The exciirsions of the year have been very fairly attended, and been pro- 

 ductive of much social pleasure and improvement to those who had the privilege 

 of taking part in them. Eastnor, Leintwardine and Kington were selected, as 

 affording points of great interest in their respective neighbourhoods, which have 

 been visited by several distinguished naturalists, who, since the year 1831, have 

 contributed so much to the illustration of the natural history of oiu: district, and 

 given it an importance, not merely local, but cosmical. 



The Eastnor meeting afforded us the gratification of the first joint meeting 

 with the members of the Cotteswold and Malvern Clubs, and together with the 

 enjoyment of the most exquisite scenery, upon a most charming day, the oppor- 

 tunity of associating and forming friendships with many already engaged in the 

 same exhilarating and ennobUng pursuit — the promotion of science and truth. 

 You will, with peculiar and melanchoh' pleasure, recollect, that on that occasion, 

 you had the high privilege, under the direction of our lamented friend Mr. Strickland, 

 to examine the structure of the south-western portion of the Malvern Hills and 

 Eastnor Park, aad were deeply interested and instructed by the lecture with which 

 he then favoured us ; in which he communicated those views of the changes of 

 surface, which modem science all but demonstrates must have taken place, since 

 the deposition of the sedimentary strata which flank that range on the western 

 side ; announcements which must have been regarded not less astounding than 

 novel, especially by those amongst us, whose minds had not been pre-engaged 

 by objects of geological research, and disciplined and inured by the spirit of 

 inductive philosophy. The centre of the Malvern chain was described as igneous ; 

 the successive sedimentary deposits, commencing with the equivalents of the 

 lower Silurian rocks of Sir Roderick Murchison, and continued to the Old Red 

 Sandstone, were enumerated. The effects of upheaval and denudation on the harder 

 and softer strata, producing the domes, ridges and valleys which make up the 

 more remarkable features of the nearer landscape from Malvern to Ledbury, 

 Woolhope, Cradley and Abberley pointed out ; the conditions assigned, under 

 which the sedimentary rocks, in many places mineralogically unaltered, were 

 deposited, upon beds of igneous matter already cooled down, in the bottom and 

 along the shore of an ancient sea, — their elevated, incUned, and in some, not 

 unfrequent cases, overturned position, in which they now remain, attributed
