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

 the observations of Gascoigne and Crabtree, 1638-43 ; those made by Flam steed at Derby and the Tower, 1663-74, with the 

 sextant observations at Greenwich, 1676-89, spared from destruction with the edition of 171'2. 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 Beign, Tycho Brahe, the Landgrave of Hesse, 

 and Hevelius followed ; linally 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 A. M. Clerke. 



1351 LETTER concerning EARTHQUAKES, written in 1693, to a Gentleman then residing at 



Turin in Savoy, on the DESTRUCTION of CATANEA, and many other Cities, Towns, and Villages, 

 in Sicily, in 1692 ; with ivoodcut, 8vo. (pp. 24), seivn (RARE), 15* 1750 



This pamphlet is chiefly interesting from betraying the astounding ignorance of the Astronomer Royal in matters 

 chemical and meteorological. He explains that earthquakes are nothing else but explosions in the air, caused by the 

 filing of the ' nitrous and sulphureous particles' in the latter, and rejects the idea of underground causes as absurd.
