But the most formidable disease from which the young pheasant suffers is that known by the name of 'the gapes:'--so termed from the frequent gaping efforts of the bird to inhale a mouthful of air. Chickens and turkeys are equally liable to be affected by it; and it may be remarked, that a situation which has been used, for many successive seasons, as a nursery ground, is more apt to be visited with this plague, than one which has only recently been so employed. Indeed, I have observed that it seldom makes its appearance on a lawn or meadow during the first season of its occupation; and, therefore, when practicable, it is strongly to be recommended, that fresh ground should be applied to the purpose every year: and when this cannot be done, that a quantity of common salt should be sown broadcast over the surface of the earth, after the birds have left it in the autumn.

Dissection has proved that the latent cause of this malady is a minute worm of the genius _fasciola_, which is found adhering to the internal part of the windpipe, or trachea. Then Mr. Knox explains how this worm may be destroyed; (and only by such means,--the most delicate operator being unable to extract it without materially injuring the young bird)--viz. by fumigating with tobacco-smoke, according to the method (which he fully describes) recommended by Colonel Montagu. If the worm is not destroyed, the death of the bird ensues
