our own time, for the boulder underlies the raised beach of Barn- 

 staple Bay. And as that beach contains shells of the same species as 

 those now living on the coast, which are not dwarfed (as they would 

 have been in an icy sea), it is inferred that the boulder must have 

 been deposited long before the beach above it.

BiNNEY, E. W., F.E.S. (Jan. 21st, 1873), exhibited drawings of 

 petioles of specimens allied to Anaclioropteris Decaisnii of Eenault, 

 of oval form, from the Lower Coal-measures of the Foot Mine, near 

 Oldham, Lancashire. Also a plant from the Lower Brooksbottom 

 seam of coal, allied to the genus Anacliopteris. 



Plant, John, F.Gr.S. (Jan. 27th, p. 113.) " Description of 

 Minerals and Ores from Venezuela," Collected by Mr. J. M. Spence. 

 Gold quartz, galena, copper ores, iron ores, coal, and graphite. 



Williamson, Prof. W. C. (Feb. 4th), stated that the second plant 

 described above was not a new genus, but the fruit of Asterophyllites. 



Brockbank, William, F.G.S. (Feb. 18th). "Notes on supposed 

 Glacial Action in the Deposition of Haematite Iron Ores in the Fur- 

 ness District." Haematite occurs (1) filling hollows in limestone, 

 capped by glacial drift ; and (2) in veins in the limestone, and in 

 irregular pockets. The author considers the iron ore to have been 

 transferred by the action of an ice- sheet from the place of its original 

 occurrence, and redeposited with the glacial drift in the crevices and 

 hollows of the limestone (1). Giving a section at Dalton-in-Furness 

 to explain his views. • 



Dawkins, W. Boyd, F.E.S. " The Eesults of the Settle Cave 

 Exploration." (p. 61.) Eomano-Celtic enamelled jewelry and 

 implements, in the upper bed of the Victoria Cave, of the era pre- 

 ceding the conquest of West Yorkshire and Mid-Lancashire by the 

 Northumbrians. Beneath this stratum lay six feet of angular stones 

 with neolithic flint flakes. Below occurred a stiff clay, believed to 

 be of glacial origin, nearly thirty feet thick, resting on an ossiferous 

 bed, with remains of cave bear, mammoth, reindeer, etc. 



BiNNEY, E. W. (March 4th, p. 72), states that the plant believed 

 by himself to belong to a new genus, alluded to by Prof. Williamson 

 as belonging to the genus Asterophyllites, was described by Prof. 

 Eenault, of Cluny, as a Splienophyllum (Comptes Bendus for 1870). 



Dawkins, W. Boyd, F.E.S. (March 18th, p. 83.) " Observa- 

 tions on the rate at which Stalagmite is being accumulated in the 

 Ingleborough Cave." Three holes were bored, and gauges of brass 

 wire gilt inserted in the base of the stalagmite, 13th March, 1873. 

 The possible age of the "jockey cap" stalagmite was calculated in 

 1845 by Prof. Phillips, from observations of Mr. James Farrar, at 259 

 years. Mr. Dawkins found the rate of increase to be 0-2946 inch a 

 year, and that the whole of the stalagmite and stalactites of the 

 Ingleborough Caves may not date further back than the time of 

 Edward the Third.
