I. An Attempt to prove the MOtlOJSfof the EARWfrom Oh- 
jervations , made hyKohtn Hook Fellow of the R. Society, 
London in 4*. printed for J. Marty n at the Bell in St. Pauls 
Church yard, 16 74. 
^T^He Ingenious Author of this Attempt , having confi- 
X derd with himfelf, that the grand Controverfie about 
thG Mot/m of the Earth rmdiins yet undetermin'd, and find- 
ing, there was no other means left for human Induftry to decide 
it but by obfer^ving, whether there be any fenfible Parallax of 
the Earths Orb amongfl: the Fixt Stars ; did thereupon refolve 
to employ himfelf in making fome Obfervations concerning fo 
important a point,in Aftronomy. AryJ, after he had examined 
the ways and inftrumerits for all manner of Aftronomical Ob- 
fervatioris, hitherto made ufe of, and confider'dof the incon- 
veniences and imperfeftions of them ; and having alfo duely 
weighed the great accuratenefs and certainty, that this Ob- 
fervation of the Earths Fara/laxtGquired : He next contrived 
a way of making Obfervations, that might be free from all the 
former inconveniences and exceptions, and, as near as might 
be, fortified againft any other that might' be invented or 
railed againfl: it. This way he gives an Account of in this 
prefent Traff^ which is^ To obferve by thepafling of fome 
confiderable Star near the Zenith of fome place, whe- 
ther fuch aStardothnot at one time of the year pafs nearer to 
tiiat Zenith y and another, farther from it 5 thus reafoning with 
himfelf, That, if the Earth doth move in an Orb about the Sun, 
and that this Orb hath any fenfible Parallax amongft the Fixt 
Stars, this mufrnecelTarily happen, efpecially to thofe Fixt 
Stars, which are neareft the Pole of theEcliptique* 
Accordingly he affirms to have aftually made four Obfervati- 
ons, in this Traft defcribed 5 by which, he faith, *tis manifeft, 
that there is a fenfible Parallax of the Earths Orb to the Fixt 
Star in the Dragons head, and confequently a Confirmation of
