During the day the President described the various beds, 
particularly directing attention to the Pea Grit and the well- 
known Coral Bed. Mr Wethered exhibited some photographs 
of the Pea Grit, reduced to thin sections for microscopic 
examination, and which showed that the granules contained 
the nuclei of organisms. 
The party then ascended the hill to the Camp and, not- 
withstanding a gale of wind blowing at the time, Mr Witts 
gave an excellent account of the Camp which, he said, formed 
one of a series along the Cotteswolds, and was remarkable for 
the well-preserved rampart and gateway. The latter was so 
built that an enemy entering would be obliged to turn to the 
left, and so expose himself to the defenders. The ramparts 
appeared to be made up of rock material which had been burnt, 
but he was not prepared to offer any explanation of this. Mr 
Bellows made some remarks on Roman Camps generally, and 
the members then walked to Birdlip, looking at some quarries 
on the way, and dined at the George Hotel. 
The fourth and last meeting, fixed for Eastnor, had to be 
changed, and took place on the 10th August, when sections on 
the new line of railway in course of construction from Kemble 
Junction to Tetbury were carefully inspected. A brief look at 
some of the beds at Kemble, it will be recollected, was made in 
June last, before proceeding to Edgeworth. The members had 
the advantage of the presence of Professor Etheridge, F.R.S., 
and were under the guidance of Professor Harker, who took 
them along the line to Jackment’s bottom, which is on the 
Ackman Street Roman Road from Cirencester to Bath. The 
route showed some interesting exposures of the Great Oolite, 
which is estimated to be 100 feet in thickness, in the middle of 
which occurs a remarkable bed of stone called the Dagham. 
At the request of the President, Professor Etheridge gave a 
description of the bed, and also those examined during the 
walk along the line. The day was very hot, and on arriving at 
Jackment’s Bottom the members gladly availed of the kindly 
forethought of Mr M. Biddulph, M.P., who had provided some 
very acceptable refreshments, Here carriages were taken,
