Three years ago Professor Fred Allison of Alabama Polytechnic Institute was studying various elements by the magneto-optic method when he got unexpected results which led him to suspect the existence of a hydrogen isotope whose nucleus was twice as heavy as that of ordinary hydrogen. Not long afterward Dr. Urey and two associates concentrated enough of the isotope to identify it. He estimated that heavy hydrogen was present in ordinary hydrogen gas to the extent of about one part in 4,000. He named the new isotope deuterium...

...been talk of a third isotope of hydrogen whose atomic weight should be approximately 3 as against deuterium's 2 and hydrogen's 1. Two members of Dean Lewis's staff reported finding it last autumn (TIME, Nov. 20). But they used the same magneto-optic method by which Professor Allison predicted deuterium, and among scientists the worth of this procedure is debatable. In England Lord Rutherford (who calls deuterium diplogen and its nucleus the diplon) bounced deutons against deutons. Each collision produced a proton and something new of atomic weight 3. But cautious Lord Rutherford would...

...upon the removal of the goiter. When this does not happen, it is because the muscles sur- rounding the eyeballs remain swollen to from three to eight times their normal size Dr. Howard Christian Naffziger of San Francisco relieved the pressure by enlargement of the passages through which the optic nerves and the arteries of the eyes reach the eyesocket from the interior of the skull. The popping eyes then reset themselves...

Linton Perry knows that he is silly to do his trick. Dr. Smith explained to him that unless he ceases his monkey shines instanter, one of these days he will go blind. He will stretch his optic nerves so much that fibres will tear. Or he will jar loose the retinas in his eye balls...

Alger was second to none, although his supremacy was seriously questioned for a time by one Oliver Optic when he published "The Boat Club." His fame is somewhat different from the usual fame accorded great Harvard men. He was essentially a figure of the masses, a hero for the boys. It is today the opportunity of all Harvard men to give homage not only to its most widely read graduate, but to the institution which is so well equipped to render such manifold services to the world, an institution which has produced among others William Randolph Hearst, President Lowell...
