I. — Cotswold Field Club. —The 32nd anniversary meeting of the 
Cotswold Club, under the presidency of Sir W. Y. Guise, Bart., 
F.L.S., etc., took place on April 14, 1877. It was also the 19th 
annual meeting presided over by its president. About thirty 
members attended to hear the address and to, arrange for the 
meetings and general business of tbe coming season. The club tlien 
adjourned to tbe School of Art to hear Mr. W. C.Lucy’s paper on “ Tbe 
Extension of tbe Boulder-clay and Drift over tbe Cotswold Bange.” 
Mr. Lucy referred to a former paper read before tbe Club in 1869, 
in whicb be stated that he had not found Northern Drift pebbles at 
a higher elevation tban 750 feet, confirming the observations made 
many years ago by Prof. Hüll, wben surveying tbe district. Mr. 
Lucy also mentioned that be was not aware of tbe presence of 
Boulder-clay, unless some clay whicb had been found in tbe partings 
of a quarry at Woodebester, witb a small quantity of pebbles im- 
bedded in it. should prove to be it. Tbe special object of his paper 
seemed to be tbe discovery of tbe same highly silicified clay in 
various parts of the Cotswolds, including ihe highest point of Cleeve 
Cloud. This clay be had had analyzed by Prof. Church and Mr. 
Embrey, and tbe result, as will be seen by tbe following table, sbowed 
so marked a resemblance in the per-centage of silica as to leave 
no doubt that it was all derived from tbe same source ; and from 
tbe Northern Drift pebbles being found witb it, Mr. Lucy classed k 
as belonging to tbe Boulder-clay period, indicating that tbe wbole 
of tbe Cotswold ränge was submerged during that time. Mr. Lucy 
also traced the same clay in a gravel-pit in the vale at Frampton, 
whicb clay be believed was once on the higher ground, and from 
tbe weathering of tbe friable Oolitic rocks, had been brougbt into 
its present position.

Mr. Lucy further pointed out tbe undoubted presence of ice action, 
as sbown at Limbury, and at Aston Magna, and otber parts of tbe 
Upper Cotswolds, and explained that striations were. not found in 
tbe Gloucester area owing to tbe soft character of tbe Oolitic rocks. 
We cannot follow bim in tbe account he gave of tbe grooving of tbe 
Lias in the valleys upon whicb some of the gravels rest, nor tbe 
very difficult and complicated second Boulder-clay to whicb be 
referred.
