Diseases of the Respiratory Organs. 29- 



" In the left lung the anterior and middle lobes and 

 the lower free border of the posterior lobe are solidified. 



"In the right lung the lower three-fourths of the anterior 

 and middle lobes, and the lower fourth of the posterior lobe, 

 are in the same condition. Pleural surfaces involved. The 

 posterior half of the windpipe contains upon the mucous 

 membrane of its lower wall about a dozen small red patches, 

 which extend in the axis of the tube ; some appearing like 

 linear streaks due to the injection of a few vessels. In all 

 of them the presence of parasites can be determined, though 

 in some of the smaller only one is found. They become 

 more numerous about the bifurcation and in the main 

 bronchi, occupying chiefly the lower v/all. The masses are 

 isolated and the mucous membrane between them intensely 

 injected. None are found in the second divisions of the 

 tubes. 



" Abdominal organs contain a good deal of blood. Mucous 

 membrane of stomach and intestines looks healthy. The 

 large bowel contains a quantity of consistent faeces. Six 

 ascarides in the duodenum; six specimens of dochmius 

 trigonocephalus in the jejunum, and ten specimens of trico- 

 cephalus affinis in the caecum. 



" Blood of heart and veins examined ; nothing abnormal 

 found. 



« Case 5. — Seven months old bitch pup. Considerable 

 emaciation. Scattered areas of pneumonia throughout both 

 lungs ; not quite so extensive as in Case 4, but presenting 

 similar characters. . From an inch in front of the bifurcation 

 of the trachea to the bronchi of the second order, the whole 

 mucous membrane is transformed into an irregular greyish- 

 yellow granular structure, upon which the bodies of numerous 

 white worms can be plainly seen. Two sizes may be dis- 

 tinguished, one longer and of a more opaque white, which 

 subsequent examination showed to be the female, the other 

 shorter, thinner, and paler. In this case, even about the 

 orifices of the third division of the bronchi, a few nests of the
