DISEASES OF THE RESPIRATORY ORGANS. 21 



Veterinary College for dissection. On the following day it 

 was found at the autopsy that, in addition to the pneumonia, 

 there were nurnerous 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 re- 

 ferring, 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 helrainthology proving fruitless, 

 I then wrote to the editors of the Veterinarian asking for in-

 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. Cobbold tells them ' that 

 one such instance has been verbally brought under his no-

 during life .and that rather irregularly, on account of the dis- 

 tance of the kennels fronl the city. However, I have ob- 

 tained some important details from the keeper, and a case 

 which was brought to the infirmary and kept for some time 

 was made the subject of clinical study. 



" Among the initial symptoms disinclination for food and 

 exercise, together with an unsteadiness of gait, amounting in 

 some of the cases to a subparalytic condition of the hinder 

 extremities, were the most evident. In fully half of the cases 

 convulsions occurred. There was rarely diarrhoea or any 

 Other symptom referable togastro-intestinal disorder. Cough 

 was not a prominent symptom, being absent in many of the 

 cases. When present, it was short and husky, 'not,' as the 

 keeper said, ' the regular distemper cough.' In the case
