PARASITES OF ANIMALS. ays, 
The bronchial Strongylus of Horses and Cattle. (Strongylus 
micrurus Mehlis.) See page 240, Report for 1870. 
During the past year a serious outbreak of the disease 
caused by this parasite occurred in Alleghany County, New 
York, which caused the death of many calves and the serious 
disease of all the cattle on the farm. Some of the worms 
were sent to me for examination, by Thomas L. Harison, Esq., 
secretary of the New York State Agricultural Society. They 
proved to be identical with this species, long known and 
dreaded by the farmers of Kurope. Professor James Law, 
who investigated this case, as well as two others of less im- 
portance which occurred previously, has published a full and 
interesting acount of them, in the Journal of the New York 
State Agricultural Society, for July and August, 1871, from 
which the following extracts have been made: 
‘‘ T have been able to find no proof of the existence of this 
disease among our sheep, and the only evidence of its exis- 
tence in calves is derived from the particulars of three out- 
breaks in different parts of New York, and about which I was 
consulted. 
The first of these took place in the autumn of 1869, among 
the calves of Mr. Wood, Woodville, N. Y., and though one 
or two had already died, the malady was easily controlled by 
putting in practice the measures advised in this paper. 
The second outbreak, which was only reported to me re- 
cently, occurred on the farm of Mr. Sutton, Ovid, Seneca 
county, N. Y. In this case four yearlings, fed during the 
previous autumn on a sloping dry orchard, and watered from 
a stream in a ravine close by, were attacked in March, 1870, 
while confined to the yards and fed on clover hay, with water 
from the stream. Two died in from six to ten days after the 
seizure, a third remained in low condition and perished in 
July, and the fourth recovered. On this same farnethe chick- 
ens and turkeys perished last summer in great numbers from 
the gapes, and squirrels have furnished specimens of bronchial
