The following gratifying report of the directors has just been made:--"The funds of the institution consist at the present time of 12,500l. 3 per cent, consols. It is hoped that these funds may be considerably increased by the exhibition of the beautiful collection of pictures now on view at the gallery, which last year attracted such general notice, and which his majesty, ever anxious to forward the purposes of the institution, has again allowed the directors to offer for the inspection of the public. The directors, finding that the two institutions which have been established for the relief of decayed artists, were not only founded upon the most humane principles, but conducted in the most beneficial manner, have applied in the course of the present year, 400l, to the purposes of those institutions; viz. 200l. to the Artists' Benevolent Fund, and 200l to the Artists' General Benevolent Institution." The report next mentions two pictures to be painted on the subjects of Lord Howe's and Lord St. Vincent's victories, by Mr. Briggs and Mr. Jones, to be placed, "as well as those which were exhibited this year in the gallery in commemoration of other naval victories, in the hall of Greenwich hospital." It also confirms the gift of Mr. Hilton's and Mr. Northcote's pictures to the new church at Pimlico, built by Mr. Hakewill, and to the chapel built by Mr. Cockerell, in the upper part of Regent-street. * * * * * ARTS AND SCIENCES. * * * * * MUSICAL COMPOSITION. A very valuable musical manuscript, by Guillaume de Machault, who was _valet de chambre_ to Phillippe-le-Bel, in 1307, has been discovered in the royal library at Paris. It contains several French and Latin anthems, ballads, &c.; and concludes with a mass, which is supposed to have been sung at the coronation of Charles V., in 1364; and which proves, at that time they were acquainted with the art of composition in four parts. NOISY FISH. M. Cuvier lately read a short paper to the French academy on the species of fish called _pogonias_, in which he particularly adverted to the noise by which they make themselves heard, even under water. However difficult the explanation of this phenomenon, there can be no doubt of its existence; the evidence of it adduced by M. Cuvier being perfectly satisfactory. The silurus, a large and ravenous fish, which abounds in the Danube, gives daily proof of it. GEOLOGY.
