The commmiications and discussions on the safety-lamp ; on sudden out- 
bursts of fire-damp; on ventilation in mines; and on other subjects of a 
kindred nature, have, there is reason to believe, done good by awakening 
inquiry, and stimulating practical men to the exercise of habits of vigilant and 
accurate observation. 
No excursions were undertaken in the course of the past year. In some of 
the previous years there were occasionally pleasant and instructive rambles, 
by parties of the members, into localities presenting Geological features of an 
attractive kind ; and the Council thought it worthy of consideration 
whether a system of periodical excursions should not be arranged and put in 
practice, as one of the means for keeping up a lively interest in the Society, 
and for promoting the objects for which it was instituted. 
Another means, not yet adopted, has been suggested as likely to be pro- 
ducMve of good in the Society — the holding of evening meetings at the 
Museum, for the purpose of conversation, and for hearing short lectures ex- 
planatory of different groups of fossils in the collection. 
The Council urged the desirableness of considering the suggestion about 
making the Society more of a mining institute than a Geological Society — the 
improvement of muiing being one of the o])jects of the Society. 
Joseph Dickinson, E.G.S., was elected President. 
The routine business having been gone through — 
Mr. Edward Lacey exhibited two specimens of lead ore (galena) from a vein 
Avhich cuts, in nearly a vertical direction, through a coal at Axe Edge, Derby- 
shire. The coal is sixty yards above the limestone, and, where in contact with 
the lead, it is not charred nor altered in any way — clearly showing that the Itad 
Avas not introduced in a heated state. The vein of galena is about tliree 
inches in thickness, and is contamed in a fracture of the strata, or fault, which 
passes through the rocks above and below the seam of coal. It has been fol- 
lowed about fifteen yards above the coal, witliout presenting any indication of 
swelling out to a workable thickness ; but at present it has not been examined 
below the level of the coal on account of the accumulation of water in that 
direction. 
;Mr. Binney stated that he had described a similar vein found in Mr. Gis- 
borne's colliery, at Horwhich, near "VVhaley Bridge. The strata tliere and near 
Axe Edge were in the same geological position — namely, the liothdale series 
of coals. The bed of coal where the lead was found might be only sixty 
yards in horizontal distance from the limestone, but in vertical distance it 
would be near two thousand feet. The Whaley Bridge vein is described in 
his paper in the "Memoirs of the Literary and Philosophic Society of ^Nfau- 
chester."
