June 19th 1672.


Having been in Bedfordshire since my last to you, I at my returne to Cambridge I received yor letter conteining the Philosophicall Transaction{s} for ye last Month inclosed: For wch I returne you many thanks. At prsent I am removed into Lincolnshire & if you {illeg}|ha|ve occasion to write to me before ye 28th day of this Month I pray direct yor letter to me at Mris Smith's house in|at| Woolstrope in Coulsterworth-Parish neare Grantham in Lincolnshire. And for greater security you may further assigne it to be left at Post-Witham to be sent as abov according to direction. In ye answer to Sr R. Morays Experimts there was reflexion printed twice for refraction: wch in the next Transactions may be noted amongst ye errata. The particular places I know not how to direct you to, not haveing ye Book by me, but by the sense you will easily find them. I desire you would not yet print any thing more concerning the Theory of light before i{illeg}|t| hath been more fully weighed. And begging pardon for ye hast in wch I write, I subscribe my selfe
