S {sic}

I hope M^r Linus's Friends will acquiesce in y^e late tryall of y^e Exp^t in dep|b|ait, for y^e procurement of w^ch & for sending them notice of y^e event, I return you my hearty thanks, as I have reason. I perceive I went upon a wrong supposition in what I wrote concerning M^r Boyles Exp^t. The Papers in yo^r hand I have no present need of: You may send them at yo^r best leisure. Sometime this Sommer it's possible I may make use of them, if I can but get some time to write y^e other discourse about y^e colo{illeg}|u|rs of y^e Prism w^ch I have long intended. S^r I am

Yo^r humble & obliged

Servant

Is. Newton.
