Diseases of the Respiratory Organs. 23 
tion o. a disease which had broken out among the pups at 
the kennels of the Montreal Hunt Club, and which was 
believed to be of a pneumonic nature. On proceeding to 
the place we found that the affection was confined almost 
exclusively to animals under eight months’ old, and that it 
had already proved fatal in several instances. At the time 
of the visit only one pup was ill, presenting symptoms of 
diminished air-space in the chest. In order to ascertain 
the exact condition of the lungs, one of the pups, which 
had died a day or two previously, and had’ meanwhile 
frozen stiff, was ordered to be sent to the Veterinary College 
for dissection. On the following day it was found at the 
autopsy that, in addition to the pneumonia, there were 
numerous small parasitic worms in the trachea and 
bronchial tubes. Knowing how subject many of the lower 
animals are to bronchial strongyles, I did not think it very 
remarkable that they should occur in the dog. On_ refer- 
ring, however, to Dr. Cobbold’s list of entozoa infesting the 
dog, I was surprised not to find a bronchial strongyle 
mentioned, and a further search through the standard 
works on veterinary medicine and helminthology proving 
fruitless, I then wrote to the editors of the Veterinarian 
asking for information on the subject. They very kindly 
replied in a short editorial) note in the March number, 
stating ‘that,’ so far as their knowledge extends, ‘no such 
cases have been placed formally on record, but Dr. Cob- 
bold tells them ‘that one such instance has been verbally 
brought under his notice, though not in such a way as to 
be thoroughly convincing.’ 
“T shall proceed now to speak of the symptoms and patho- 
logy of the disease, then give a description of the parasite 
itself, and make a few general remarks. 
“ Symptoms.—Only five of the diseased animals were seen 
during life, and that rather irregularly, on account of the dis- 
tance of the kennels from the city. However, I have ob-
