26 THE MANAGEMENT AND DISEASES OF THE DOG. 



half-a-dozen, the size of marbles, closely set together in the 

 upper part of the posterior lobe. In the right lung the ante- 

 rior lobe is solid in an area 3" by 1", extending along the 

 lower free border, and through the whole thickness. Small 

 patches occur here and there over the other lobes. In this in- 

 stance the inflamed spots are smaller, and not so extensive as 

 in the other cases. On slitting up the trachea the mucous 

 membrane looks healthy to within 2" of the bifurcation, when 

 it becomes swollen, dark red in color, and thickly scattered 

 over with the elevated granular masses noticed in the first 

 case, attached to and in which numerous small white worms 

 can be seen. A stream of water of considerable force does 

 not wash them away, but shows that each little elevation con- 

 sists of a nest of the parasites. They extend to the tubes of 

 the second order, and are specially abundant at the bifurca- 

 tion itself, and about the orifices of the first tubes given off 

 from the main bronchi. The small tubes are filled up with a 

 frothy serum. Two of the worms are found far in the mucus. 



" Stomach and intestines appear healthy, except the lower 

 portion of the ileum, which is congested. 



" In this region ten specimens of dochmius trigonocephalus 

 occur, and 'further up in the bowel eight ascarides. 



" Case 4. — A six months old dog pup brought to the in- 

 firmary and died the next day. 



" 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 mem- 

 brane 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 numer-
