Pagina 356 - Whilst formerly the greatest mental energies strove at universal knowledge, and that knowledge was confined to the few, now they are directed on specialities, and in these, again, even to the minutest points...
Pagina 204 - It was further shown that chemical decompositions may be produced by liquid diffusion ; the constituents of a double salt of so much stability as common alum being separated, and the sulphate of potash diffusing in the largest proportion. In fact the diffusive force is one of great energy, and quite as capable of breaking up compounds as the unequal volatility of their constituents.
Pagina 71 - ... at a high temperature, and recasting several times to give a great many tints, varying from blue to pink, red, opaque yellow, and green. Charcoal in excess in a mixture of silica-alkaline glass gives a yellow colour, which is not so bright as the yellow from silver, — and this yellow colour may be turned to a dark red by a second fire.
