... something wild in his aspect that must needs attract the attention of the passers-by. At each step he half expected the leveling of some accusing finger. The pitiless sunshine seemed to single him out and stream upon him like a calcium light. It was intolerable. He must get away from this jostling crowd, this babel of voices. What should he do, where should he go? To return to the yard and face the workmen was not to be thought of; if he went to his lodgings he would be called ...

... even the propulsive power been developed. Inventors had to wait till science had given us in abundance a metal less than a quarter the weight of iron, but as strong and durable, and this was not until some fifty years ago when a process was discovered for producing cheaply the beautiful metal calcium. But calcium would have been little use alone. Aluminium, which is now so plentiful, had to be alloyed with it, and aluminium was not used to any great extent till the beginning of this century, ...

... mix it with water, generates great heat; and this is due to its attraction for the water. Sometimes two fluids unite together, and, in doing so, pass from the liquid into the solid form; as, e.g., sulphuric acid and chloride of calcium.

Those who have seen these damsels in their glory, in the full glare of the foot and calcium lights, amidst the most gorgeous surroundings, and under the influence of delicious music, may have come to the conclusion that such a life must be very pleasant. They little know the experience of a ballet girl. "It's a hard life," said ...

A compound is made of calcium and carbon, called calcium-carbide, which, in touch with water, produces the acetylene gas. Its lighting power is fifteen times that of the ordinary illuminating gas, ...

The Rodin case puts a by no means seldom-recurring phenomenon in the centre of the stage under a calcium light.

... combination of persulphomolybdic acid with a base are pulverulent, in many cases of a red colour, and for the most part insoluble in water. With barium, the acid furnishes a yellowish-red powder, insoluble in, but made denser by water, which imparts to it a cinnabar colour. With calcium it is said to yield a scarlet, sparingly soluble in water. With chromium, uranium, lead, platinum, and copper, it gives a dark red; that from the last metal turning brown when collected on a filter. It likewise ...

... by a second baking, but attempts in this direction were not uniformly successful, it being found that the dehydrated substance in some cases refused to set with water. It behaved in fact similarly to the natural anhydrous calcium sulphate which is unaffected by water. These failures were found to be due to the employment of too high a temperature, and such plaster was termed dead burnt. Although this fact was ascertained long ago, yet ignorance of what had already been done has probably been the ...

Parinacochas water contains more carbonate and potassium than that of ...

... soaps at the strengths tested, except that fish-oil soap, 5 to 50, killed 90 per cent of the aphides. Laundry soap, 3 to 50, was effective against the young aphides only. Arsenate of lead alone, as was to be expected, had little or no effect upon the aphides. The combination of arsenate of calcium with kerosene emulsions is not a desirable one, since an insoluble calcium soap is formed, thereby releasing some free kerosene.—U.S. ...

This was the first cavern of any size that I had ever visited and I was so taken up with examining the rock formations and keeping my torch ...

You will have gums and resins from the wood, calcium chloride from the bleach vats, acids from the "sours"; resin, and resin-soaps; there may also be alumina salts present. Now alumina, lime, resin, and resin-soaps, etc., precipitate dyestuffs, and also soap; if the water is alkaline, ...
