Shone, W. On the Discovery of Foraminifera &c. in the Boulder- 

 Clay of Cheshire. Quart. Joum. Geol. Soc. vol. xxx. p. 181. 



Fifteen species of Ostracoda were found by washing sand occurring 

 in shells of TurritelJa^ found in the Upper Boulder Clay of Newton-by- 

 Chester ; also Spirorhis nautiloides, fragments of spines of Cidaris and 

 Spatayifjus, and 34 species of Foraminifera, most of which also 

 occurred in the Lower Boulder Clay of Dawpool. Their facies indicate 

 a shallow sea, into which large quantities of fresh water constantly 

 poured ; and the species corresponded to those now living in the tidal 

 reaches of the Dee. C. E. De R.

 Grit Series of the Parish of Halifax, Yorkshire. Trans. Man- 

 chester Geol. Soc. vol. xiii. part vii. 1874. 



The bed of marine fossil shells met with at one of the puddle-dykes 

 of the Castle-Carr reservoirs, and in the tunnel between Sowerby 

 Bridge and Luddenham Foot, belong to the shales lying on the Third 

 (Millstone) Grit series. He describes the Grits of Luddenden and 

 Calder dales and llybourne valley : the Flag Rock or second grit, he 

 places with the first series 350 feet in thickness ; his second grit 

 also contains flag-rock, and is 550 to 600 feet in thickness ; while his 

 third grit is 300 to 450 feet, containing thin coal-seams and the fossi- 

 liferous shales ; his fourth division is the recognized fourth or Kinder- 

 Scout Grit. In cutting the "Wadsworth-Moor tunnel, connecting the 

 reservoir of AYiddop with the Castle-Carr conduit, 2550 yards in length, 

 through his second and third grit series (Third Grits ?) shales with 

 Goniatites, Ortlioceras, Modiola, Posidonomya, &c. occurred. Galena, 

 Marcasite, and an angular breccia were found in joints near a fault. 



A section (illustrating this paper) of the Halifax Rough Rock and 

 Flag Rock along the eastern edge of the Wheatley valley, is given in 

 vol. xiii. part vi. C. E. De R.

The bed was met with at 60 fathoms from the surface in sinking a 



shaft ; it is 19 feet thick, and lies horizontally. *' The rocks, as they 



approached it, were all altered by the heat ; and after they had passed 



through it, the^ coal at a depth of several fathoms showed traces of 



heat, although the intervening rocks ceased to show it." This spot is 



a mile from the whin-dyke. W. T.

 The author notes the distribution, origin, and structure of these 

 sandstone-blocks, especially in Wiltshire, and considers their drifting 

 to be coeval with the formation of the Brick-earth on the high Chalk-
