Wolcott's American Mixture.--Van Loan Quick.--This mixture was first formed and used by T. Wolcott & Johnson and gained great celebrity for its productions. I have now a bottle hermetically sealed that contains about a half ounce of this mixture prepared in 1841 by John Johnson, now a resident of this city, and the former partner of Mr. Wolcott. The preparation of this mixture, as furnished by Mr. Johnson himself, is given as follows:英文原著 · 《American Hand Book of the Daguerreotype》
[Footnote d: A strange sophism has been made on this head in France. When a suit arises between the government and a private person, it is not to be tried before an ordinary judge - in order, they say, not to mix the administrative and the judicial powers; as if it were not to mix those powers, and to mix them in the most dangerous and oppressive manner, to invest the government with the office of judging and administering at the same time.]英文原著 · 《Democracy In America-2》
Fire-damp, marsh-gas, or carburetted hydrogen, is colorless, almost scentless; it burns with a blue flame, and makes respiration impossible. The miner could not live in a place filled with this injurious gas, any more than one could live in a gasometer full of common gas. Moreover, fire-damp, as well as the latter, a mixture of inflammable gases, forms a detonating mixture as soon as the air unites with it in a proportion of eight, and perhaps even five to the hundred. When this mixture is lighted by any cause, there is an explosion, almost always followed by a frightful catastrophe.英文原著 · 《The Underground City》
"The objections to mixed classes proved to be idle words; yet the old-fashioned minds opposed to us shut their eyes and went on reasoning _'a priori,_ and proving that the evils which they saw did not arise _must_ arise should the experiment of mixed classes, which was then succeeding, ever he tried.英文原著 · 《A Woman-Hater》
Iodide of Lime is prepared by adding iodine to hydrate of lime (which will be referred to farther on) until the mixture assumes a light yellow shade, when wanted for combinations with accelerators, or to a dark brown when employed for the first coating. This latter mixture has been sold in our market under the name of "Iodide of Brome."英文原著 · 《American Hand Book of the Daguerreotype》
"Use.--A few drops say, 6 to 12, of this mixture, should be put into about 6 or 8 ounces of water; it will require frequent replenishing by the addition of a few more drops. The plate should be coated over the dry iodine to a red just bordering on a slate. and then exposed to the mixture only sufficiently long to change the color. If this is not done in less than six seconds it is not strong enough. Re-coat over the iodine full one fourth as long as first coating."英文原著 · 《American Hand Book of the Daguerreotype》
