THis Horrox is the fame with him , that is the Author of 
that exGcIleoc TractiCalled Venus in Sole vifa, pubhfh*t by 
thQisLinous Johannes Hevelius together with his Mercurius in 
Sole vijus: who if he had not been foatch't away by an untime- 
ly death in the flower of his agej would certainly, by hisindu- 
ftry and exactnefs, which did accompany his great affection to 
Aftronoray, have very confiderably advanced that Science. 
Now we have only left us thefe imperfect Papers, digefted^not 
without great care and labour, by that Learned Mathematicia 
an Dr^Jobn Wallis > Wherein does occurr, 
Firfi^tht Keplerian Aftrooomy , afferted and promoted 5 
which this Author undertook^ after he had fpent much time, 
and taken great pains in acquainting himfelf with that of LanP- 
bergius^ which he at fif fl; embraced with fo much eagernefs and

and diligent Aftronomer of that time, he found, that neither 
theHypoihefes oiLanfbergius were confiftent among themfelves, 
nor his T^s^/^i- agreed with Obfervations exactly m^de, nor 
the Precepts of them were well demonftrated or could be ; 
whatever that mat! boafted of the wonderfull agreement of 
hisTables with the Obfervations of former times : All which 
errors having been found atlaftbyour Author himfelf, and 
wiihall the writings oils^pler^ and the Rudolphin Tables by hini 
fearch'c into, he faw caufe far to prefer them to the Lanshergr*' 
^Wjbecaufe grounded upon Hypothefes confonant toNature,aad 
well agreeing with the Heavens : though he found caufe by^ 
his accurate Obfervations to amend even thefe Tables^ yet 
without a neceflity of changing the Bypotheftu In which work 
when he was well engaged^he was cut off by death very youngs 
in the 23ih year of his age. His firft piece then, were his Dii- 
putations agaiuft the Aftronomy of Lanfbergiur. in which he 
clearly demonftratesj that the Hypothpfes of that Author do nei- 
ther agree with the iieavens nor among themfelves* Which, 
argument he carried on fo far, that having finiih't the/^^a^r firft
