Page 73 - Soap-bark for forty-eight hours, with fifteen ounces of the Spirit, in a close vessel, agitating occasionally; then transfer to a percolator, and when the fluid ceases to pass, pour into the percolator the remaining five ounces of the Spirit. As soon as the percolation is completed, subject the contents of the percolator to pressure, filter the product, mix the two liquids, and add sufficient Proof Spirit to make one pint.
Page 88 - ... diluted hydrochloric acid, proceeding with caution, so that the morphia may be entirely dissolved, and a neutral solution obtained. Set aside to cool and crystallize. Drain the crystals, and dry them on filtering paper. By further evaporating the mother-liquor, and again cooling, additional crystals are obtained.
Page 15 - When mixed with an equal volume of pure sulphuric acid, and then introduced into solution of sulphate of iron, it does not communicate to it a dark colour.
Page 15 - Of the official solution of phosphoric acid it is stated that " 355 grains by weight poured upon 180 grains of oxide of lead in fine powder leave, by evaporation, a residue (principally phosphate of lead) which, after it has been heated to dull redness, weighs 215.5 grains.
Page 49 - Trans.,' 1861, 183) announces the following results : " If recently precipitated ferric hydrate or carbonate of ammonium is added to an aqueous solution of ferric chloride, as long as the precipitates are redissolved, and if the dark-red solution thus obtained, containing from 4 to 5 per cent, of solid matter, is subjected to dialysis, mainly...
Page 62 - Treated with a crystal of chlorate of potassium and a few drops of hydrochloric acid, and the mixture evaporated to dryness in a porcelain dish, a reddish residue results, which becomes purple when moistened with ammonia.
Page 96 - ELATERINUM.— ELATERIN.— The active principle of elaterium. It may be obtained by exhausting elaterium with chloroform, adding ether to the chloroformic solution, collecting the precipitate, washing the latter with ether, and purifying by recrystallisation from chloroform. Characters and Tests. — A chemically neutral substance. In small colourless crystals ; insoluble in water, sparingly soluble in rectified spirit. It has a bitter taste. Heated with access of air, it first melts and then burns,...
Page 84 - Shake this ethereal liquid with 6 cc of a 10% solution of sodium hydroxide, adding water if any solid matter should separate. Remove the ethereal solution, wash the aqueous solution with more ether, and remove the ethereal washings. Add diluted sulphuric acid to the aqueous liquid heated to boiling, until exactly neutral. When cold, collect any crystallised sulphate of cupreine on a tared filter; dry, and weigh.
Page 83 - Ten grains with ten minims of diluted sulphuric acid and half a fluid ounce of water form a perfect solution, from which ammonia throws down a white precipitate. This redissolves on agitating the whole with half a fluid ounce of...
Page 31 - A crystalline acid obtained by the combination of the elements of carbolic acid with those of carbonic acid gas and subsequent purification, or from natural salicylates such as the oils of wintergreen (Gaultheria procumbens, Linn.) and sweet birch (Betula lenta, Linn.).
