DINOSAURS DIED OF RICKETS
Thirty-five-ton dinosaurs, which languidly lived and loved in the slimy lagoons of the Mesozoic Age some 135,000,000 years ago, probably disappeared off the earth because their supply of ultra-violet light was cut off by vast clouds of volcanic dust obscuring the face of the sun. And so the biggest brutes that ever walked became extinct from the action of rickets, universally known today as a malady of babies.
AMATEUR COLOR MOVIES NOW POSSIBLE
Natural color movies that everyone can make and project had their scientific debut last Monday morning at the home of George Eastman, photographic pioneer and head of the Eastman Kodak Company at Rochester, N.Y.
Through the utilization of thousands of miniature lenses, invisible to the naked eye, but impressed into the photographic film itself, these new colored motion pictures will come into the American parlor before they are shown in magnificent movie palaces.
By slipping a special color filter into the ordinary amateur movie camera and using the special film, the amateur can take the new color motion pictures. In development the film is changed to a positive but due to the principle of the process the film is just black and white, with no color or dyes appearing in the film itself.
BLOOD MYSTERY SOLVED
Using a specially devised instrument, Drs. W.F. Hamilton, J.W. Moore, J.M. Kinsman, and R.G. Spurling of the University of Louisville School of Medicine have solved a 300-year-old puzzle of medicine and physiology, when they determined by experiments just completed that the heart pumps blood at the rate of 5.2. liters, or about 5 1/2 quarts, per minute.
