140 GLANDERS AND FARCY. 



contained fluid, which is very similar to what we find in the 

 common and true glanderous growths, and in their disposition 

 again to fill when evacuated, and the slowness of the healing 

 process, these tumours or abscesses bear a greater resemblance 

 to ordinary cysts or abscesses than to the specific farcino- 

 glanderous sores. 



h. Diffuse Infiltrations. — The infiltrations or diffuse swell- 

 ings are the usual accompaniments of the pseudo-rheumatic 

 symptoms, and are chiefly located on the limbs in the vicinity 

 of joints. 



Unlike those already noted, they are not circumscribed or 

 defined so as to give a distinct and definite form to the enlarge- 

 ment ; but the infiltration is largely diflused, and gradually 

 shades off" until it meets or terminates in the normally condi- 

 tioned connective tissue. 



They differ also from those adventitious abscesses in their 

 want of permanence or stability, for one of their distinguish- 

 ing features is their metatastic character, in this simulating 

 the onset of rheumatic inflammations. 



They neither resemble the abscesses nor the true farcy 

 tumours, in as far as they rarely soften or suppurate, and that 

 when they do not remove by rapid change of situation, to 

 appear in connection with some other articulation, or are 

 apparently accessory to an outbreak of acute glanders, they 

 steadily become less by induration and removal of the more 

 fluid parts of the infiltration. 



Occasionally these conditions of specific infiltration have 

 been mistaken for and spoken of as farcinous invasion of the 

 constituent textures of the joint affected. Such in some 

 cases may be true, still in the entire number of those which I 

 have encountered there has been involvement chiefly of the 

 connective and fibrous tissues external and extraneous to the 

 joint proper. 



The pain and lameness on the first appearance of these infil- 

 tration swellings are well marked, the former gradually dis- 

 ajjpearing as the infiltration reaches its height, the latter con- 

 tinuing not exactly as lameness which it showed at first, but 

 as a peculiar stifthess seemingly from the mechanical impedi- 

 ment offered to the movements of the joint from the exuded 

 and infiltrated material.
