Page 3 - ... the second green substance is replaced by a third green substance, and the first yellow substance by a third yellow substance, to the presence of which the dull colour of those plants is due.
Page 278 - Chim. wed. 24, 258) likewise separates quinine and cinchonine by means of ether or cold alcohol, but first removes the greater part of the quinine by converting it into acetate (by precipitating with caustic soda and dissolving the precipitate in acetic acid) and crystallising out as far as possible. — Delondre & 0. Henry (NJ Pharm. 21, 281) triturate 10 grammes of the sulphate and 4 grammes of acetate of baryta with...
Page 143 - After washing away the hydrobromic acid, the contents of the tube are dissolved in 20 times their weight of warm alcohol of 80 pc, and the unchanged stearic acid is separated by cooling to — 10. The liquid is then mixed with an equal volume of water and an excess of crystallised carbonate of soda, and evaporated to dryness over the water-bath. The tough saline mass thus obtained is boiled with 10 volumes of alcohol of 80 pc, and filtered as hot as possible ; and the crystals of bromostearate...
Page 106 - One part of the salt forms, with 10 parts of cold water, an opaque gum, which melts at 99 and solidifies to a pearly gum on cooling. One part of the salt dissolves completely in 25 parts of boiling water, forming a liquid which is still limpid at 92, and solidifies to a pearly mass on cooling. The solution of 1 part of the salt in 100 parts of hot water deposits on cooling a mixture of mono- and bi-stearate of potash, while onefourth of the entire quantity of potash remains dissolved. When the...
Page 466 - ... separates a soluble neutral double salt, leaving behind an insoluble basic salt. Manganese-crenate is moderately soluble (Mulder). Aluminum-crenate is insoluble (Mulder). The insoluble salts .of both crenic and apocrenic acids are decomposed by and soluble in excess of solution of the alkaline salts. Silicic acid, precipitated from a liquid containing crenic acid, takes up a portion of the latter. Hermann finds two groups of acids, the crenic and oxycrenic acids, occurring in nature, viz : Humo-crenic...
Page 503 - It dissolves in strong nitric acid with flue green colour, which disappears on diluting the solution with water, but appears again when the liquid is concentrated, and is turned yellow by hydrosulphuric acid, protochloride of tin, and ferrous sulphate. Strong nitric acid also throws down from alcoholic strychnochromin, a green precipitate which loses its colour when washed. — Oil of vitriol turns strychnochromin green ; strong caustic potash decomposes it. — It is nearly insoluble in boiling...
Page 118 - Duffy's second modification is not obtained from pure stearin, which, however, contains the first and third modifications, even after several recrystallisations ; it is, therefore, not to be regarded as pure stearin (Heintz). — Tallow-stearin, melting- at...

After temporary oedema of the eyelids and conjunctiva on the right side, two breaches were found in the bone of the frontal region, through which the tumors appeared. Upon incision more than 90 vesicles, varying from the size of a pea to that of the fist of an adult, with easily recognizable buds and hooks, flowed through the opening and through the left nares. The case terminated in recovery. The...
Page 110 - Obtained by adding a solution of 20 grms. of .the sodium-salt in 6 or 6 oz. of strong alcohol to a solution of 12 to 13 grms. silvernitrate in an equal quantity of alcohol (Crowder). Amorphous white precipitate, very loose, and strongly electric when dry. Assumes a purple colour when exposed to light in the moist state ; not altered by light when dry. Insoluble in water, alcohol, and ether, easily soluble in aqueous ammonia.
Page 272 - They have a strong bitter taste, and frequently exhibit a pearly or silky lustre. They are precipitated by alkalis and their carbonates, by the hydrates of lime and magnesia, and by ammonia and carbonate of ammonia, hydrate of quinine being thrown down in white flocks. The precipitate produced by potash, ammonia, or carbonate of potash is pulverulent, and not crystalline nor soluble, to any great extent, even in excess of the precipitant ; the sulphate alone yields a precipitate easily soluble in...
