                                At the meeting of the Royal Society on 21 November 1666,  ‘Mr. Hooke shewed the society another kind of pendulum, which being perpendicular and short, by counterpoising performed the part of a long one. The president was of opinion, that the circular pendulum, as far as he yet saw, was the best of all kinds, of which he had hitherto made trial’ (Birch 2:127).
