...number corresponded to the number of negatively charged electrons outside the nucleus. Element No. 1, hydrogen, has one such electron; No. 2, helium, has two; lithium, No. 3, three. . . . For each negative electron the nucleus of an atom must contain a positively charged proton. And, except in hydrogen, all nuclei were found to contain more protons than were electrons around them. The additional necessary electrons were found in the nucleus. Lithium, with three electrons outside the nucleus, must have a nucleus with a positive charge of three, and this positive charge may be made up in either of two ways...
Under the supervision of Dr. Stanley Cobb, Dr. F. Fremont Smith and Dr. Hans Zinsser of Harvard's Department of Neuropathology, Dr. Morrison killed five dogs suffering from running fits, made histological brain examination. He found the nuclei of the brain cells broken into bits, with chromatin scattered throughout the cell body. He discovered also great clusters of spider and mossy cells of the neuroglia around the small blood vessels in the white matter of the brain. In normal tissue, these supporting cells should be distributed in rows throughout the white matter. Cell peculiarities of the type found...
...Stoehr device, striker bars are so fixed to a piano's keys that when a key is touched a code impression is recorded on a motor-driven music-roll. Thus the most idle vagaries, nuclei for many a major opus, may be preserved. Added feature is a portable keyboard superimposed on the piano keyboard (baby grand or upright) which mechanically and instantaneously transposes music into any desired key. Composing and transposing devices may be used together. A great boon should "Music Writer" be to the cinema industry. Heretofore composition for synchronized cinema has been a labor of weeks. With...
Frederick Simonds Hammett, Philadelphia biochemist who has studied tissue growth for eleven years, decided after experiments on more than a million nuclei of tissue cells that a sulphur compound was directly responsible for tissue growth, that another sulphur compound was responsible for stagnation of tissue growth which comes with old age. His principle is universal, holds in the vegetable as well as in the animal kingdom...
Three other medical men were found for the nuclei around which Johns Hopkins was to grow great. One was a young Canadian, William Osier, destined to become Sir William, Regius Professor of Medicine at Oxford. Before going to Hopkins he had had ten years teaching' experience at McGill University, Montreal. For his work there he was later to get the unofficial title "Father of Modern Medicine in Canada." The other two nuclei: Dr. Howard Kelly, now an internationally known surgeon, and the late Dr. William Halsted, whose fame was his operative technique for the eradication of goitre...
