As soon as Mademoiselle de Verneuil had turned the creaking hinges of the lower door she smelt an intolerable ammoniacal odor, and saw that the beasts in the stable had kicked through the inner partition which separated the stable from the dwelling. The interior of the farmhouse, for such it was, did not belie its exterior.
In this way they effect the decomposition of the tartrate, from which they must necessarily obtain the carbon of their food without which they cannot exist, while the nitrogen is furnished by the ammonia of the ammoniacal salt, the mineral principles by the phosphate of potassium and magnesium, and the sulphur by the sulphate of ammonia.
To win that tribute slaves toil, and, toiling, die, in Brazilian diamond mines, and thousands of coolies, entrapped by agents in China and India, enter into perfidious contracts which commit them to hopeless slavery and send them to wear out their lives in despairing toil amid the pungent and murderous ammoniacal fumes of the guano islands of Chili and Peru.
We have yet to say a few words concerning the useful ammoniacal liquor, and the final residue in the retorts, i.e., coke.
Again, if ammoniacal gas is reduced by a compressing force to one-sixth of its volume, or carbonic acid is reduced to one thirty-sixth, a portion of them loses entirely the form of a gas, and becomes a liquid, which, when the pressure is withdrawn, assumes again in an instant its gaseous state another deviation from the law of Marriotte.
This advantage becomes particularly apparent with emulsions prepared with ammonia, which frequently show with ammoniacal developer green or red fog, or a fog of clayish color by reflected, and of pale purple by transmitted light. Ferrous oxalate works quite well with plates of that kind; so do soda and potassa developers.
Five guano-bags were packed, each with its bundle of gold, but the task was a disagreeable, almost a distressing, one, for the strong ammoniacal odor sometimes almost overpowered the captain, who had a great dislike for such smells. But he never drew back, except now and then to turn his head and take a breath of purer air.
The Academy may remember that I stated before it, and the fact has never been denied, that ammoniacal urine is always produced by a microscopic organism, entirely similar in many respects to the organism of furuncles. Later, in a joint investigation with M. Joubert, we found that a solution of boric acid was easily fatal to these organisms. After that, in 1877, I induced Dr.
The microbes that fix the nitrogen of the air and those which convert the ammoniacal compounds into nitrous ones, and these again into nitrates, have, by the same splitting up of a tendency primitively one, rendered to the whole vegetable world the same kind of service as the vegetables in general have rendered to animals.
Thus, for example, manganese is slowly deposited from an ammoniacal solution, when it is permitted to take up oxygen from the air, as hydrated sesquioxide, and from neutral or alkaline solutions, as hydrated peroxide on the addition of chlorine, bromine, or chameleon solution.
