Much time may often be saved by washing precipitates by decantation, i.e., by pouring over them, while still in the original vessel, considerable volumes of wash-water and allowing them to settle. The supernatant, clear wash-water is then decanted through the filter, so far as practicable without disturbing the precipitate, and a new portion of wash-water is added.
The ready landlord had the cork instantly extracted, decanted the wine into a vessel of suitable capaciousness, and, declaring it parfumed the very room, left his guests to make the most of it.
The same circle of servants of acquaintances revolved around us. The house was unchanged, the living identically the same, even to the one bottle of fine wine per day, carefully withdrawn from the cobwebbed cellar by Morton, and as carefully decanted for our table. But this alone, of all the viands set before us, was furnished at my expense.
From the interior of this bus emerge people; and from the top, by means of a strangely-constructed hooked ladder, are decanted boxes, trunks, and appurtenances of various sorts. In these people, and in these boxes, trunks, and appurtenances, are the real interest of the Grand Hôtel du Louvre et de la Paix of the marvellous Rue Cannebière of Marseilles.
The zinc may be supposed to remove oxygen from the acid sulphite, NaHSO , giving hyposulphite, NaHS0 . The reduction of the acid sulphite is best performed in a cask, which can be closed at the top, so as to avoid entrance of air. The liquid is then mixed with milk of lime, and after again thoroughly stirring, the liquid is allowed to settle, and the clear is decanted into the dyeing-copper.
The outside of the house promised little for the interior, notwithstanding the vaunt of a sign, where a tankard of ale voluntarily decanted itself into a tumbler, and a hieroglyphical scrawl below attempted to express a promise of "good entertainment for man and horse."
It is then discontinued, the mixture allowed to deposit for a few moments, and about two-thirds of the supernatant solution decanted; it is mixed with some more water, and these decantations repeated until they pass away without reaction, or by filtering it and washing on the filter; it is then dissolved in hot hydrochloric acid, this nearly neutralized, a solution of sesquichloride of iron is added, and again treated with an excess of chlorine.
Solutions of nitrate of silver are not carried about and decanted into baths and back again into bottles without tracking their path on persons and things. The photophobia of the "sensitized" plate, of course, requires a dark apartment of some kind: commonly a folding tent is made to answer the purpose in photographic excursions.
The judge had made a speech in honour of the home-coming of the student, the eldest son of the house, and the merchant had replied with another in honour of the judge; so far all was well and good. And yet one could see that the host was disquieted about something. He answered inconsequentially, decanted Rhine wine into port, and betrayed absence of mind in all manner of ways.
It may also be obtained from animal substances, although a vegetable acid. The acid may be obtained from Prussiate of potash, by making a strong solution of this salt, and then adding as much tartaric acid as will precipitate the potash, when the acid will be left in solution, which must be decanted and distilled.
