Fulton observes that there is, properly speaking, no general title page. The work is covered by the half title (A1a) prefixed to the three parts which each have an independent title. The plate with 7 figures (illustrated above) is not called for by Fulton or other bibliographers. It appears as one of two plates in New Experiments and Observations touching Cold (London, 1665) [Fulton 70].

Apart from the deteriorated binding, this is a good, unmarked copy of Boyle's first scientific work. The generalisation which carried Boyle's name to posterity, that the volume occupied by a gas is the reciprocal of its pressure, did not appear in the first edition of 1660, but was propounded in the second edition as a result of Linus's attack upon the deductions which Boyle had made concerning the air's weight. The first English air pumps were not actually designed by Boyle, but by Robert Hooke, who had been taken on as a paid assistant in about 1655.
