dated a Theory of that Planet ; and of the Moons Libration, He 
has attempted alfo (and perhaps by this time performed) a Sek- 
nographj by meafure, what we have yet of that kind being rather 
fiSiures^ than accurate furveys or map of ihtMoon : To this pur- 
jDofe he contrived a Lunar globe, reprefenting not only the Mou.i^ 
tains znd Va/lejs in folid work, but the fcveral degrees ofw/ntenefi 
and blacknej^ on the (urface, which if turned to the light, (hews 
all the menfirual fhafes of the Moon^ with the feverai appearances 
that arife from the pjadovps of the Hills and Vales. 
28. He has made Maps of the Pleiades^ and other Telefcopial 
Jiats, and propofed ways to folve the great Quefiion concerning 
the earths reft or motion by fome fmall fiars about the North pok^ 
to be feen only in large and well made Telefcopes : To which In- 
Jlrument he has added many forts of Pete's^ fcrews^ and Apertures-, 
to take in more or lefs ligbt, by opening and (liutting like the pu- 
pil of the eje, according as the Obferver thinks fit ; and has im- 
proved the manufallure of grinding good ^/^j^j. He has alfo 
made two Telefcopes to open with a joynt after the manner of a 
fe^icr^ whereby difiances may be taken to half minutes, and no 
differences found in the fame objervation often repeated, the In- 
firument not being lyable to any prejudice by warping or luxation. 
He has contrived and hung Quadrants, Sextants, and Padii, much 
better than heretofore., by which A/fronojnical Obfervations m^y be 
made more accurate and eafie. Of all which ingenious and ufe- 
ful In^'-e^rions, there are much more full and elegant relations, in 
the raoft accurate //i/'^orj/ of the Pojal Society : However, they 
being moft, if not all of them found owl here, or at leaft whil'ft 
.their Author was Afironomy Projeffor in this Vniverfity^ 1 could not 
but mention them with relation to this place, as I fliallfome other 
matters which ow their invention to the fame worthy perfon. 
29. And thefe are all the modern advancements in Agronomical 
matters I can at prefent think of, onely a late invention of one 
i?. Holland, a teacher of Mathematicks in this City for many years, 
who has fliewed us a way to get the Angle of Parallax of a Comet 
or other Phdenomenon at two objervatious to be taken in any one 
ftationor placeof the earthy and thereby the diftance from the 
earth : whereof no more, there being a fliort account of the 
whole contrivance fet forth by himfelf, and printed at Oxford.
