Diseases of the R^espiratory Organs. 23 



tion of a disease which had broken out among the pups at 

 the kennels ol the Montreal Hunt Club, and which was 

 believed to be of a pneumonic nature. On proceeding to 

 the place we found that the afifection 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 jn 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.' 



" I 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-
