THE NEWEST LOCOMOTIVE

The cover illustration this week is of the replica of the famous English locomotive, the "Rocket," which has been made for the Ford Museum at Dearborn, Mich.

HOG STOMACH NEW ANEMIA REMEDY

Dried stomachs of hogs are soon to vie with livers as the saviors of sufferers from pernicious anemia. This newest anemia remedy, made from one of the few unused parts of hogs, has just been developed and announced by Drs. Cyrus C. Sturgis and Raphael Isaacs of the Simpson Memorial Institute for Medical Research of the University of Michigan and Dr. Elwood A. Sharp of the Department of Experimental Medicine of Park, Davis and Co.

An ounce of extract from the dried, ground stomachs of hogs is as effective a remedy in pernicious anemia as a pound of raw liver or three ounces of the most concentrated liver extract ever made.

PLANT COLOR RELATED TO BLOOD

Another step in the solution of two fundamental problems of plant and animal life has been taken by Prof. Kurt Noack of Bavaria, who has just shown that chlorophyll, the green coloring of plants, is related to blood and is derived from a substance known to biochemists as protochlorophyll.

Chlorophyll is the most abundantly produced complex organic chemical compound on the Earth upon which we live, said Dr. Frank M. Schertz of the U.S. Bureau of Chemistry and Soils in explaining Prof. Noack’s discoveries.

63-STORY BUILDING MOST ECONOMICAL

On a piece of city realty, with the land worth $200 per square foot, a 63-story building will yield the greatest return on the investment. With the land worth $400 a square foot, which is more nearly the value of land in the Grand Central Terminal region of New York, a 75-story building will pay best. The engineering difficulties of a building as high as 2,000 feet, or nearly 200 stories, could be overcome, but such a structure would not be economically feasible. Even a building of 131 stories would not return any net income.

These are some of the principle conclusions drawn from a study that has been in progress during the last two years, under the direction of W.C. Clark, New York economist, for the American Institute of Steel Construction.
