In cutting drains for the Oxford sewage distribution on Mynchery Farm, Sandford, Oxon.. near the Thames, in 1879, four potters' kilns and other Roman remains were discovered, and systematic exploration of the site was then undertaken by the late George Rolleston, F.R.S., Linacre Professor of Physiology, assisted in the work by our Fellow Mr. Heneage Cocks, who studied anatomy under Professor Rolleston, and by the sewage engineers Messrs. Cobbold Brothers. Unfortunately the Professor died before fully working out the results of the exploration, and only a brief summary appears in the appendix to his Scientific Papers and Addresses (1884), ii, 937.
