and exceedingly acceptable addition of the kind President to the 

 agrements of the day. 



After lunch Mr. Symonds, with his usual enthusiasm, and with 

 the confidence of one who has known and studied every inch of 

 the ground which he was about to describe, gave an eloquent 

 resumi of the geology of the district. Facing the Malvern range, 

 ■which, running north and south, stood out of the haze in an 

 extended serrated line, he commenced by taking for granted that 

 he was addressing men who knew something of the technicalities 

 of geology, and to whom an explanation of the terms as he pro- 

 ceeded was unnecessary. That fine range of hills in front of them, 

 he said, was the key to the whole of the geology of the district — 

 they were the representatives of the oldest rocks on the earth's 

 surface. All had heard of the Laurentian rocks of Canada, the 

 most ancient sedimentary rocks in the world. The equivalents of 

 these rocks had been found in the Isle of Lewis, on the west coast 

 of Scotland, in Sutherland and Eoss, and he believed they were 

 now looking upon old Laurentian deposits in those metamorphosed 

 rocks forming the Malvern range before them. Associated with 

 these rocks were ancient lava beds traversing them as dykes, these 

 being representatives of the oldest volcanic rocks in England. In 

 these were some evidences of the cause of that metamorphism and 

 disturbance so evident on all sides. On their flanks rested quart- 

 zites, which may be certain altered representatives of the Cambrian 

 rocka, and along the South Malvern were the Lower Silurian rocks 

 also here and there altered by the volcanic influences alluded to. 

 Along the Malvern flanks, hundreds of square miles in Wales, and 

 vast areas in Sweden are represented by, as it were in comparison, 

 the sharp edge of a knife. Allusion was here made to the result 

 of Dr. Holl's labours in working out the geology and mineralogy 

 of the Malvern rocks, and Mr. Symonds proceeded to describe how 

 after the deposits of the Lower Silurians, and about the period of 

 the upper Lingula beds, there was an outburst of volcanic matter 

 again along the line of the Malvems, which, as in Snowdonia, 

 poured its ashes into the surrounding sea. In the Malvern country 

 the site of the Llandeilo and Caradoc formations is occupied by 

 trap, no Caradoc proper being found in this country. At this time
