A writing thirty years old gives, by this method, a copy hardly legible, and one over sixty years old, a copy hardly visible. In order to protect the paper against the action of the acid, it should be drawn through ammoniacal water. To determine the exact age of writings by the ink is not easy. The approximate age may be determined with some degree of certainty.
Everywhere there were visions of glossy brown backs, straining, heaving, swollen with muscle; harness streaked with specks of froth, broad, cup-shaped hoofs, heavy with brown loam, men's faces red with tan, blue overalls spotted with axle-grease; muscled hands, the knuckles whitened in their grip on the reins, and through it all the ammoniacal smell of the horses, the bitter reek of perspiration of beasts and men, the aroma of warm leather, the scent of dead stubble and stronger and more penetrating than everything else, the heavy, enervating odour of the upturned, living earth.
The warehouses are of all types, from dusty lofts over stores, and ammoniacal lofts over stables, to buildings offering acres of space, and carefully planned for the purpose. They are more or less fire-proof, slow-burning, or briskly combustible, like the dwellings they have devastated.
I am the more confirmed in the opinion that ammoniacal manures are unfavourable for wheat, by a series of articles in the "Gardener's Chronicle" on the "Geo-Agriculture of Middlesex," in which the writer states that land in that county which in Queen Elizabeth's time produced such good wheat that it was reserved for her especial use, will now scarcely grow wheat at all, and when that grain is sowed upon it, the straw is always mildewed, and the sample very poor; and this is attributed and no doubt justly so to the extensive use of London manure.
All the alcoholic ferments are not capable to the same extent of development by means of phosphates, ammoniacal salts, and sugar. There are some whose development is arrested a longer or shorter time before the transformation of all the sugar.
Eder has for a considerable time directed especial attention to the soda and potash developers, either of which seems to offer certain advantages over the ammoniacal pyrogallol.
His ears assailed with horrors, of which you have literally no conception, or shadow of a conception, his nose poisoned with ammoniacal vapours, and the peculiar wild-beast smell that marks the true maniac, Alfred ran wildly about his cell trying to stop his ears, and trembling for his own reason.
But hurrah for this ocean it's ammoniacal copper sulphate solution! We can sure get all the copper we want, right here, but it would take weeks to evaporate the water and recover the metal. We can probably get it easier ashore. Let's go!" They started off just above the surface of the ocean toward the nearest continent, which they had observed from the air. Nalboon of Mardonale
Since the calcium phosphate of the apatite is also insoluble in ammoniacal solutions, this procedure cannot be applied directly. The separation of the phosphoric acid from the calcium must first be accomplished by precipitation in the form of ammonium phosphomolybdate in nitric acid solution, using ammonium molybdate as the precipitant.
According to the experiments which have been made up to the present time, it has been found that the separation of copper is best effected in a nitric acid solution, while that of nickel and cobalt takes place most readily in an ammoniacal solution, and for the precipitation of zinc and cadmium a potassium cyanide solution is the best.
