April 9

You see by the inclosed, written to me by the Iesuite Pardies ProffessrProfessor of yethe mathematicks in the Colledge of Clermont at Paris how nimble ytthat sort of men is to animadvert vpon new theories He being a person of some repute there, I doubt not but you will expedite an answer for him and ytthat in the same language, wherein he writeth.

Besides him, there is Monsieur Hugenius, ytthat hath also read and considered thesamethe same, who giueth me this note vpon it in his letter of April 9. st. n; videl.

Pour ce qui est Sela nouvelle Theorie de Monsieur Newton touchant la lumiere et les couleurs, elle me paroit fort ingenieuse; mais il faudra voir, si elle est compatible auec toutes les experiences. Cependant i'ay estè bien de trouuer ce qu'il escrit touchant l'effet des verres et miroirs en matiere de Lunettes, ou ie voy qu'il a remarquè comme moy, le defaut dela refraction des verres convexes objectifs à cause de l'inclinaison de leur deux surfaces.

yryour letter of march 30th was read before the R. Soc. on Thursday last, and they commanded me to thank you in their name for it, and for yryour care of removing the inconveniences ytthat may lye agstagainst yryour reflecting Telescope. Some tryal will be made, I hope, wthwith a prismatical Chrystal, in stead of yethe smal oval speculum And Mr Cock is at worke for one of 4 feet, yet wthwith both yethe speculums of medtal; wchwhich we long to see finisht, and ytthat we may try its performances.

The Transactions of March, wherein much is said of this Telescope of yrsyours, is now abroad, and I hope, your carrier will call this week at my house for one of you. It would be well, if your answer to Mr Hooks objections could be ready, to be inserted in the Transactions of this present month, wchwhich will goe to the presse about 10 or 12 days hence. If it cannot be ready time enough, I shall, if you permit me, put in the yryour two letters of march 26 and 30: they my of good matter, ytthat all appear in publick, what hath been suggested by yrselfyourself concerning yethe new Tots, most faithful servant

To his honored friend Mr Isaac Newton Professor of the Mathematicks in Trinity Colledge at
