...always remain man, but he can change just as radically as the carbon, which is always carbon, may change from coal to a diamond, and in this process a free education is essential...
Professor L. J. Henderson '98, of the Chemistry Department will address the Chemical Colloquium, which meets this afternoon at 4.30 o'clock in Boylston 9. "Recent Progress in knowledge of the Movements of Oxygen and Carbon Dioxide Between the Air and the Cells of the Human Body" will be his subject...
...found that if 1 part of tetraethyl lead were added to 1,000 parts of gasoline, the effect was to retard the explosions- providing one slower detonation instead of two more rapid ones. This improvement prevents "knocking" in ordinary engines and, to a large degree, the deposit of carbon in cylinders. It laid open the possibility of building a new and more efficient type of engine to use the new mixture-a type of engine which, using ordinary gasoline, would soon pound itself to pieces. But lead is a poisonous substance. Tetraethyl lead must be handled with circumspection in production...
...evolved in the War, may solve the problem of feeding the world." The report of Dr. E. C. C. Baly contained a criticism. The butt was Nature-she takes too long to make sugar. He, the discoverer of synthetic sugar, has a receipt: Make a little formaldehyde out of carbon dioxide and water, expose it to intensely active ultraviolet light, and you have sugar. Genuine glucose has been made 'by this process, but before such can become a breakfast-table commodity the proper wavelength of the violet ray must be ascertained. It is roughly gauged at from...
...existence of the canals which Prof. Lowell so carefully mapped, an'd they point out that the light atmosphere, the extremes of heat and cold, the comparative absence of water (even if the polar caps consist of snow-and it is suggested that they may be congealed carbon dioxide-it is estimated that there is less water on Mars than there is in one of the larger of the Great Lakes) make life such as we know it impossible. But like the argument for "life," the argument against "life" is not conclusive...
