AUTOPSY 133 



mucous membranes in the cisterns may show small, red, 

 pointed growths (condyloma). In the common complica- 

 tion of gangrene a stinking odor is present. 



Tuberculosis. — The affected quarter is usually hard 

 and severely swollen. 



The corresponding lymph-gland is increased in size. 

 The incision in the lymph-gland is either succulent, as in 

 udder-tuberculosis, or more or less dry and often gritty, as 

 in advanced udder-tuberculosis. The juicy cut surface is 

 spongy in consistency and shows few, if any, small caseous 

 foci. The dry cut surface is caseous for the most part and 

 therefore yellow in color. The consistency is firm and in 

 calcification very firm. 



The incision in the udder is comparatively dry and in 

 advanced tuberculosis gritty, due to calcification. The 

 affected inferior portion of the cut surface is even, the con- 

 sistency is firm and the color grayish-yellow. The superior 

 portion of the cut surface bulges or is convex. It shows 

 a number of yellowish-gray, round, protruding nodules, 

 varying in size from a poppy seed to a hemp seed, or small 

 wart-like structures situated here and there in the lobuli. 

 The lobuli present no milk points, but small yellowish- white 

 caseous points instead. Usually, but not invariably, yellow 

 caseous masses may be expressed by pressure upon the 

 lobuli. In addition, if the condition is old, one may see 

 yellow, round, sharply circumscribed necrotic foci of vari- 

 able size ranging from a hemp seed to a walnut or larger. 

 The necrotic parts are loose and thickly fluid or firmly 

 caseous. It can be calcareous and the calcification begins 

 in the centre and is manifested by a brighter point or nucleus 

 which later enlarges. The necrotic area is usually sur- 

 rounded by very thin connective tissue. In the superior 

 convex part of the cut surface the color is whitish-gray. 

 The consistency is very soft and elastic. The lobuli are
