25. But how far he came fliort of what he pretended, was 
fo plainly and modeftly made appear by the Reverend Bifiop^ in 
a Book which heentituled, Inquifitio in Ifmaelis Bullialdi Afirono- 
tnidi: Fhilolaic<£ fundamenta. Edit. Oxonii, 1653. ^^^^ ^^e ingeni- 
ous BullialdH6 himfelf, fent him a Letter thanks, and recogni- ^ 
tion of his errors. Where alfo he further (hews, that although 
Bullialdm 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 ^/'riori, their true or ^t/'- 
pearing motions: That yet there were methods by which it might- 
be done, whereof he propounded tvpo in the fame Boo4, and de- 
monftratedthem, which afterwards applying to all zhe primary 
Flamts^ he fee forth both Elliptical and Circular Aftronomy^ ftiew- 
mghow t\\e Phi^nomena^ 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 Aflronomical mdtters^ who, 
amoagfl: many other excellent performances in that Science to be 
met with in our Englip P hilofophical Tranfa^ions \ has Hiewed us 
a d\ie^'m6. geometrical method ^or finding the Aphelions-, Excentri- 
cities^ and proportions of the Orbs of the primary Planets^ with- 
out fuppofing the equality of the angle of motion at the other Fo- 
cu^ of the Planets Ellipfis^ which has been hitherto always done 
amongft Afironomers ' ; From whom I dare promife yet further 
improvements^ he being lately gon to the Ijle of St. Uden^ for the 
more ad vantagious profecution of his Aftronomical fludies ; from 
whofe Jolitary ohfervations there, and comparati^fe ones with Mr. 
Flamfted's 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 Christopher 
Wren^ late Profeffor here : who before any thing of Hugeniws ap- 
peared on that [ubje5i^ from his conftant obfervations of baturn^
