    Description
    Map of a coal mine showing where thermometers (C and K) were placed by Richard Towneley in part of his letter to Henry Oldenburg dated 20 September 1672. It was presented to the meeting of the Royal Society on 6 November 1672, when the figure was ordered to be enlarged by the amanuensis. The paper appears to have been read on 27 November 1672, though there is no record of it in the Journal Book.

    Oldenburg recorded on this paper that the first part of the letter was probably mislaid when this part was handed over to the amanuensis to enlarge.

    Copies of this image can be found in LBO/5/372 and LBC/5/409.
