                                Mary and Martha Waterman, daughters of John and Mary Waterman of Fisherton Anger, near Salisbury, were born conjoined on 26 October 1664 and died two days later. A report with a schematic figure (EL/B1/82/003) was forwarded by Robert Boyle to Henry Oldenburg, and was read at the meeting on 2 November 1664. Further information was sought and received on 9 November 1664 from the physician William Hann, who delivered a description of his dissection of the twins and further figures.

                                At the meeting of the Royal Society on 2 November 1664, ‘There was read an extract of a letter written to the secretary by Mr. Boyle, giving an account of a monstrous birth, lately born at Fisherton near Salisbury, and promising to communicate what observables might farther happen concerning it’ (Birch 4:480).
