                                3 February 1664, ‘Mr. Hooke’s account both of the weight of the air in a large receiver 119 English wine pints, and of the proportion of the weight of the air to weight of the water, was read; and the latter was ordered to be repeated. It was ordered, that whoever made report of an experiment but once made, should repeat it, for the sake of more accuracy and certainty’ (Birch 1:377). 
10 February 1664, ‘The experiment concerning the weight of air, and the proportion of the weight of air to that of water, was repeated; of which Mr. Hooke was directed to give an account in writing at the meeting’ (Birch 1:379).
