VERMINOUS DISEASE AMONG FOWLS.

the passage of the chyme, a quantity of which was found between 
this obstruction of the intestine and the gizzard. In the posterior 
part of the intestinal canal, almost at the anus, were ten other worms 
scattered here and there. The cloaca contained three. These worms 
were white, round, pointed at both extremities, and enlarged at 
one-third of their length. This enlargement contained a kind of 
receptacle for the intestines of these murderous guests. The 
worms were from two to three inches in length. The portion of 
intestine which contained them was engorged, and the mucous 
membrane ulcerated. 
There was nothing remarkable in the second fowl, =?xcept that, 
between two and three inches Irom the gizzard, the intestine con¬ 
tained twenty-three of these worms, and nine in other parts of the 
intestinal canal. 
The intestine of the third fowl contained thirty-two worms, three 
of which were in the cloaca. 
That of the fourth fowl contained twenty-eight. 
In the alimentary canal of the fifth were thirty-seven, including 
five in the cloaca. 
The worms in the last four were in the same division of the in¬ 
testines and convoluted in the same manner as in the first; and 
that portion of the intestine presented the same lesions. Neither 
the crop, the lungs, nor the abdominal viscera presented any thing 
remarkable. 
It was now evidently my duty to examine whether other poultry 
yards in the same locality presented a similar disease. 1 found 
that there were several fowls which exhibited symptoms very 
much like those which I have described. I purchased three of the 
worst of them, and, after having killed and plucked them, I pro¬ 
ceeded to a post-mortem examination of them. I found the same 
kind of worms, and in similar numbers, in their intestines. The 
crop and the thoracic and abdominal viscera presented nothing re¬ 
markable ; I therefore did not doubt that the disease and mortality 
of the birds were attributable to the presence of these parasites 
contained in the intestinal canal. 
Case II. — Madame Cousin, of Epinay-Champlatreux, had a 
yard w'ell filled with poultry of every kind, as is generally the case 
in large farms in that country. She lost every year a great many 
of her fowls, and particularly of the pullets and turkeys. This mor¬ 
tality became, at length, so fearful, that she began very rapidly 
to lessen her stock. In the f?pring of 1806, however, the pest 
seemed to have reached its greatest height, and she lost three or 
four pullets or turkeys every day. Alfrighted by this mortality, 
she determined to kill eveu’y fowl that (nxhibited the slightest trace 
of disease. This plentifully supplied her own table, and these half-
