This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1847 Excerpt: ...without blackening; their aqueous solution precipitated nitrate of silver, and gave, with bichloride of platinum, a yellow precipitate; while the mother liquid, when mixed with alcohol, contained no traces of the double chloride of platinum and sodium. If the lighter fluid be poured off from the heavy viscid one, and the latter mixed with its own volume of ordinary ether, it becomes milky, and on standing a new separation takes place. On the bottom of the vessel there collects an amber-yellow viscid liquid, from which the supernatant lighter ethereal liquid can be easily separated by decantation. The heavier consists almost entirely of lactate of potash; the lighter contains also a certain quantity of that salt, but the chief ingredient of it is an organic base, which in properties and composition has been found to be identical with kreatinine. When the ether and alcohol are distilled off from this lighter fluid, and the residue evaporated to the consistence of a thin syrup, it forms, on cooling, a semi-solid mass of slender foliated crystals, which, by the addition of alcohol, may be separated from the mother liquid. When these crystals are washed with a little alcohol, dried, and dissolved in boiling alcohol, the solution deposits, on cooling, crystals possessing the form and properties of kreatine. At 212 they become opaque and dull, and lose twelve per cent, of water. The mother liquid, by gentle evaporation, yields yellowish four-sided tables. By means of a little blood-charcoal and hydrated oxide of lead, they are easily rendered colourless; their aqueous solution is strongly alkaline, and causes white crystalline precipitates in solutions of nitrate of silver, corrosive sublimate, and chloride of zinc. When mixed with hydrochloric acid and bichloride...
