The 14'^. 17^^. id^^. and 17'^ are Letters which paf- 
fed between Mr. Flamjted and the Author ; dilcourf- 
ing the reafons why the one chooleth to make ufe of Te- 
leJcopick^Si^hts, and the other of Tlain Sights : with fome 
Obfervations imparted fram each toother, and difqui- 
fitioas thereupon. Mr. Flamjied excufeth fome doubts

plain Sights s the Author afcribes them rather to his trufl- 
ing to feveral Scholars of his, to make many of his Ob- 
fervations 'y fome of whom were either not fo skill- 
ful, or not fo careful!, as fome others were ; either in 
making' the Obfervations, or noting them down, or 
computing from them ; On which, account it is (ho.
