ADDITIOXAL LESIONS AND TEXTURAL CHANGES. 139 



cent lymphatic glands. This condition is much similar to 

 what has been mentioned as existing in acute farcy, only the 

 surrounding and interconnective cellular tissue of the glands 

 is here less swollen as the infiltration seems less ; the indura- 

 tion and nodulation, or superficial irregularity, is, however, 

 equally well marked, but the tenderness on manipulation is 

 not so attractive. Generally at the commencement of the 

 swelling the infiltration of the surrounding and interlacing 

 tissue is most distinctive, gradually decreasing to a certain 

 point, and in this way allowing the indurated and nodulated 

 condition of the gland to be observed and felt. Although 

 this enlargement and induration may continue for a lengthened 

 period, softening and suppuration are here even more rare than 

 in either glanders proper or the acute form of farcy. 



Additional Lesions and Textural Changes.— These peculiar 

 conditions of irregularly developed neoplastic formations, 

 their growth and further disintegrative changes, together 

 with the specific inflammation of the lymphatic vessels 

 and lymphatic glands, although constituting the great diag- 

 nostic features of chronic farcy, are, like the similar mani- 

 festations of the specific poison in nearly all the other forms 

 of equina, occasionally and in particular cases added to by the 

 occurrence of phenomena which, if not specially diagnostic, 

 are at least peculiar in their association with the different 

 developments of this general infective process in the horse. 



These phenomena and manifestations of morbid activity are 

 the occurrence in different parts of the body of {a) circum- 

 scribed tumours or abscesses, and (b) of diffuse infiltrations. 



a. Circumscribed Tumours or Abscesses. — These are per- 

 fectly distinct from the tumours or nodules diagnostic of the 

 disease, and must not be confounded with them. They are, 

 when occurring, generally situated on the more exposed parts 

 of the body, the scapular region, the sides, and haunches. 

 They are evidently inflammatory in character, of much larger 

 size than the ordinarily encountered adventitious growths of 

 farcy; they are tolerably well defined, and, unlike the true 

 farcy tumours, are not disposed to take on the ulcerative pro- 

 cess. Neither at their base nor around their border is there 

 the characteristic infiltration and induration of the nodules. 

 In all their characters, with the exception, probably, of the
