    Description
    Rough sketches of how a single colon branched to the anuses of both the twins, and of their diaphragm. From a letter by the physician William Durston dated 28 October 1670 at Plymouth, to Timothy Clarke, reporting the dissection of a pair of conjoined twins born to Grace Bastard, a wife of a shoemaker 'of honest repute' and mother of five. In this letter Durston included a tape measure to indicate the size of the twin from head to toe. Another drawing done 'by a youth' at Plymouth, which accompanied this letter, has been moved to the Royal Society's Letter Book (LBO/4/095a). Durston's letter was read at the meeting of the Royal Society on 10 November 1670, and printed in Philosophical Transactions of the Royal Society, vol. 5, no. 65 (1670), without this sketch.

    In the previous year, Durston had reported to the Royal Society an abnormal swelling of a woman's breasts (EL/D1/11). In his letter, he similarly added a drawing and the tape-measure with which he had measured the breasts.
