Description
Diagram in William Molyneux's letter to Edmund Halley dated 8 April 1686, discussing Halley's construction to illustrate the latter's rule of determining angles of shooting with a mortar piece. Molyneux notifies Halley that George Tollet had devised a rule for calculating the angles on seeing Halley's diagram. The letter was read to the Royal Society on 21 April 1686.
The figure is copied from the original letter at EL/M1/94/003. Another copy is at LBC/10/379. Tollet's discussion of this problem may be found in Cl.P/1/20 and elsewhere in the Royal Society Archives.
