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.
