...small parish to another, teaching school besides preaching, and performing experiments of "natural philosophy" in makeshift laboratories. Extremely versatile, never idle, he learned all that his contemporaries knew about electricity and wrote a history of that mysterious force. By hit-or-miss methods he obtained in his retorts "marine acid air" (hydrochloric acid gas), "vitriolic acid air" (sulphur dioxide), "fluor acid air" (silicon fluoride), "alkaline air" (gaseous ammonia). One day, he tried passing electric sparks through his "alkaline air" and found that it decomposed into nitro gen and hydrogen. Then, "having a notion" that ammonia and hydrochloric acid gas, mixed...
...that life is an electric phenomenon. For nine years they studied living cells. They learned that every one of the 28,000,000,000,000 (28 trillion) cells in the human body are alike in that each is a tiny electric cell. The positive pole is an ultra-minute acidic nucleus held within an oily (lipoid) film.* The rest of the cell, the cytoplasm, is slightly alkalin in reaction. Consequently a minute electric potential is set up between the acid nucleus and alkalin cytoplasm. The electrical charge accumulates on the lipoid film, breaks through, and thereby establishes electric balance between...
...subject in its natural colors. Half Tones. The basis of half-tone printing as evolved by Mr. Ives lies in photographing the copy (subject) and transferring the negative to a copper or zinc plate treated with light-sensitive enamel; etching away the proper portions of the plate with acid; mounting the plate, inking and running it through a press. To produce a clear image (keep the ink from smearing) it is necessary to make the plate a mass of tiny points, whose size and proximity determine the value of the tone, the sharpness of the lines. This mass of points...
...Berlin, Professor S. Paldrock has succeeded in killing the bacilli and stopping the spread of local infection by freezing diseased tissues with carbonic acid snow. Of 16 patients treated, 7 have already been pronounced innocuous...
...jolting along in the peasant cart of one Tschaikovski, a Red guard, who later told her that he was a member of the firing squad but had subsequently covered her with a pile of rags, while the corpses of the murdered Romanoffs were dragged away to be destroyed by acid...
