thick, there being also a similar bed immediately above the 

 firestone which forms the roof of the quarry, and a similar 

 layer of hard rock divides the hearthstone above into two beds ; 

 it is always called "roofiing-stoue," and a stone somewhat 

 resembling it is fouud in the Coal measures, and is there also 

 known as "roofing-stone." The fossil most frequently found 

 in the firestone in this district is a fossil sponge "Siphonia." 



EwHUKST Mill. — August 26. (Conductor, Mr. A. C. 

 Sterry). The members met on this occasion at Gomshall 

 Station, and proceeded by field-paths and lanes to the village 

 of Peaslake, after passing through which a path was taken up 

 the valley leading direct to Ewhurst Mill. Here the profusion 

 of flowers of the Heather, &c., such as is rarely seen, made 

 the sides of the hill in some places to be one blaze of purple. 

 Continuing the gi'eater part of the way through a Pine forest, 

 we aiTived at the top of Conyhurst Hill, opposite the Mill, at 

 noon, just as the sun shining on the sea beyond Shoreham 

 Gap makes it from this point distinctly visible. The gorse 

 on the sides of the hill had been burnt, leaving only the dead 

 stems, on which were a quantity of a curious fungus {Hy- 

 jioxylon concentricum), sections of which were shown by Dr. 

 Bossey at the Annual Meeting. The return was not by the 

 prettiest route, through taking a wrong road, and a drenching 

 rain did not improve matters ; but all were nearly dried again 

 by the sun before reaching Black Heath. The lane leading 

 from Black Heath to Chilworth Station is cut through the 

 sand, giving a fine view of the layers of ironstone occurring 

 in the Lower Greensand ; they are here curved and twisted 

 in every direction, and so much so that it is almost impossible 

 to conceive how they can have been formed. The return 

 journey from Chilworth Station ended a pleasant, though 

 somewhat uneventful day. Amongst the flowers and plants 

 met with may be mentioned — Siuw anyustifolmw , in the bog 

 near Gomshall Station ; and Asplenium Adiantuin-nvjrum , 

 found in abundance on the way home before reaching the 

 bottom of the hill. 



BLETcmNGLEY. — September 9. (Conductor, Mr. W. H. 

 Tyndall). The members of the Club met at 2.30 to walk to
