Revelations of Hungary, by the Baron Prochazka, presents the Austrian view of the question with more zeal than ability. The author details with the utmost complacency the fearful atrocities of the campaign, wondering all the while that the Austrians were hated by the oppressed population. Appended to the Revelations is a "Memoir of Kossuth," designed to instruct the world as to the true character of the illustrious Magyar. Every good quality which has been attributed to him, from genius down to personal beauty, is vehemently disputed. The world is assured that "Kossuth is by no means the handsome man his partisans represent him to be; he is of middle stature; his figure is insignificant; his hair was brown, but being bald, he wears a wig of that color." This last allegation, we fear is too true; for Kossuth lost not only his hair, but his health and every thing but life, hope, and honor during his imprisonment in Austrian dungeons.

The Correspondence of Sir Isaac Newton and Professor Cotes, edited by J. Eddleston, M.A., presents a view of all the ascertained facts in the personal and intellectual history of the great mathematician. When he was engaged in elaborating his theory respecting light and color, in order "to quicken his faculties, and fix his attention, he confined himself to a small quantity of bread during all the time, with a little sack and water, of which, without any regulation, he took as he found a craving or failure of spirits."

A continuation of the Dix Ans of Louis Blanc has been commenced by M. Elias Regnault, under the title of L'Histoire de Huit Ans, 1840-48.

The London Leader speaks of a new work by Harriet Martineau and Mr. Atkinson which is likely to excite attention. It is entitled "Letters on Man's Nature and Development." The Leader having read a few of the proof sheets, says that for boldness of outspeaking on subjects usually glozed over, and for power of philosophic exposition, it has few equals. The marvels of mesmerism and clairvoyance are stated with unflinching plainness, as facts admitting of no dispute. Materialism is unequivocally and even eloquently avowed; and phrenology assumes quite a new aspect from the observations and discoveries here recorded.

The London Critic contains an interesting paraagraph giving an account of the payments made to authors in France. It is said that Lamartine, for the single volume of his Confidences, received 8000 dollars. Chauteaubriand, a few years before his death, contracted with a company to sell them, at the price of 4000 dollars per volume, any new works he might write and desire to print. Victor Hugo, by contract with the publishers, is paid 3000 dollars for each new volume with which he may furnish them. De Balzac, in 1837, entered into a contract with his publisher, Delloye, by which the publisher acquired the property for fifteen years of the works of De Balzac at that time published. The pecuniary consideration paid to the author, was 12,000 dollars cash, and an annuity of 3000 dollars. Eugene Sue sold for 9600 dollars the right of publishing and selling, during five years only, his novel called Martin the Foundling, or the Memoirs of a Valet de Chambre. The work was already in course of publication in the feuilleton of The Constitutionnel, and the purchaser's rights were confined to France. It was the Mystères de Paris that made the great literary name and fortune of Eugene Sue. Previously the remuneration of his literary labors was much more modest. La Salamandre was disposed of at 300 dollars per volume. The Wandering Jew, and Les Mystères de Paris, were sold at 20,000 dollars the volume: and the purchaser made 12,000 by the operation. In August, 1845, The Constitutionnel, wishing to secure M. Sue exclusively to itself, made with him a contract which was to last for thirteen years and a half. By its terms the author bound himself to furnish for publication in the feuilleton of The Constitutionnel not less than four, nor more than six volumes of novels per annum, for which he was to be paid 2000 dollars per volume on delivery of the manuscript.

Lamartine seems determined to surpass the literary fecundity of James, or even, if such a thing be conceivable, that of the renowned Alexandre Dumas. In addition to his History of the Directory, mentioned in our last number, it is announced that he has contracted to write a History of the Restoration, in some eight or ten volumes. The Leader, which is good authority on these matters, however, states that this last is substituted for the History of the Directory, which Lamartine abandoned in disgust when he found that Garner de Cassagnac had undertaken the same subject for feuilleton publication. A romance, after the manner of Genevieve, is advertised to appear in the feuilleton of La Presse. He has long been under engagements to furnish, under the title of the Conseiller du Peuple, a monthly pamphlet on current political events; and he is said to have engaged to write another similar one every fortnight. Finally, he has in contemplation a History of Turkey. He is, moreover, an active member of the Legislative Assembly, and a frequent speaker. During one of the late ministerial crises he came very near being placed at the head of the Ministry. With such a number of engagements, undertaken under the pressure of pecuniary necessities, it is not to be wondered that his recent productions have been unworthy of his former reputation.

