blood-tinged serum escaped, but no trace of any parasites 
can be found either in the tubes or parenchyma of the lungs. 
No ova or young parasites can be found in the blood of the 
cavities of the heart or of the pulmonary artery. 
“ Abdominal viscera appear healthy, though, owing to the 
obstruction in the lesser circulation, the blood-vessels are 
engorged. A few ascarides in the intestine and one small 
tenia elliptica. 
“CASE 3.—Dog pup, six months old. 
“In the left lung there are scattered patches of pneumonia 
in the anterior lobe, one or two are in the middle lobe, and 
half a dozen, the size of marbles, closely set together in the 
upper part of posterior lobe. Inthe right lung the anterior 
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 instance 
the inflamed spots are smaller, and not so extensive as in the 
other cases. On slitting up the trachea the mucous mem- 
brane looks healthy to within 2’' of the bifurcation, when it 
becomes swollen, dark red in colour, 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 
consists ofa nest ofthe parasites. They extend to the tubes 
of the second order, and are specially abundant at the 
bifurcation itself, and about the orifices of the first tubes 
given off from the main bronchi. The small tubes are filled 
up witha 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 dochmiustrigonocephalus 
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.
