Exhibition of Paintings at Paris.

217

The prospectus of a new work has been circulated at Paris, entitled Annales de l'Industrie Nationale et Etrangère, ou Mecure Technologique. These annals will be divided into two parts; one to contain a description of the collection of the production of French industry, exhibited at the Louvre in 1819, and a comparison of them with the works of foreigners; and the opinions of the neighbouring nations on the productions of French industry. Not only will the articles be analyzed and enumerated, but it is designed to lay open the means employed in their fabrication, devoid of technical language, so that they may be universally comprehended. The second part of the publication will contain memoirs on arts and measures, manufactures, commerce, agriculture, and every branch of human industry; together with accounts of machinery, &c. Five or six plates are to be given in each number; of the merit and usefulness of which, to the public, no doubt can be entertained. To such an undertaking, if conducted with spirit and talent, we cannot but wish every possible success.

Exhibition of Paintings, &c.

The Exhibition of Paintings, &c. this year contained 1715 articles; of which 1372 were landscapes, portraits, &c.; 158 statues, busts, and bas-reliefs; 171 engravings and designs; 14 plans and architectural models. The minister of the royal household ordered fifty paintings, twelve statues or bas-reliefs, and three engravings; the Duke of Orleans, two; the minister of the interior, eighteen paintings, nineteen statues or busts, and two models; the prefect of the Seine, twelve paintings, and six statues.

The king of France has given 150,000 francs for the zodiac of Denderah. Before its proprietors parted with

it, they engaged M. Gau to make correct drawings of all the figures that are yet discernible on the stone. From these drawings an engraving is to be executed, which will afford a faithful index of the astronomical signs of the ancient Egyptians.

Lithography.

A. M. Malapeau has obtained a patent for a lithographic process, by means of which oil paintings may be printed off; since which numerous applications of the process have been made, all of which have, it is said, perfectly succeeded.

ITALY.

Prussic Acid.

A SERIES of experiments has been made, by a company of associated physicians, surgeons, and naturalists, at Florence, to determine the best state of the hydrocyanic, or prussic acid, for medicinal purposes. The experiments were made on rabbits, and these scientific gentlemen draw the following conclusions :-That the essential oil of the prunus lauro-cerasus is to be preferred, in medical practice, to all other preparations which contain hydro-cyanic acid: for, unlike the distilled water of the plant, and pure prussic acid, it contains the same power, whether recently prepared or old, whether made in one place or another, after exposure to the air, to light, or to heat. That the oil of olives, or of almonds, is the most proper vehicle, in the proportion of an ounce to twelve drops of the essence, or in a smaller dose, when employed by friction externally.

Machinery for preparing Dough.

SWITZERLAND.

Machinery for preparing Dough.

219

A machine has been lately introduced at Lausanne for the fermentation of the dough for bread, consisting simply of a deal box, one foot in breadth and height, and two in length. It has supports, on which it is turned by a handle like the cylinder used for roasting coffee. One side of the box opens with a hinge to admit the dough. The time requisite to produce the fermentation depends on the temperature of the air, the quickness of the turning, and other circumstances. But when the operation is performed it is known by the shrill hissing of the air making its escape, which generally happens in half an hour. The dough by these means is always well raised. The labour is slight; for such a machine as here described may be turned by a child. No hooks, points, cross-bars, nor any other contrivance, is wanted within the box to break or separate the mass of dough, this operation being sufficiently effected by the adhesion of the dough to the sides of the box.

One advantage amongst others in this process of fermentation is its cleanliness. We are not, however, told whether the flour be mixed only with water in this operation, or whether yeast be added to it: if without yeast, this must be, on many accounts, advantageous and deserving of attentive consideration, as an economical process. The mode of mixing the flour with the water is not stated. Is all the flour added at once to the water; or is a thin pap or paste first made and agitated in the box, which we suppose it should be, till the fermentation is excited, and afterwards more flour added?

AMERICA.

THE Academy of Arts and Sciences at Boston has published a series of observations, of great interest, in Meteorology. They are the results of thirty-three years, made from 1786 to 1818, at Salem, in Massachusets; by which the difference of the temperature of the old and new world is ascertained.

Russian Voyage of Discovery.

LIEUT. CHRAMTSCHENKO discovered, on his voyage in 1821, a small uninhabited island in 59° 28′ 28′′ N. lat. ; and 164° 56' 3" lon. from Greenwich. Capt. WASSILIEU, of the ship Discovery, has also discovered, in 50° 59′ 57′′ N. lat.; and 193° 17′ 2′′ lon. from Greenwich, (it is not stated whether east or west,) an inhabited, and hitherto unknown, island, forty Italian miles in length. It may be presumed, that the inhabitants are the same race as the Aleutiahs; for Capt. W. conversed with them by the Aleutian interpreter on-board. The natives call the island, Nuniweh; Capt. W. called it Discovery. Capt. W. sailed, on the first of February, in the preceding year, from the harbour of San Francisco, and had reached 71° 7' N. latitude; that is, nineteen minutes farther than Cook. He kept constantly along the northwest coast of America, and discovered two capes; to which he gave the names of the celebrated navigators, Golownin and Ricord.
