i%6 The Statural Hijlory 



Uties geometrically, and making Tables; calling his work Aslrono- 

 miam PhilAaicam. 



25. But how far he came fhort of what he pretended, was 

 fo plainly and modeftly made appear by the Reverend Bifiop, in 

 a Book which heentituled, Inquifitio in Ifmaelis Bullialdi Ajlrono- 

 mi<e Philolaic* fundamenta. Edit. Oxonii, 1653. tnat tne ingeni- 

 ous Bullialdu* himfelf, Cent him a Letter of thanks, and recogni- 

 tion of his errors. Where alfo he further (hews, that although 

 Bullialdws had not, and Kepler thought no man could , rightly 

 calculate the firft inequalities according to the rules of Geometry, 

 i. e. out of the known middle motions of the Planets (or true 

 places of the Aphelions') accuratly find a priori, their true or ap- 

 pearing motions: That yet there were methods by which it might- 

 be done, whereof he propounded two in the fame Book-, and de- 

 monftratedthem, which afterwards applying to all the primary 

 Planets, he fet forth both Elliptical and Circular Aftronomy, fhew- 

 inghow the Phenomena, according to both Hypothefes, might be 

 geometrically made out, which he called his Aftronomia Geometrica, 

 Edit. Londini, An. 1656. 



26. The Elliptical Hypothecs has received yet further advance- 

 ment from Mr. Edmund Rally of Queens College Oxon. a young man, 

 for his years of prodigious (kill in Agronomical matters, who, 

 amongft many other excellent performances in that Science to be 

 met with in our Englijh PhilofophicalTranfaclions % has (hewed us 

 a direft. and geometrical method for finding the Aphelions-, Excentri- 

 cities, 2nd proportions of the Orbs of the primary Planets, with- 

 out fuppofingthe equality of the angle of motion at the other Fo- 

 cus of the Planets Ellipfts, which has been hitherto always done 

 amongft Aftronomers 1 : From whom I dare promife yet further 

 improvements, he being lately gon to the Ifle of St. Helen, for the 

 more advantagious profecution of his Aftronomical ftudies ; from 

 whofe folitary obfervations there, and comparative ones with Mr. 

 Flamfted\ here, Aftronomy no queftion will receive confiderable 

 advancements. 



27. To which may be added feveral other improvements this 

 Science has received from that incomparable perfon Sir Chriflopher 

 Wren, late Profefjor here : who before any thing of Hugenius ap- 

 peared onthnfubjeft, from his conftant obfervations of Saturn,
