At a recent meeting of the Franklin Institute of Philadelphia, Baugh & Sons presented the Institute with samples of products from animal bones made at the Delaware River Chemical Works. They stated that Philadelphia produced daily from 80,000 to 100,000 pounds of bones, all of which, by the art of the chemist, are converted into useful materials. Bone oils, ammoniacal liquor, bone black, carbonate, sulphate, nitrate and muriate of ammonia, fertilizers and sizing glues are among the products, samples of which were exhibited.
