NEW BLOW-PIPE.

The new blow-pipe, acting by a steam of condensed oxygen and hydrogen, has deservedly excited much interest. Mr. J. Murray, who is engaged in a series of experiments on the subject, says that the oxygen was obtained from oxymuriate of potassa, and the hydrogen from water decomposed by zinc, &c.-the proportions such as form the constituents of water. Mr. Murray gives a detail of some of his experiments: 1. Platinum, as thick as a stocking-wire, was instantly fused, scintillated, and fell in a large globule. 2. Palladium fused instantly, and slightly scintillated. 3. A watch-spring melted with the most splendid corruscations, fused into a large globule, and even boiled violently. 4. Pure caustic alumina and magnesia burnt with indescribable brilliancy, exhibiting a splendour of light, rivalled only by the sun. 5. Part of a tobacco-pipe burnt vividly, and was fused into glass. 6. A piece of indigo exhibited a beautiful and intense flame. 7. A fine electric tourmalin grew red-hot, instantly fused and flamed. It did not forego its electric powers. 8. The diamond, in a groove of charcoal, was submitted to its influence. In a short time it became red-hot, then burst into flame; and, when dislodged from its nidus, it fell upon the table, and continued, a second or two, in actual flame. 9. A mass of percarburet of iron (plumbago) gave beautiful minute sparks, and was fused. 10. Rock crystal decrepitated violently.

MODE OF MELLOWING WINE.

Academy of Sciences at Munich.-M. S. T. Von Soemmering has recently read a paper on a new mode of improving or mellowing wine. The improvement recommended consists in this, that wine should be kept in glass vessels, having their orifices closed with bladder, as the means of mellowing, or imparting to

it the advantages of age, in a short time. The experiment chiefly relied on is the following:-four ounces of red Rhenish wine, of the growth of 1811, on the 21st of December, 1812, were put into a tumbler of common white glass, three and a half German inches deep, and two and a half wide. This was secured by a well prepared bladder, softened by steeping, and placed on a shelf, out of the reach of the sun, in a common sitting-room. The spaces comprised by two and four inches were marked on the outside of the glass by lines. The glass was opened, upon perceiving that two ounces of the wine had escaped through the dry bladder; which was the case in the space of eighty-one days. The following observations were made on the remaining wine:—1. It was neither mouldy nor mothery, as it would have been, had it been left uncovered, or even stopped with cork for the same length of time, in the same kind of glass, in the same situation. 2. Dry crystalline crusts or pellicles were perceived floating on its surface. These were found to be ordinary cream of tartar, from their sinking to the bottom, on the wine being slightly shaken; from their being seen, through a magnifier, to consist of aggregated crystals; by their reddish colour and semi-transparent substance; by their gritting between the teeth; by the sour taste peculiar to that substance, as well as by their emitting the same smell as that, when burning, and depositing the same kind of ashes. The quantity was too small for further chemical tests. 3. A cream of tartar, precisely similar, had subsided to the bottom of the glass. 4. The wine was of a darker colour, yet brighter and finer than the same sort bottled in the customary way, and which, of course, had undergone no evaporation. 5. In smell, its flavour was stronger and more enticing than that of the same wine ordinarily bottled. 6. In taste, its flavour, though more spirituous and aromatic, was still, in another way, milder, softer, and more grateful to the palate, or, in other words, mellower than that of the other. 7. Its proportion of alcohol was one half greater than in the ordinarily bottled wine of the same growth.

Wine, concentrated in the same way, was afterwards submitted to closer tests, and experiments were repeated on some of a different kind, but still red; and these results were uniformly confirmed. It was known that water escaped through dried bladder;

but that it did not admit an equally free and ready passage to the spirituous portion of wine as to the aqueous, seems a new, and not unimportant discovery. By this treatment of wine, no extraneous alterative is used, and it is left to rid itself spontaneously of the superfluous, coarse, sharp, sour salts, by the evaporation of the water in which they are held in solution.

Wine, left standing upright in a half-emptied bottle, either open or ever so well corked, for several weeks together, will spoil, and become mothery and sour. By closing the bottle with bladder, wine (red only has been tried) may be preserved under the same circumstances, for a year together, without any such consequences. If the mouth of the bottle should not be larger than ordinary, we may be sure that, in a year's time, the quantity of half an ounce will not have been wasted, and the remainder not only be uninjured, but rather improved. The degree of improvement of mellowness, which is induced by the wine being treated in this manner for twelve months, is said to be equal to that which would be produced, in the cask, in twelve years. The shallower the glass, and the wider its orifice, the sooner the same effects are produced. Another advantage is, that in the glass vessel we can always perceive the degree of evaporation that has taken place, and regu late the process at will. It is suggested, that some interesting results might probably arise from the examination of the gas found between the surface of the wine and the bladder, at different periods, during the process of evaporation.

LITERARY INTELLIGENCE.

1. FOREIGN. The Private Correspondence of Dr. Franklin has just appeared in London. It comprehends a series of familiar, literary and political letters, written between the years 1753 and 1790, now first published from the originals in the possession of his grandson, William T. Franklin. One vol. 4to. 21. 2s. bds. Among the characters of high name, in the literary and political world, whose letters and sentiments are here recorded, may be mentioned Washington, Burke, Fox, Priestley, Price, Banks, Brand Hollis, Granville Sharp, Baron Masseres, Buffon, Becca

ria, David Hartley, bishop Shipley, earl of Buchan, lord Shelburne, lord Grantham, &c. We saw a part of this work some time ago, and have waited with the most eager impatience to see its republication announced in this country-Purity of Heart, or the Ancient Costume, a tale addressed to the author of Glenarvon, by an old wife of twenty years.-The London booksellers announce the publication of a journal in 4to, entitled the PORT FOLIO, political and literary; being a general miscellany and collection of original and fugitive productions, &c. We have, at home, a Juvenile Port Folio, in this city, and another in some part of Ohio. The Rev. Dr. CHALMERS, of Glasgow, is printing a volume of Discourses, in which he combats, at some length, the argument, derived from astronomy, against the truth of the Christian religion; and, in the process of his reasoning, he attempts to elucidate the harmony that subsists between the doctrines of scripture and the discoveries of modern science.-Part III. of the ENCYCLOPEDIA EDINENSIS, by Dr. Miller, is out. The learned Mr. Valpy has in the press, a new edition of the Greek SEPTUAGINT, without contractions.-Homer, from Heyne's text, with English notes, is also promised by the game indefatigable scholar. The second number of Stephens' Greek THESAURUS, was to appear in January. Dr. Taylor announces a translation of the first six books of PROCLUS, on the theology of Plato; to which a seventh book is added, in order to supply the deficiency of another book on this subject, which has been lost, also the Elements of Theology, On Providence and Fate, Ten Doubts concerning Providence, and on the Existence of Evil, by the same writer, and other works of unintelligible mysticism.-We notice further, among the new publications, a new edition, with additions, of lord Holland's life of Lopez de Vega, Dr. Watkins's life of R. B. Sheridan, the life of Raphael of Urbino, of Edward Pocock, the celebrated orientalist, Dr. Zachary Pearce, bishop of Rochester, and of Dr. Newton, bishop of Bristol, by themselves.-A map of Scriptural and Classical Geography, with an explanatory treatise, wherein the documents of sacred and ancient civil history, relative to the origin of nations, are discussed.--The History of the Island of Ceylon, from the earliest period to the year 1815; with characteristic details of the religion, laws and manners of the
