Etiology .—The chicken cholera belongs, like the cholera of 
man (with which it is, however, not identical) to the miasmatic 
contagious diseases. It originates like them from Asia, and is 
produced and spread by a specific micrococcus. 
The animals become affected by taking up soiled food and im¬ 
pure water. The disease is most common among chickens, next 
frequent in geese and ducks, rare in turkeys, guinea hens, pigeons, 
pheasants and peacocks. 
Treatment .—Clean cooked food, clean acidulated drinking 
water, tannin, sulphate of iron, chlorine, permanganate of potash, 
carbolic acid, constant attention to cleanliness and ventilation of 
the chicken houses. Zundel recommends infusions of pine-tops. 
Sanitary Regulations .—Immediate separation of the healthy 
from the diseased, prevention of the importation of new chickens 
during the prevalence of the plague. Grouping of the fowl, 
cremation or deep burial of the dead, isolation of the diseased 
into separate sheds, which may be afterwards thoroughly disin¬ 
fected or burnt. 
For disinfecting purposes boiling water with mineral acids 
and chlorine are adequate. The exportation of chickens from in¬ 
fected places is to be prohibited. 
DISTOMA IN LIVERS AND LUNGS OF CATTLE, 
By Cooper Curtice, D.Y.S. 
I wish to record in your journal an additional instance of the 
presence of distoma hepaticum in the lungs and livers of cattle 
in this country. 
On the 4th of June last, while examining the viscera of cattle 
for intestinal parasites, three out of a herd of twelve from Kansas 
were found to be infected with flukes. 
Of these three I accept one case on the authority of Mr. 
Samuel Collins, the butcher who called my attention to them by 
describing the “ black, rotten liver ” he had found on the day 
before. 
The second case was affected in the liver only. The liver
