The French papers state that the Minister of Agriculture and Commerce has formed a commission of painters, architects, &c., to propose reforms and improvements, both industrial and artistic, in the national manufactures of the Gobelins, Beauvais, and Sèvres. The Sketch-book by Salvator Rosa, Northampton's third Soirée for the season-the exhibited on 1st April at the Marquis of property of Mr. Auldjo-was more remarkable for the notes on the margins and backs of the several studies than for any intrinsic merits of the sketches themselves. They are chiefly transcripts of the neighbourhoods of Spoleto and Foligno; and deficient in that savage character which is the painter's expressive style.

POSTSCRIPTS

THE ensuing number of this work will form the first of a new volume; and with that number will be commenced a variety of improvements which cannot fail of giving satisfaction to our readers. Among these we may particularly mention the abolishment of the advertisements hitherto printed on the two first pages-the space thus gained it being intended to devote to the general purposes of the publication. The designs presented will hereafter be placed on the front page of the weekly numbers; and, in order to inhance their appearance, no type will be printed on the back. We may here announce that we have a series of articles on each of the following important subjects in active preparation :

We also intend presenting elaborate series of articles on the contents of the British Museum, the National Gallery, the Dulwich Gallery, the Armoury of the Tower of Londen, and the Hall of the Royal Polytechnic Institution, in addition to others of general interest; Editorial Notices, Reports of Artistic and Scientific Meetings, History, Sculpture, and Reviews of New Books, with copious Extracts.

The articles on Architecture will be rapidly followed up, and will embrace all the orders, styles, and varieties from the earliest period to the present day.

Scarce and valuable Essays on Art and Science will appear in our pages in an abridged form.

Most of the above will be illustrated by first-rate engravings.

Having secured the services of several eminent artists, we shall be enabled to lay before our readers weekly an elaborate design of a high order of merit.

Notwithstanding the heavy pecuniary outlay which these improvements will necessarily entail upon us, no advance upon the usual price of this publication will be made; all that we desire of our readers being, that they strive to introduce our work to the notice of their friends. If every one of our present subscribers were but to obtain two extra purchasers, we should be enabled to perform even more than we have promised-and there are, we believe, none that have it not in their power to do so.

In taking leave at the conclusion of this volume, we again have to return our sincere thanks to those who have supported us in our past labours, and cheered us on, by encouragement and suggestion, towards the great end we have in view-the cultivation and improvement of the minds, the feelings, and the tastes of the multitude-the correction of abuse-the furtherance of art-and the dissemination of its principles widely and freelyconceiving it to be, in these days, a noble and a creditable labour, and one deserving of more patronage than we have hitherto received at the hands of the public. 17, Holywell Street, Strand, London.
