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 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 j jejunum, and ten specimens of trico- 
cephalus affinis in the cecum. ~ 
“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 ofnumerous 
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
