Сторінка 724 - I often think it's comical How Nature always does contrive That every boy and every gal, That's born into the world alive, Is either a little Liberal, Or else a little Conservative!
Сторінка 7 - By Lord RAYLEIGH, FRS Received February 27, 1870. It has been known for many years that electricity has an extraordinary influence upon the behaviour of fine jets of water ascending in a nearly vertical direction. In its normal state a jet resolves itself into drops, which even before passing the summit, and still more after passing it, are scattered through a considerable width. When a feebly electrified body is brought into its...
Сторінка 506 - ... nor thermoelectricity plays an important part in the phenomenon. On the question of electrolysis, the following experiment, performed since the publication of Part I, has a bearing. Experiment showing Permanence of the Carborundum Rectifier. — In confirmation of the absence of electrolytic polarization, a durability test of the rectifier has later been made as follows : A crystal of carborundum enclosed in a glass tube with a few drops of oil...
Сторінка 736 - Effects due to variation in the clay. — Burned clays may be of many different colors. Although the majority of clays contain sufficient iron oxide to burn red, nevertheless it is not safe to predict, from the color of the...
Сторінка 504 - This preliminary test proved very interesting in that it showed that one may find, all over many of the pieces cut from a crystal of molybdenite, points where the substance is thermoelectrically positive and other points where it is thermoelectrically negative. These positive and negative points sometimes lie so near together that, with a fine-pointed exploring electrode attached to a galvanometer and warmed by heat conducted from the hand, one may find the deflections of the galvanometer reversed...
Сторінка 734 - Coloring action of iron in unburned clay. — Many clays show a yellow or brown coloration due to the presence of limonite, and a red coloration due to hematite; magnetite is rarely present in sufficient quantity to color the clay ; siderite or pyrite may color it gray, and it is probable that the green color of many clays is caused by the presence of silicate of iron.
Сторінка 7 - When a feebly electrified body is brought into its neighborhood, the jet undergoes a remarkable transformation, and appears to become coherent; but under more powerful electrical action, the scattering becomes even greater than at first. The second effect is readily attributed to the mutual repulsion of the electrified drops, but the action of electricity in producing apparent coherence has been a mystery hitherto.
Сторінка 322 - Mi, atomic metal analogous to vaporized metal in the case of metal overvoltages. 7. These products have been shown to be more reactive than the final products, and are sufficiently active to explain overvoltages found experimentally. 8. Active hydrogen has been shown capable of reducing cadmium from cadmium sulphate solutions, and reducing zinc from zinc oxide. 9. The theory put forward satisfactorily explains the known facts of overvoltage, a condition not satisfactorily met by previous theories....
Сторінка 8 - ... connected with a tap by india-rubber tubing. The pressure may be such as to cause the jet to rise 18 or 24 inches, or even more. A single passage of a rod of gutta-percha, or of sealing-wax, along the sleeve of the coat is sufficient to produce the effect. The seat of sensitiveness may be investigated by exciting the extreme tip only of a glass rod, which is then held in succession to the root of the jet and to the place of resolution into drops. An effect is observed in the latter but not in...
Сторінка 734 - Coloring action of iron oxide on burned clay. — All of the iron ores will in burning change to the red or ferric oxide, provided a sufficient supply of oxygen is able to enter the pores of the clay before it is vitrified; if vitrification occurs the iron oxide enters into the formation of silicates of complex composition. The color and depth of shade produced by the iron will, however, depend on...
