    Description
    A figure illustrating the kilning stage from John Flamsteed's paper on the malting process at Derby, which was originally given to his patron, Sir Jonas Moore. Moore mentioned the paper in a meeting of the Royal Society on 17 July 1679.

    The drawing, and the drawing on the previous page (MS/92/304/e), are part of a collection of letters 'for the improvement of husbandry and trade', which were 'Described for R[ichard] T[ownley] Esq. by J[ohn] F[lamsteed], January 1682/3.

    Another version of this figure can be found at Cl.P/10iii/33/006.

    Included in a copy of a manuscript, 'Memoires of Naturall Remarques in the county of Wiltshire' by John Aubrey, transcribed by B. G. Cramer, Clerk to the Royal Society.
    Transcription
    Our kills being all of them foursquare, we begin at any side, and with the broud-shovel cast up all the green Malt on it, into two heaps in the opposite Corners, the dryest next to the Hair-cloth, into the middle space, betwixt them; as it we began at the side e, in the upper Figure, we throw all the green Malt into two heaps in the opposite corners a& b. but the little dry next the Hair-cloth, betwixt them to c; then having shaken up the Hair-cloth, so that no loose Corns may stick to it, and again laid it down very strait, we removed the freen heap to the opposite Corners d; c; in the under Figure, but the little middle heap, with the dry under the other two, the shakings of the Cloth after they are removed to the space betwixt them, e, then again composing the Hair-cloth, the first cast down the two green Heaps all over it of an even thickness, and then the dry Heap all over them; thus the greenest is turned to the bottom, and the dry lyes on the top. Afterwards the Malster rakes it all over with a Wooden Rak to leave it every where of as even a thickness as possibly he can.

    Object history
    At the meeting of the Royal Society on 17 July 1679, ‘Sir Jonas Moore related, that Mr. Flamstead had formerly given him a description of the way and process of making Derby malt, and promised to look it out, and bring it to the Society. He also added, that the people of that town had a way of cooling their ale very quickly, so as it blinketh it so, as they called it, that it grows clear and fit to drink presently’ (Birch 3:496).

    This manuscript is a transcript of Aubrey's original manuscript (1685). It was transcribed by B. G. Cramer, Clerk to the Royal Society, at the behest of the Society in 1690-91. At page 67 is inserted a map of a navigable passage from Bristol to London, engraved by Thomas Jenner in 1668, with the arms of the borough. Six leaves of additional matter are inserted at page 276, and four more at page 304.
