Short's lecture on the compensated pendulum, "... and it having been often asked, who was the inventor of it, I have therefore thought proper to draw up the following historical account of it: And as this account contains nothing but matters of fact, supported by the best authorities, I hope it will be acceptable to this Society, ..."
