DISEASES OF THE RESPIRATORY ORGANS. 27 



ous about the bifurcation and in the main bronchi, occupying 

 cliiefly the lower wall. 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 tricocephalus 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 distin- 

 guished, one longer and of a more opaque white, which sub- 

 sequent 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 parasite 

 can be seen. In the mucus from the smaller tubes a few of 

 the adult worms occur, and on spreading it out on glass slips, 

 and examining with a low power, a few ova and free embryos 

 are seen. 



" Blood of heart and veins contain no parasites. 



" Nothing abnormal in the stomach or intestines ; a large 

 specimen of taenia elliptica in the latter, also a few ascarides. 



" Case 6. — A thin, badly nourished dog pup, six months 

 old. Lungs present numerous patches of consolidation, invol- 

 ving on the right side the lower half of the anterior lobe, and 

 a large piece of the posterior lobe. On the left side the free
