Tti Mr. Crahtrits fecond Letter, which is of Oiibher 
30. 1640; after a very clear Demonftration that the- 
Solar Spots are not Planets at a Diftance from the Sun^ 
but fomething adhering to, or very near the Sun’s Bo- 
dy ; and alfo after a no lefs clear Demonftration of the 
Errors of Lansherges Hipparchian Diagram, his Lunar 
Farallax, his Dod:rine of Edipfes, and indeed bis whole 
Lunar Afironomy, together with divers other curious 
Matters, too many to be fpecified : after this, I fay. Mr. 
Crabtrie faith thus, Something I am fare you rrere telling 
me concernin'T a way of obferving the F laces of the Planets 
ly your Glajfes. But 1 have not a little lamented that my 
Time cut me fo fhort, when 1 was with you, that I could not 
more fully ruminate and digeft thofe flrange Inventions

your Ajiflancei and that {what in me lies) I may help you 
to remember when and wherein your Inventions and Obferva- . 
tions vcilL be of mofl ufe. I Jhould alfo defire you to inform 
me what Bignefs of a Quadrant you . conceive, to he large 
enough for Obfervation with your Devices. For I ant e’re 
long going to Wigan, iz Miles from hence^ where much 
Brafs is cafl 5 and then / could fee whether I could procure 
fuch an one cafl. Toutold me as I remember) you doubted 
not in time to be. able to make Obfervations to Seconds. J can- 
not but admire it and yet, by what 1 faw^ believe it i hut long
