rang'eiuent of the secretions is noticeable. There is no fuN-er, and the circn- 

 Jation at first is normal, becoming -weaker and more rapid toward the last. 

 Several i)ost-moricr,i examinations of cattle dying of this disease wcvi- 

 made, but withont satisfactory results, as each case seemed to preR<3ut 

 dilierent features. 



The report of this committee Avas submitted to li. McClure, ve- 

 terinary surgeon of Philadelphia, who replios that the disease as 

 described is clearly parasitic (cntozoa) in its character, and is due to 

 jiicking up from the pasture the tiny ova of one or other of the many 

 parasites inhabiting the " unclean hog," as the cysticercus fccnia solium 

 and scrratitm, the iricMna qnralis, &c. When the ova of the cysticerciis 

 of tlie hog is swallowed by young persons and young animals measles 

 (ruhcolaj is the result in one, and a disease of the brain in sheep and 

 cattle in the other. The disease, then, is the result of swallowing the 

 ora, or eggs, of parasites ejected from the hog, giving rise to constitu- 

 tional irritation, followed by effusions of lymph fluid, or serum into the 

 subcutaneous tissue, and hence the extreme itching, in these cases ex- 

 hibiting efiusion (water) on the brain or a.t the base of the horn, is merely 

 the partial develo]>ment of hydatids hydroeeplialus^ sturdy, &.Q.. 



DISEASES OF SHEEP. 



FooT-iiOT. — In Orange County, A'ermout, foot-rut has pre^^aiied to a 

 slight extent, but increased care and cleanliness have greatly limited its 

 range. lu Berkshire County, Massachusetts, two years ago, it infected 

 nearly everj' ilock,but, by culling out diseased animals and by increased 

 care, foot-rot is seldom heard of. in New York it is reported to a slight 

 extent, in Oneida and Onondaga Counties, and in a mild form in Onta- 

 rio, in Columbia its virulence is declining, and it generally yields to an 

 application of v;hite vitriol. In Yates County, however, it was very 

 destru(!tive, alfecting 75 per cent, of the flocks. In New Jersey foot-rot 

 is reported in Hunterdon, Salem, Burlington, and Ocean Counties. In 

 the last-named county the disease yields readily to a weak solution of 

 corrosive sublimate. 



In Pennsylvania the disease is reported from Mercer, Warren, Wash- 

 ington, McKeau, Lycoming, and Westmoreland Counties, but no in- 

 crease of intensity is marked, in Washington County it is confined 

 to merinoes. In Warren County it was successfully treated by clean- 

 ing and paring th6 hoof and applying strong muriatic acid. In Kent 

 County, Maryland, the foot-rot has been bat slightly ju'evalent. In 

 Lawrence County, Alabama, foot-rot is mentioned. In Galveston 

 County, Texas, the losses from feot-rot amounted to 10 per cent. In 

 Brooke County, West Virginia, about 12 per cent, of the flocks have 

 been afiected with foot-rot. In Hancock County 15 per cent, of the 

 flocks have been affected, but the disease is not nearly so prevalent as 

 in former years. In Logan County, Ohio, but 1 per cent, of the sheep 

 were affected, the disease having been almost exterminated by the 

 slaughter, for pelts and tallow, of the unhealth.\'* animals. In one case 

 five thousand sheep were disposed of, the purchaser returning to the 

 seller the pelts and 5 cents per head. In Medina County, however, 

 half the sheep are affected with foot-rot. In ivosciusko County, Indi- 

 ana, foot-rot affected about 5 jier cent, of the sheep, being confined 

 mostly to a few large flocks of merinoes. in Wayne County a few cases 

 of foot-rot were reported, vrhich, it was thought, would be cured by a 

 change of pastures. In ]\rartin County the merinoes lost 20 jier cent. 

 In Lenawee County, Michigan, a few cases were reported, but confined
