Side iii - A manual of the general principles of the science, and their applications in medicine and pharmacy.
Side 146 - The liquid is poured out on a clean smooth slab, broken up and preserved in a glass-stoppered bottle. Solid iodide of iron has a crystalline fracture, is " green with a tinge of brown ; inodorous, deliquescent, and almost entirely soluble in water, forming a slightly green solution which gradually deposits a colored sediment and acquires a red color.
Side 521 - Weight. — The Unit of Weight is the GRAM, which is the Weight of that quantity of distilled water, at its maximum density, which fills a Cube of the One-hundredth part of the Metre. TABLE. Note. — Multiples are denoted by the Greek words " Deka," " Ten," " Hecto," Hundred, " Kilo,
Side 355 - Let this stand in a well-closed vessel for twenty-four hours ; then, having quickly enveloped it in a linen cloth, submit it to strong pressure in a suitable press, so as to separate the liquid portion. Reduce the pressed cake to powder, mix it with sufficient ether, to which one-sixteenth of its bulk of water has been added, to form again a soft paste, and press this as before. Mix the expressed liquids, and expose the mixture to spontaneous evaporation until, by the aid subsequently of a little...
Side 607 - Transfer it to a displacementapparatus, and pour on the remainder of the water in successive portions, so as to exhaust the opium by percolation. To the infusion thus obtained, placed in a flask, add the lime, boil for ten minutes, place the undissolved matter on a filter, and wash it with an ounce of boiling water. Acidulate the filtered fluid slightly with diluted hydrochloric acid, evaporate it to the bulk of half an ounce, and let it cool.
Side 107 - Distilled water, 1 pint. Mix the lime and sugar by trituration in a mortar. Transfer the mixture to a bottle containing the water, and, having closed this with a cork, shake it occasionally for a few hours. Finally separate the clear solution with a siphon and keep it in a stoppered bottle.
Side ii - But the greatest error of all is, mistaking the ultimate end of knowledge; for some men covet knowledge out of a natural curiosity and inquisitive temper; some to entertain the mind with variety and delight; some for ornament and reputation; some for victory and contention; many for lucre and a livelihood ; and but few for employing the Divine gift of reason to the use and benefit of mankind.
Side 428 - For this purpose use a tube furnished with a stopcock to regulate the supply, connecting one end of the tube with a vessel containing the spirit raised above the level of the matrass, and passing the other end through a cork fitted into the matrass.
Side iv - In the following particulars : first, in the exclusion of matter relating to compounds which, at present, are only of interest to the scientific chemist ; secondly, in containing the chemistry of every substance recognized officially or In general, as a remedial agent. It will be found a Biot>t valuable book for pupils, assistants, and others engaged in medicine and pharmacy, and we heartily commend it to our readers.
