerfully as ever ; but all 

 the time he has a discharge from one nostril, with an enlargement 

 of the submaxillary lymphatic gland or glands of the same side. 

 And although the nasal issue may be of a nature of itself to excite 

 suspicion, and the enlargement may be such as appears to strengthen 

 or confirm this suspicion, yet do cases incipient in their nature too 

 often present themselves, in which it is impossible for any practi- 

 tioner, from these appearances alone, to determine at once on the 

 nature of the attack. Give time, and the veterinary surgeon, by 

 watching the progress of the case, will be enabled to solve the 

 mystery, and at length to demonstrate beyond any doubt the real 

 nature of the animal's ailment. 



Insidtous Glanders. — Under this happily-chosen appellation 

 my friend and schoolfellow, Mr. James Turner, has, in a paper he 

 read to the Veterinary Society on the subject, in 1830, described, 

 with his usual accuracy of observation, the stealthy signs by 

 which we may apprehend the approach, or rather suspect the 

 existence of chronic glanders in its early or masked form. He 

 with truth characterises it as commencing "in a watery discharge 

 from one or both nostrils, more frequently from one only, gene- 

 rally containing particles of mucus or pus, at other times assuming 

 the appearance of both ; invariably in small (Quantities, but never
