Object history

28 June 1711, 'Mr Waller’s paper of some Remarks on Dr Papins new way of improving Clockwork was read: In which he gave his reasons for dissenting from the Doctor’s Proposal of a continually circulating Fly or Balance the same way, objecting some uncertainties as he imagined in that way from the unequal opposition of the air, the increasing velocity of the said Balance, which he apprehended not sufficiently provided for, etc. He also shew’d some contrivances of the late Dr Hooke; and gave an explication of an Improvement of Clockwork, published by the said Dr Hooke in one of his quarto Tracts. Dr Papin desired this Paper to consider of the objections' (JBO/11/233).

12 July 1711, 'A paper of Mr Wallers in reply to Dr Papin’s Answer to his objections concerning the Improvement of Clockwork was read; which Dr Papin took with him to consider of' (JBO/11/237).
