Crystallization.

A paper on this subject, by F. DANIEL, Esq. was read to the Royal Society in November, 1815. It was an Inquiry into the Process of Crystallization, and the effects of Solution on the structure of Crystals. In this paper he showed that the action of water and other solvents upon crystals was a much more delicate test of their structure than mechanical division. From these experiments, he is inclined to consider Dr. Woollaston's theory of molecular sphericity as satisfactory, and better adapted than any other to explain the phenomena of nature. He also regards it as an additional proof of the infinite wisdom of the great author of nature, that the molecules of our globe should have the same form as those stupendous orbes which constitute the heavenly bodies.

DR. J. R. COXE has also made some experiments on the crystallization of salts, which in some respects contradict the generally received opinious respecting that process; but the results he obtained were so uncertain and irregular, that he could in no case anticipate them with certainty. He thinks, however, that his experiments fully disprove the theory of latent heat, as water saturated at the temperature of 212° remained fluid and transparent, even at the freezing point, although the theory ascribes its solvent power to the temperature.

Electricity.

MR. EZ. WALKER, in his New Outlines of Chemical Philosophy, published in the Phil. Mag. states the following to be the General Properties of Electricity.

"1. That the mechanical forces of those elements which produce a spark are equal, moving through each other; but the spark so produced is not an element, but the effect of those invisible elements which are brought into action by the motion of the machine. But no spark can be produced, unless those elements pass through some conducting medium.

"2. The true electrical elements exist together in all bodies which may be called their natural state.

"3. Two bodies electrified with contrary elements attract each other strongly, although an electric plate be interposed between,

them.

"4. Two bodies electrified with the same element repel each other, although a thin electric plate be interposed between them

Prussic Acid.

M. GAY LUSSAC has lately made an important set of experiments on Prussic acid, and obtained the following results. See Annals of Philosophy, No. 36. His analysis shows that Prussic acid is composed of

Prussic acid cannot be kept; and is considered as composed of a radicle, consisting of two atoms of carbon and one of azote, combined with oxygen. This radicle may be obtained in a separate state; and therefore Prussic acid is composed of equal volumes of radicle and hydrogen gas, without any diminution of bulk. Gay Lussac has given the name of cyanogen to the radicle, and that of hydrocyanic acid to what was formerly called prussic acid.

Quicksilver Mines.

M. PAYSSE has published in the Annales de Chémie, vol. xci., a statistical account of the quicksilver mines of Idria in Illyria. He was superintendant of the manufacture of mercurial productions, during the time these mines were managed by the French Government; which was from January 1st, 1810, to September, 1813. During these three years and eight months, there were sublimated in the furnaces 198,176 quintals 54 pounds of various ores, which produced 17,076 quintals and 54 pounds of quicksilver; which at the regulated price of 130 Austrian florins per quintal, amounts to 2,219,945 florins, or 5,740,463 francs.

There was actually delivered into the magazines the following quantities of quicksilver, or of mercurial preparations: viz.

Quintals.
14,194

The expenses of the establishment amounted to 800,000 francs per annum; hence the average profits were 713,409 francs annually.

There are about 700 hundred miners, and 300 woodcutters employed, and nearly 600 pensioners including widows and children. The pensions amount to 50,000 francs per annum.

Poison.

Copious draughts of milk have been found a remedy for the poison of false mushrooms This produced long and violent vomitings on a family of six persons who had ate plentifully of these; and in a few hours after, the whole were declared out of danger.

The juice of lemons and other vegetable acids, have also been found a remedy for the effects of opium.

Meteorology.

The following are Mr. Luke Howard's results from the 25th of October, to the 22nd of September inclusive.

Prevailing winds northerly, but interrupted soon after the middle of the period by a southerly current, which greatly depressed the barometer, and was followed by a sharp frost.
