                                Four figures from issue 128 of Philosophical Transactions of the Royal Society, including (1) A hydraulic engine for pumping and spraying water and (2-4) geometric diagrams by Edmond Halley. 
Figure 1 illustrates ‘A description of an hydranlique engine, taken out of the register of the Royal Academy of the Sciences of Paris and inserted in the Journal des Scavans, 1675: Englished by the publisher, for the better examination of those that are skilfull in such engines here in England’ in Philosophical Transactions of the Royal Society, vol. 11, issue 128 (25 September 1676).
Figures 2-4 illustrate ‘Methodus directa & geometri-ca, cujus ope investigantur aphelia, eccentricirates, proportionesque orbium planetarum primariorum […]’ in Philosophical Transactions of the Royal Society, vol. 11, issue 128 (25 September 1676).
