" Account of a variety of Argillaceous Limestone found in connec- 

 tion with the Ironstone of Staffordshire," by the Rev. James Yates, 

 M.A. (Trans. Geo. Soc, vol. v., 1819, p. 375). — Describes this as a 

 variety of limestone called by the miners Curl. It was inspected at 

 the Coppice Mine (near Coseley ?) It contains small veins of calc spar 

 passing vertically and without interruption through both ironstone 

 and curl beneath it. It has recently been employed in considerable 

 quantities for making Roman cement. It occurs in Shropshire, as 

 mentioned by Mr. Aikin, and at the Ketley ironworks was used for a 

 time as a flux. Mr. Sowerby has given two representations of this 

 inineral in his " British Mineralogy," vol. ii., plates 148, 14i), and he 

 states that it occurs near Sunderland, at Bartonsel, at Cumberland, at 

 Boxilby in Yorkshire, and in Derbyshire. The variety found in 

 Derbyshire is described and figured in Martin's " Petrifacta Der- 

 biensia," AVigan, 1809, plate 27, fig. 4. It is found immediately 

 above and attached to a stratum of ironstone which extends from 

 Tupton Moor to Staveley. Incidentally it is mentioned in the paper 

 that Werner gave to this substance the name of Dutenmcrcjcl or funnel 

 marl, and that it occurs at G'ororps Mill, in Shoenen, and in the island 

 of Bornholm, near the town of Ronue.

" Notice on the Black Oxide of Manganese of Warwickshire," by 

 S. Parkes. (Trans. Geo. Soc, second series, vol. i., 1824, p. 168). — 

 The specimens exhibited to the Society were found at Harts- 

 hill, near Atherstone. The manganese occurs in detached pieces 

 distributed through the clay, weighing from one to fifty or sixty 

 pounds each, and from one foot to six or eight feet below the surface 

 of the ground. The first manganese was found on the estate of 

 T. L. Ludford,Esq., of Ainsley Hall, about two miles from Atherstone. 

 A poor man of the name of Hankinson, who possesses a small field 

 adjoining Mr. Ludford's estate, has since found manganese in his 

 land, and has raised a considerable quantity. A man of the name of 

 Davis has also raised some, and sold it at a good price to the bleachers 

 in Lancashire. Dr. Power, of Atherstone, has taken a great interest 

 in the discoverv.

" On the Mineralogy of the Malvern Hills, " by Leonard Horner, 

 Esq. (Trans. Geo. Soc, vol. i., p. 281). — A description of the hills is 

 given, and afterwards in speaking of the unstratified rocks reference 

 is made to the minerals occurring in the rocks. " A great part of the 

 End Hill is composed of granite, particularly on the west side, where 

 it contains veins of quartz in several places. In the same part of the 

 End Hill, but at a higher elevation than the granite, there is a rock 

 which prevails very much throughout the whole range. It is of a 

 purplish brown colour, with a fine close grained texture and an uneven 

 fracture. It is composed of hornblende, felspar, and a little quartz ; 

 sometimes contains a small quantity of magnetic pyrites, and slender 

 ^eins of compact epidote ; in the fissures of it cr\stallised sulphate of
