may be the cause of sudden death in a dog. The following case, communicated by Professor Dick, illustrates this fact:
I lately had the body of a dog sent to me: his owner sent the following letter by the same conveyance.
"My keeper went out shooting yesterday morning with the dog which I now send to you. He was quite lively, and apparently well, during the former part of the day; but towards evening he was seized with violent vomiting. When he came home he refused to eat, and this morning about eight o'clock he died. As I have lost all my best dogs rather suddenly, I will thank you to have him examined, and the contents of his stomach analyzed; and have the kindness to inform me whether he has been poisoned, or what was the cause of his death."
On opening the abdomen, the viscera appeared quite healthy: the stomach was removed, and the contents were found to be more decidedly acid than usual. The acids were the muriatic and acetic: the finding of an increased quantity of these is far from being unusual. There was not a trace of arsenical, mercurial, nor any other metallic poison present. Of the vegetable poisons, I can only say there was not the slightest trace of the morbid effects of any of them. The pericardium and the left side of the thorax contained a small quantity of bloody serous fluid, and the heart was full of black blood. The left lung was a little inflamed. The trachea contained some frothy yellow mucous matter, similar to the contents of the stomach. In the larynx was found one of those worms occasionally inhabiting the cavities of the nose, and which had probably escaped from the nose while the dog had been hunting; and, lodging in the larynx, had destroyed the animal by producing spasms of the larynx. The worm was about one inch and a half in length, and had partly penetrated through the
rima glottidis.
Another worm about the same size was found in the left bronchia, and a still smaller one among the mucus of the trachea: there were also four others in the nose.
Some years ago I found some worms of the
