' Flamsteed's Historic Ccelestis, published in 1725, formed a new era in sidereal astronomy. The first volume comprised 

 the observations of Gascoigne and Crabtree, 1633-43 ; those made by Flamsteed at Derby and the Tower, 1663-74, with the 

 sextant observations at Greenwich, 1676-89, spared from destruction with the edition of 1712. The second contained his 

 observations with the mural arc, 1689-1720. The third opened with a disquisition entitled ' Prolegomena to the Catalogue ', 

 on the progress of astronomy from the earliest ages, chiefly valuable for the description, with which it terminated, of the 

 Greenwich instruments and methods ; the catalogues of Ptolemy, Ulugh Beigh, Tycho Brahe, the Landgrave of Hesse, 

 and Hevelius followed ; finally came the ' BRITISH CATALOGUE ' of 2,935 stars observed at Greenwich, to which Halley's 

 southern stars were appended . . . His ' British Catalogue ' is styled by Baily ' one of the proudest productions of the 

 Royal Observatory at Greenwich '. Its importance is due to its being the first collection of the kind made with the 

 telescope and clock '. Miss Agnes M. Clerke.

'The chief source of information regarding Flamsteed. The materials for this valuable work were derived largely from 

 a mass of Flamsteed's MS. books and papers, purchased by the Board of Longitude for 100, in 1 771, which lay in disorder 

 at the Royal Observatory until Baily explored them . . . The first part contains Flamsteed's History of his own Life and 

 Labours, compiled from original MSS. in his own handwriting ... An appendix contains a variety of illustrative docu- 

 ments, besides Flamsteed's voluminous correspondence with Sharp, Newton, Wren, Halley, Wallis, Arbuthnot, Sir Jonas 

 Moore, and others. The second part comprises the British Catalogue, corrected and enlarged to include 3,130 stars by 

 Baily. An elaborate introduction is prefixed, and a supplement, added in 1837, gives Baily's replies to criticisms of the 

 foregoing publication.' Miss Agnes M. Clerke.
