Faraday to expose the hydrate of chlorine in a closed glass tube, it occurred to me that one of three things would happen: that decomposition of water would occur;... or that the chlorine would separate in a fluid state. Davy, moreover, immediately applied the method of self-compressing atmosphere to the liquefaction of muriatic gas.
It may also be made without putting in the water with the hydrate of lime, by merely passing the chlorine into the hydrate of lime. This last is by some used in preparations for accelerating the operation of taking Daguerreotypes, but when used for this purpose it is in small quantities. Chloride of Calcium.
The battery is kept up by adding every eight days a few thousandths of hydrochloric acid to a vatful of the spirits under treatment, say 5 kilos. of acid to 150 hectoliters of spirits. The object of adding this acid is to dissolve the hydrate of oxide of zinc formed during the electrolysis and deposited in a whitish stratum upon the surface of the copper.
In their application to the manufacture of batteries, the flakes are used through the medium of a special machine, so arranged that small charges of nickel hydrate and nickel flake are alternately fed into the pockets intended for positives, and tamped down with a pressure equal to about four tons per square inch.
Later on make a cotton tampon, saturated with chloral hydrate, one-half dram; cocaine hydrochloride, one and one-half grain; dissolve in five drams of water. Use injection and tampon morning and night. DYSMENORRHEA: Asafoetida, forty grains; ext. Valerian, twenty grains; ext. Cannabis Indica, five grains; make twenty pills. Dose: One pill after meals.
Again, the active materials of the electrodes being insoluble in, and absolutely unaffected by, the electrolyte, are not liable to any sort of chemical deterioration by action of the electrolyte no matter how long continued.... "The electrolyte of the Edison battery is a 21 per cent. solution of potassium hydrate having, in addition, a small amount of lithium hydrate.
The heat latent in that liquid, and necessary to keep it a liquid, is no longer necessary and comes out, and the substance appears to become hot. Quicklime is a cold, white, solid substance, but there is a compound of water and lime slaked lime which is also a solid powdery substance, called by the chemist, hydrate of lime.
She would become, for one thing, as sleepless as an owl; then she was thoroughly sure she was going to be insane, and down would go the hydrate of chloral till the doctor forbade it on pain of death. After the chloral, too, such horrid eyes as she had! the eyes, you know, that chloral always leaves inflamed, purple, swollen, heavy, crying, and good for any thing but seeing.
There was gunpowder of all varieties, antimony, blasting-powder, mercury cyanide, chloral hydrate, chlorate of potash, samples of various kinds of shot, some of the outlawed soft-nosed dumdum bullets, cartridges, shells, pieces of metal purposely left with jagged edges, platinum, aluminum, iron, steel a conglomerate mass of stuff that would have gladdened an anarchist.
If, therefore, a steam boiler is surrounded by a vessel containing a solution of hydrate of soda, having a high boiling point, and if the steam, after having done the work of propelling the pistons of an engine, is conducted with a reduced pressure and a reduced temperature into the solution, the latter, absorbing the steam, is diluted with simultaneous development of heat, which produces fresh steam in the boiler.
