GLANDEKS OR FARCY. 157 



heart or in kidney trouble, aS in the last the swelling is cool and not 

 painful and the pitting on pressure remains for some time after the lat- 

 ter is withdrawn. It is not to be confounded with greasy heels. In 

 these the disease commences in the neighborhood of the pastern and 

 gradually extends up the leg, rarely passing beyond the neighborhood 

 of the hock. The swollen leg in glanders almost invariably swell's for 

 the entire length in a single night, or within a very short period. 

 When greasy heels are complicated by lymphangitis we have a condition 

 very much resembling that of farcy. The swelled leg in farcy is fre- 

 quently followed by an outbreak of farcy buttons arid ulcers over its 

 surface. In the entire horse the testacies are frequently swollen, hot 

 and sensitive to the touch, but they have no tendency to suppura- 

 tion. The acute inflammation is rapidly followed by the specific 

 induration which correspond to the local lesions in other parts of the 

 body. 



Chronic farcy in the ass and mule is an excessively rare condition, 

 but sometimes occurs. 



Chronic Glanders. In chronic glanders we have the same train 

 of inflammatory phenomena, varying in appearance from those of chronic 

 farcy only by the difference of the tissues in which they are located. 

 In chronic glanders we have first the tubercle, which is a small 

 node from the size of a shot to that of a small pea, which forms 

 in the mucous membranes of the respiratory tract. This may be 

 just inside of the wings of the nostrils or on the septum which di- 

 vides the one nasal cavity from the other and be easily detected, or they 

 may be higher in the nasal cavities on the turbinated bones, or they 

 may form in the larynx itself, or on the surface of the trachea or deep 

 in the lungs. 



The tubercles, which are first red and hard and consist of new con- 

 nective tissue, soon soften and become yellow; the yellow spot breaks 

 and we have a small ulcer the size of the preceding tubercle, which has 

 a gray, dirty bottom and ragged edges and is known as a chancre. This 

 ulcer pours from its surface a viscious, oily discharge similar to that 

 which we have seen in the farcy ulcer. The irritation of the discharge 

 may ulcerate the lining mucous membrane of the nose, causing serpen- 

 tine gutters with bottoms resembling those of the chancres themselves. 

 If the tubercles have formed in large numbers we may have them caus- 

 ing an acute inflammation of the Schneideriau membrane, with a ca- 

 tarrhal discharge which may mark the specific discharge, or that which
