Scientific Miscellany.
A Report by five eminent members has been made to the Paris Academy of Sciences, on a paper from Colonel Lesbros, entitled Hydraulic Experiments relative to the Laws of the Flowing of Water. Two thousand experiments, carried through four years, are detailed in three hundred and twelve pages of text, with thirty-seven large plates. The work was recommended to the Academy by the Minister of War. The Committee say, at the end of their report:—"Considering the high utility of these experimental researches, prosecuted to the end in the most satisfactory and complete manner; and being convinced of the beneficial effect which the publication of them may have in the promotion of science, and its application to public works,—to navigation, agriculture, hydraulic establishments, and the various branches of industry connected with them,—the Committee are of opinion that the Academy should accord full approbation to the work, and direct the early insertion of it in the Transactions." All parts of the report show that the publication will be of importance to both sides of the Atlantic.
Of the December number of the Comte Rendu of the Paris Academy of Moral and Political Sciences, nearly twenty pages are occupied by one of the Reports of Blanqui, the Political Economist, on the Rural Populations of France. He made his personal survey, this year, as Commissioner of the Academy. He is preparing a work, in several volumes, on the state, in every particular, of the inhabitants of France, in every part. His abstract of his recent survey of the Departments of the centre, including the basin of the Loire, abounds with curious details, especially as to the diversity of the manner in which the Revolution of February, 1848, affected the rural and city populations in their minds and interests. He speaks of the city of Saint Etienne as extemporized after the American fashion.
The African Exploring Expedition.—Intelligence has been received from the Saharan African Expedition up to the 29th of August last. The expedition had literally fought its way up to Selonfeet in Aheer, near to the territory of the Kaillouee Prince, En-Nour, to whom it is recommended. Mr. Richardson had been obliged to ransom his life and those of his fellow-travellers twice. The whole population of the northern districts of Aheer had been raised against the expedition, joined by all the bandits and robbers who infest that region of the Sahara. The travellers are now in comparative security. The great Soudan route, from Ghat to Aheer, is explored. Of the expedition of Von Muller we have a few days later but not important news.
The Royal Society of London, at the last annual meeting, awarded "the Royal Medal" to Mr. Benjamin Brodie, F.R.S. (eldest son of Sir B. Brodie, Bart.) for his papers on the chemical nature of wax. It is nearly forty years since the Royal Society awarded the "Copley medal" to Sir Benjamin Brodie for his paper "on poisons;" the only instance of father and son receiving the same distinction.
Of an Hungarian Academy, Mr. Walsh writes to the Journal of Commerce, "Last month Mr. Kenigswater transmitted to the Academy of Moral and Political Sciences, a very interesting communication relative to the National Academy of Hungary, with the existence of which few of the French savants were acquainted. The idea of establishing a National Society for universal knowledge, dates from the end of the last century. Its accomplishment was delayed by political causes, and the want of adequate funds. But a Magyar Count succeeded, in 1827, in obtaining an act of the Diet for the creation of such an institute. He presented it with a sum of thirty thousand dollars; another magnate gave twenty thousand dollars; many others ten thousand; so that the fund from voluntary contributions, amounts to nearly two hundred thousand dollars—a million of francs. The Academy was inaugurated in 1830, and divided into six sections—Philology, Philosophy, History, Jurisprudence, Mathematics, and the Natural Sciences. Its only President since that period has been Count Joseph Teleki, deemed an excellent historian, to whom and his brothers it is indebted for a sum of twenty-five thousand francs, and a library of fifty thousand volumes. It consists now of nineteen honorary members; thirty-eight active or resident; and of a hundred and twenty-five corresponding members for the several sections. Each section has a weekly meeting; there are monthly and annual sittings of all. Papers on erudite and scientific subjects are read; the Magyar language is alone permitted in its business and transactions, except as to the communications of its foreign correspondents. It has published, at its own expense, a very large number of works; among them a series of critical Commentaries on the ancient monuments of the Magyar language, "which bears no affinity to the European tongues, and differs as much from the Sclavonic as from the Teutonic and the Latin idioms." There is a very important and very rich collection of Hungarian translations of the Latin and Greek classics; another of translations of the principal modern dramatic authors. The Hungarian mind has been prolific for its stage, in original pieces. The Academy awards prizes, confers distinctions, &c., &c."
