Page 217 - ... parts of dry alumina added to it, and the whole evaporated together, being continually stirred until it becomes a damp powder. This combination of silica, alumina, and soda, is the basis of ultramarine, and is now to be coloured by a sulphuret of .sodium in the following manner. A mixture of two parts of sulphur with one part of an hydrous carbonate of soda is to be put into a Hessian crucible, covered up, and then gradually raised to a red heat until it is well fused; then the mixture is to...
Page 251 - Methought I heard a voice cry, Sleep no more ! Macbeth does murder sleep, the innocent sleep ; Sleep, that knits up the ravell'd sleave of care, The death of each day's life, sore labour's bath, Balm of hurt minds, great nature's second course, Chief nourisher in life's feast ;— Lady M.

Page 451 - ... few but the poisonous. The safe kinds have most frequently a compact brittle texture; the flesh is white ; they grow more readily in open places, such as dry pastures and waste lands, than in places humid or shaded by wood. In general, those should be suspected which grow in caverns and subterraneous passages, on animal matter undergoing putrefaction, as well as those whose, flesh is soft or watery.—Quarterly Journal of Science.

Page 99 - The want of wholesome air, however, does not manifest itself on the system so unequivocally, or imperatively; no urgent sensation being produced, like that of hunger, and hence the greater danger of mistaking its indications. The effects of its absence are only slowly and insidiously produced; and thus, too frequently, are overlooked until the constitution is generally impaired, and the body equally enfeebled.
Page 82 - Sydenham, sir, said the arrival of a merryandrew in a town was more beneficial to the health of the inhabitants than twenty asses loaded with medicine.
Page 205 - ... ferrous sulphate has time to oxidate in the air. The two portions of diniodide of copper obtained as above, are next dried at a gentle heat (a stronger heat would decompose the diniodide of copper — since it is mixed with disulphate of ferric oxide — and evolve iodine); the whole mixed with twice or three times its weight of peroxide of manganese, and a sufficient quantity of oil of vitriol to form it into a paste ; and the mixture strongly heated in a subliming apparatus : Cu'I + 2MnO> +...
Page 217 - Pulverized quartz is to be fused with four times its weight of carbonate of soda, the mass dissolved in water, and then precipitated by muriatic acid; thus a hydrate of silica will be formed. A hydrate of alumina is to be prepared by precipitating alum by ammonia. These two earths are to be carefully washed with boiling water ; the proportion of dry earth in each of them is to be ascertained by heating a small quantity and weighing it.
