different products are virulent and the circumstances in which ex¬ 
posed animals are susceptible. The proper supervision of this af¬ 
fection will demand the most careful consideration of' the sound¬ 
est and most enlightened minds. It would demand—first, the 
enforcement of a series of sanitary rules for the construction and 
management of city and suburban cow-stables, embracing the 
sites, exposure, drainage, space per animal, ventilation, water 
supply, food, cleanliness, &c.; second, a professional inspection of 
the cow stables to insure that no cow with active tuberculosis is 
kept for the supply of milk, and no bull for the propagation of 
his kind; third, a professional inspection of the slaughter-houses 
and poulterers’ to see that no flesh or other products from danger¬ 
ously tuberculous animals are allowed to pass into consumption 
as human food. As far as possible a sanitary control should be 
established over country herds as well, and means should be taken 
to extirpate the disease and remove its causes in the many dis¬ 
tricts in which the affection has become domiciled as an enzootic. 
MALIGNANT (ASIASIC) CHOLERA. 
With the threatened approach of a new visitation of cholera 
the National Board of Health must apply to the lower animals all 
those precautions which have proved beneficial in warding off this 
scourge from the human race. In this connection it need only be 
stated that Annesley, Jamieson, and many other Indian physi¬ 
cians testify that during cholera epidemics the domestic quadru¬ 
peds often showed a greater mortality than man, and that poultry 
yards were utterly depopulated by the scourge; that Hildebrandt, 
Hering, Hick, Reynal, and others record the ravages of this 
plague simultaneously in man and animals in Europe; and that 
Burden Sanderson and others have produced the disease experi¬ 
mentally in the rodents by feeding paper dipped in the virulent 
alvine discharges of men. It has often been noticed that birds 
disappeared during the cholera epidemics, the rational explana¬ 
tion being that they perish. This will especially demand the 
careful seclusion of all animals in cholera districts; the destruc¬ 
tion, if necessary, of wild animals; the disinfection of all bowel 
dejections and of the carcasses of animals dying of the plague, as
