Fig. A1. Time line of significant events with relevance to Derham’s paper on sound. Newton’s prediction of what we know call the isothermal speed of sound was given in the 1st edition of Principia; it was not until Laplace’s third paper that theory for the proper “adiabatic” sound speed was published. Tyndall relied on von Humboldt’s hypothesis, which Tyndall called flocculence, in his interpretation of sound transmission; whereas, Henry advocated Stokes’ hypothesis of sound refrac- tion. Derham’s earlier work on clocks positioned him well for accurate measure- ment of sound speed but, when the prize for a ship-board chronometer was announced through the Longitude Act of 1714, he and many others shifted their focus to astronomical observations.
