THE MILK TRADE or NEW YORK—By John Mul Ialy : Fowlers & Wells, pp. 118.; price 25 cts. An excellent little treatise on the Milk Trade of New York, an article that forms so important an item in the food of mankind. The author gives some useful statistics, and shows the injurious effects of UBing what is commonly called “swill milk,“ which, as is well known, is obtained from cows stabled in the city and fed on the refuse from brew-houses and distilleries. An exposure of this system of supply so deleterious to the healtli of our citizens was very much wanted, and we hope that this pamphlet will be read by every one.
