some of the leading characters and the fossil contents of 
these ancient sea-bottoms, and the causes which would govern 
the presence or absence of the Molluscan and other marine 
population of ancient shore margins. Hye and hammer were 
now brought to bear upon the slabs of stone lying before them 
in the stacks. Here in a few minutes were detected the 
fractured rib of a Saurian, with numbers of great and small 
Cephalopoda, including many species of Ammonites, Nautili, 
and Belemnites; swarms of Terebratule and Rhynchonelle, and 
plentiful genera and species of Lamelli-branchiate Molluses 
and of univalve shells. All tell of warm seas surrounding 
islands on which grew Cycads, Zamias, and other plants of 
tropical or subtropical growth. Such were the lessons to be 
learnt from the embedded organisms of the Alderton quarry. 
Descending the hill to the village of Alderton the party 
found luncheon awaiting them at the Gardener’s Arms, from 
whence according to the published programme they should have 
proceeded to Gretton where an exposition of the geology of the 
beds was promised by Dr. Wricut; but the inexorable rain of 
that rainy season set in, and it was determined to postpone to 
a future day our visit to the quarries at Gretton and to return 
direct to Cheltenham where dinner was provided at the Plough 
Hotel, at the close of which a short account was communicated 
by the Rev. Dr. Suyrue of some fossil remains of a Plesiosaur 
which had been obtained by Mr. Lucy at Tate’s Hill, in the 
Middle Lias. These bones were to find a place in the Gloucester 
Museum, where I believe they have since been deposited. 
The fourth and last Field Meeting of the season was held on 
Thursday, 4th September. The members and their friends, to 
the number of thirty or more, assembled at the Dudbridge 
Railway Station, and proceeded to carry out the programme of 
the day, which included an inspection of the woollen cloth 
mill of Messrs. APPERLEY, Curtis, and Co., an examination of 
the geological strata of the Middle Lias at Dudbridge, a walk 
thence to Minchinhampton Common, passing over the Inferior 
Oolite, the Fuller’s Earth, and the Great Oolite, and the
