From Edward Sabine   Feb. 5t 1852

11. Old Burlington S^t | Feb. 5^t 1852

My dear Sir –

As you desired, your certificate for the R.S. was sent (with D^r Faradays signature affixed) to M^r Sylvester, six weeks ago,¹ from the RS., [day] post, addressed according to the direction in the RS.^ies list furnished by himself – After waiting a long while, a second letter was written to him to the same address, to which he has replied saying he knows nothing of the former letter – Had there been a mis-direction the letter would have been returned at the P.O. to the R.S. from which the certificate was dated. I conclude therefore that the letter was duly delivered but has been mislaid.²

I must plead this as a cause for troubling you once more for a statement of your works, as I have destroyed the one you formerly sent me³ – I will then obtain D^r Faradays signature again, together with M^r Huxley’s, M^r Grove’s, & M^r Gassiot’s (the 2 last named gentleman having expressed to me their wish to sign) and will sent it to you to forward to M^r Sylvester⁴ – & to return to me – It must be all done in the present month⁵ –

Sincerely yours | Edward Sabine.

D^r Tyndall;⁶
