182 NOTES—ORIGINAL AND SELECTED. belongs to that series of Oolitic rocks known as the Oxford Clay. Fragments of this rock occur plentifully in the Boulder Clay of Essex. The large block from which the font was sculptured presents some difficulties, as one rarely meets with erratics of that size. Moreover, in the porch of the church other large blocks of the same material occur. It may be, seeing that most of the material of which the church is built is local, that several large boulders occurred in contiguity in the neighbourhood. The parent rock is distant over sixty miles. The sculptor has had his difficulty with this refractory block, and has very neatly pieced in a section where there was without doubt a flaw, and the wonder is that he has succeeded at all in getting such smooth surfaces. The rock is crammed with fossils of which Gryphaea incurva is the most conspicuous. That the work was done by a local man we think there can be no doubt, for there are irregularities which would scarcely have appeared with the professional man, and neither would the professional worker have chosen such a block to work upon. Its age, taken in connection with the blocks in the porch, would appear to be contemporary with the building of the church.—John French, Waltham Cross. MISCELLANEOUS. Bread made from Turnips in Essex in 1693.—In the Philosophical Transactions for the year 1694, I find1 printed a curious letter from Samuel Dale (1659 ?—1738), friend and executor of Ray, addressed to Mr. John Houghton, then Sec- retary of the Royal Society. It described a method of making a kind of bread or cake from turnips, which was practised by poor people in Essex at the end of the seventeenth century. This letter is to-day entirely forgotten, and it seems, therefore, worth while to reprint it in the pages of the Essex Naturalist. The letter (which is described as an "abstract" merely) runs as follows :— Braintree, Dec. 6, 1693. Sir,—The dearness of corn hath occasioned many poor people to set then wits, as it were, on tenter-hooks and to try many ways and methods of making bread for the sustenance of their families, as, in some places, of pease and, frequently, of barley. So, with us, they have lately got a way of making it with turneps ; which, not only for the novelty thereof, but also because it may be of 1 Philos. Trans., xvii., p. 970 (1694).
