Extract

At Messrs. Hills' brickyard, ½ mile north-north-west of Purton Station and about 4 miles north-west of Swindon, Wiltshire, a large pit in Upper Oxford Clay (Lower Oxfordian) is worked by modern methods to a depth of over 60 feet. Ammonites are for the most part preserved as white powdery or flaky impressions, as in the Jordan Cliff Clay at Weymouth, and their collection involves technical difficulty. For help with the collecting and measuring I am indebted to Messrs. C. W. and E. V. Wright, and for every facility at the pit to Mr. Hill.
