358 GLANDERS. 



hair feels dry, and falls off on being handled ; the matter 

 from the nose increases in quantity, becomes sanious, 

 stinking, or bloody, and is coughed up by the mouth also ; 

 the animal has a bloated aspect ; the cellular tissue pits ; 

 the conjunctiva is infiltrated ; the caruncula lachrymalis 

 grows discoloured ; the eye has the expression of a sheep 

 suffering from the rot, and the gums are pallid. If put to 

 hard work, such horses rapidly decline in condition ; and 

 yet, should they be destroyed, fat is found in abundance 

 upon their bellies and about their hearts. 



From the very serious effects which follow the spreading 

 of this disease, the veterinary practitioner is often called 

 upon to give a prompt and definite opinion relative to it. 

 The principal intricacy that will present itself, arises from 

 the similarity of appearance that frequently exists between 

 the true disease and a diseased and increased muco-puru- 

 lent secretion which sometimes remains after a severe cold, 

 or is the consequence of repeated catarrhal attacks. Local 

 inflammations also, from various causes, occasionally take 

 place within the nasal sinuses ; which although by no means 

 glanderous, yet are accompanied by such a regular and 

 continued flow of pus as to mislead the practitioner. In 

 such cases, however, the matter secreted is distinct from 

 the glairy pus of glanders ; and we may further be led 

 into a suspicion of the cause by the quantity of the dis- 

 charge, if the horse be allowed to feed from the ground, as 

 well as by the absence of visible ulceration. In present 

 colds the difficulty cannot be great, for then the general 

 health is commonly affected ; there is some fever, loss of 

 appetite, thirst, and cough, which are seldom so well 

 marked during the early stages of glanders ; and those 

 wbich are more advanced require but little to distinguish 

 them ; for although in catarrh the submaxillary glands are 

 sometimes sw^elled, yet they are in these cases hot also and 

 moveable. But when colds have been severe, or often re- 

 peated, there occasionally remains in the mucous mem- 

 branes of the air-passages, particularly in that of the nasal 

 cavities, a disposition to a morbidly increased secretion of 

 a muco-purulent nature, which will continue to flow from 

 one or both nostrils. We have seen cases of this kind which 

 have existed one or two years, and in one instance it had