Dr. J. F. Schröder has produced a unique work on Talmudic and Rabbinic maxims and usages. As a specimen of these, we give some of the refinements and distinctions relating to the observance of the Sabbath: "Hunting is totally forbidden on the Sabbath, and since fly-catching is a species of hunting, it is prohibited—nay, the prohibition extends so far, that a Jew must not cover vessels in which there are flies, because in this way a sort of catching might take place. Fleas must first have bitten before they may be caught; and it is not allowable to kill them when caught. A louse found on the body may be killed, but not one that has taken up its abode in the outer parts of the garments. Animals, on the contrary, which are tame and willingly allow themselves to be taken, may be caught even on the Sabbath; some, however, consider this not allowable. An egg laid on the Sabbath, or fruits which have been plucked on that day, may not be used.... If any body wishes to borrow any thing of another on the Sabbath, he must not say, 'Lend me this or that;' but 'Give it me, and I will give it you back.' If a pledge is to be restored, the lender must lay it down in silence. He who wishes to have some beer or wine on a Sabbath, must not say to the tavern-keeper, 'Give me so much wine or beer for so much money;' but 'Give me the vessel full or half full.' After the Sabbath the vessel may be measured, and the value of the wine or beer received may be determined. Letters must not be either written or opened on the Sabbath; but if any one not a Jew has opened them, without having received orders to do so, and one is anxious to know the contents, they may be read; but the words must not be uttered aloud. News also may be read in this way. Accounts, on the contrary, bills of exchange, and such things, relating to trade, may not be read. If a leg, &c., falls out of a chair or bench on the Sabbath, the injury must not be repaired on that day. Should a wine-cask or any thing of that sort begin to leak, a vessel may be put under it, but the hole must not be stopped up."

Charles Knight, the eminent publisher, in an effective pamphlet advocating the repeal of the paper-tax, presents some facts showing the bearing of that tax upon the diffusion of knowledge. He has had in contemplation a Supplement to the National Cyclopædia, to consist of a series of treatises upon Scientific, Social, and Industrial Progress, to extend to four volumes. To produce this as it should be done, he must secure the assistance of the most eminent men in every department of knowledge; which assistance will cost £2000. To cover the outlay he must sell at least 25,000 copies; which will consume 6400 reams of paper, the duty upon which would be £880. This additional expense, adding nothing to the value of the work, makes him hesitate to embark in the enterprise, If this burden were removed he might either save it in the original cost, or expend it in adding to the value of the work. In either case he would not hesitate to carry out his design.

Robert Chambers shows the bearing of the same tax upon labor. His Miscellany of Tracts was stopped as not paying, although it had a regular sale of 80 000. While published it had paid a paper-tax of £6220. This publication, which might have been continued had it not been for this tax, distributed £18,000 a year in labor. He had since started a similar series at three halfpence, of which, owing to the increase in price, only half as many were sold as the other. It is calculated that this tax keeps out of employment, in London alone, full 40,000 people. The whole value of the paper annually manufactured in the kingdom is estimated at £4,000,000, upon which a duty is laid of £800,000. This is levied almost entirely upon labor, the mateterial used being almost entirely without value.

Leopold Ranke, author of the History of the Popes, in the course of his researches in the National Library at Paris, has discovered a manuscript portion of the Memoirs of the famous statesman Cardinal Richelieu, which has long been supposed to be lost. In the manuscript deposited at the French Ministry of Foreign Affairs, a series of leaves is wanting. These Mr. Ranke found by accident in a bundle of old papers. It is thought that this discovery may throw some light upon the disputed question whether the cardinal was the actual author of the works which are attributed to him, or merely revised and corrected them.
