or in kidney trouble, as in the last tlio swelling is cool and not painful 

 and tlie pitting ou pressure remains for some lime after the latter 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 withdrawn.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- swells for the en- 

 tire length in a single night, or within a very sliort period. When 

 greasy heels are complicated hy Ij'mphangitis we have a condition 

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

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

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

 and sensitive to the touch, but they have no tendency to suppuration. 

 The acute inflammation is rapidly followed by the specific induratloLi, 

 which corresponds to the local lesions in other i)arts of the body. 



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

 but sometimes occurs. 



ChroniG glanders. — In chronic glanders sve 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 divides the one nasal cavity 

 from the other and be easily detected, or they may be higher in the 

 nasal cavities ou the turbinated bones, or they ma3- 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 connect- 

 ive tissue, soon soften and become yellow; the yellow spots break and 

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

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

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

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

 may ulcerate the lining mucous n:embrane 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 causing 

 an acute inflammation of the Schneiderian membrane, with a catarrhal 

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

 from the ulcers and resembles the discharge of strangles or simple in- 

 flammatory diseases. 



The eruption of the ulcers and discharge soon cause an irritation of 

 the neighboring lymphatics; and in the intermaxillary space, deep inside 

 of the jaws, we find an enlargement of the glands, which for the first 

 few days may seem soft and cedematous, but which raiiidly becomes 

 confined to the glands, these being from the size of an almond to that of a 

 small bunch of berries, exceedingly hard ;iii(l nodulated. This enlarge- 

 ment of the glands is found high up oa the inside of tlie jaws, firmly
