 caufed by an inflammation of the throat, I found 

 that it was caufed by a defluxion upon the tra- 

 chea; which appeared to be the effect of a quin- 

 zy ; this diforder lafls two or three days andfome- 

 times longer ; the horfe can fcarce eat or drink, 

 and it is known by a fmall fwelling under the 

 throat, which is fenfible to the touch. 



A horfe difcharged a great quantity of white 

 thick matter by the nofe for eighteen months ; 

 and when he was at reft in the liable the run- 

 ing flopped ; but he was heard to rattle, which 

 alfo ceafed when they made him work -, how- 

 ever although he was not affected in the glands 

 they knocked him on the head. I opened him 

 and found the pituitary membrane perfectly 

 found, the flnus and all the internal parts of 

 the nofe well, the vifcera in the abdomen found; 

 but upon opening the thorax, I found a consi- 

 derable abfcefs, where the trachea divides to 

 fink into the fubflance of the lungs. 



By this obfervation it is plain a horfe may 

 live and work a long while with an abfcefs in 

 the thorax; and yet the pituitary membranes 

 may remain uninjured by the matter paffing by 

 the trachea, crofs the nafal cavities ; and 

 that we mufl diftinguifh this from a true 

 glanders, by the ratling, tumefied glands, 

 and the vaft quantity of matter that runs 

 off.
