The _Calvin Translation Society_, which for the last ten years has been issuing, at irregular intervals, a complete and very handsome edition of CALVIN'S works, in English--to make about fifty octavo volumes--will have to add to them a new collection of his _Letters_. It appears that the government of Louis Philippe committed the preparation of the Unpublished Letters of the great Reformer to Professor BONNETT, who had been dismissed from the College of Nismes for speaking too highly of Luther. He travelled in France and Switzerland, at the expense of the Government, in order to collect the letters. After the revolution, the influence of the Catholic clergy was such that the new minister of Public Instruction found a thousand difficulties in the way of accepting the labor of M. Bonnett, and the subject was finally referred to a committee, who reported in favor of the publication; yet, to split the difference with the clergy, they, on pretence of a saving of expenses, ordered that some of the less important letters should be omitted, and that the Latin and French letters should be published together in the same volume. The number of Calvin's unpublished letters in the collection is 497; of these 190 are in French, and 307 in Latin. * * * * * The aged LACRETELLE, who of late years has lived in retirement near Macon, reposing upon his fame as an historian, appeared recently at the Academy in that city, on the day when the prizes of the Agricultural Society were distributed, and delivered an oration, marked by the energy and force of youth, but not by its hopefulness. He is now eighty-five years old; and on this occasion, was particularly severe against the communists and socialists, who, he thought, were bent on destroying every thing good, and upsetting the world. This was uttered with a point and bitterness that did no discredit to the censor of the press under both the Empire and the Restoration. * * * * * M. ROMAIN CORUNT has commenced, in _La Presse_, a series of Critical Studies on Socialism, which M. Girardin introduces with a special editorial, and which promises to be valuable. It was not originally designed for publication, but to satisfy its author's curiosity as to the ideas and aims of the revolution of 1848. He has accordingly gone analytically through the writings of all the socialist schools. He commences his exposition with Auguste Comte. * * * * * A FRENCH publisher advertises the memoirs of the celebrated actress Mademoiselle MARS, who died at a great age some half dozen years ago. Like those of Pompadour, Crequi, Dubarri, Fouche, Robespierre, and many others, they will undoubtedly turn out to be a fabrication by some ingenious literary trickster, yet it is probable that they will be amusing. * * * * *
