THE HISTORY OF GLANDERS.

nostril, unaccompanied by fetor, with a circumscribed immoveable 
tumour under the jaw on the same side. In some cases, however, 
the flux comes from both nostrils : here, commonly, both sets of 
glands are tumefied, the nature of which swellings will serve to 
direct the diagnosis; in addition to which, most probably, the 
animal’s health continues good, and the discharge is not offensive. 
But, if cough be present with such a discharge, the submaxillary 
tumefaction uniformly diffused between the sides of the jaw, and 
there are feverish symptoms and evident impairment of the general 
health, the lungs are probably in this case the seat of disease. 
Still, in order that we may be certain about the existence of chronic 
glanders, we have no occasion to implicitly rely even upon these 
signs, for we may at once decide the point by the test of practical 
investigation. We have only to perforate (with a spill-gimlet) 
the frontal sinuses, and inject some clean tepid water into them: 
should the sinuses be healthy interiorly, the fluid will run from the 
nose either limpid as it was thrown in, or merely be tinged with 
blood; whereas, in a case of disease there, the water will carry 
down with it the matter lodged in the cavities. It is not uncommon, 
in chronic glanders, to observe a horse discharging profusely for 
several days, and then suddenly to cease running altogether. This 
arises either from inspissation of the matter collected, or from the 
effusion of adhesive matter within the sinus, which settles at the 
bottom of the cavity, and plugs up the aperture by which it com- 
municates with the chamber of the nose. During the interval of 
suspension no sign of disease remains but the submaxillary tume- 
faction ; there is no discharge, and consequently there can be no 
source of contagion ; but, the collection of matter continually aug- 
menting, at length the plug is forced out, and the flux returns with 
more virulence than ever. In Smithfield, it used to be a common 
cheat to sell a horse having this disease for a sound one ; the trick 
consisting in stopping up the nostril of the affected side with a piece 
of sponge, which, of course, received and imbibed the discharge.” 
“ Though we have no specific remedy for chronic glanders, no 
more than we have for acute, the Professor has seen more cases of 
recovery from this than from the latter disease. When the dis- 
charge early in this affection becomes profuse, and continues long 
so, it will end, every now and then, in a spontaneous cure, as is 
the case so often with gonorrhoea : at other times, the flux will 
persist and run for years, and the horse, so long as the disease 
continues chronic, maintain his full health. Many horses of this 
description are to be found in various parts of the country working 
in road waggons, brick carts, farmers’ establishments, &c. Not- 
withstanding that the disease is not only incurable, but is con- 
tagious. The matter emitted from the nose of a horse having
