and mesenteric lymph glands; and in great numbers in the con- 

 nective tissue along the back, especially in the neighborhood of 

 the kidneys. In 2 cases, the connective tissue along the spinal 

 column extending from the coccyx to the diaphragm was a mass 

 of worm tracts, most of which contained one or two worms and 

 purulent material. In 3 cases, worms were found free in the 

 thoracic cavity and embedded in the pleura. One worm was pene- 

 trating the lung tissue. Some were embedded in the diaphragm. 

 Thus it will be seen that, when an animal dies of kidney-worm 

 infestation, the disease presents a generalized instead of a 

 localized aspect. 



Several writers state that the worm is never found in the in- 

 ternal structure of the kidney. This may be true in those cases 

 noticed in the abattoirs where the infestation is not of long 

 standing, but if one examines animals which have died of the 

 disease he will find the kidney structure to be invaded in a 

 majority of cases. 



MORBID ANATOMY 



One of the most prominent changes to be noted at autopsy is 

 the rapidity with which the internal organs undergo post-mortem 

 changes. Four of the 6 animals were examined shortly after 

 death. The viscera of these animals had a disagreeable odor as 

 if decomposition was well advanced. Changes in the various 

 organs were observed as described below. 



LIVER 



In every case, the liver was enlarged, soft, and of a dark 

 purplish color. The borders of the lobes instead of tapering 

 down to a rather thin edge were distended and rounded. In 

 some instances, collections of gas bubbles were noticed under 

 the capsule, suggesting that putrefaction was taking place 

 rapidly. The dependent portions of the lobes of the liver were 

 of a uniform dark purplish color, and the individual lobules were 

 not distinguishable through the capsule. The upper portion of 

 the lobes had a mottled appearance. The majority of the lobules 

 in some cases were dark purple, while the remaining lobules varied 

 from a purplish tint to gray-brown. Upon section, the paren- 

 chymatous tissue was soft and bulged out on the incised surface, 

 and the borders of the lobules were indistinguishable. The lobes 

 adhered to each other by a gray, feltlike fibrinous exudate. 

 This was especially prominent in the dependent portions. In 3 

 cases, the liver was adherent to the diaphragm, sternum, and 

 stomach.
