li'/ed in oor days we could have given no kfs, to one who iii all 
probability was a great Improver atleaft, if not tht Inventor of 
i\\zzxy{d\x\ Mathematical Ir/firument^ fmce by QaliUii6 and others 
called the Telefcope ; of which admirable Invention perhaps Ox- 
ford may juflly boaft, and for it expeft to be celebrated to all 
fteritji. Which affertion if made good with ail perfpiciiity and 
clearnefs, without wrefting any words or begging favorable con- 
ftrui^ion, I think I need not to doubt but on all hands 'twill be 
granted, that the ohfervations here made as they were new and fre- 
quent^ fo to the vulgar and ignorant, they mull needs be terrible

fed thefeglafes in Celefdal Ohfervations^ is altogether as evident 
from the fame Book-, where he proceeds in thefe words. De vifione
