William Hyde Wollaston to Faraday   27 June 1828

1 Dorset Street | Manchr Square | Friday 27 June 28.

Dear Sir

I called, some days since, at the Royal Institution &, not finding you at home left for you with the porter the bottom of the crucible containing the lead in hopes that you would examine how little had been lost.

I now send the glass which has been slit & polished for examination but have retained a thin slice from the bottom for the purpose of shewing to Mr Pellatt¹ how very little even of this glass is contaminated thereby[.]

Your much obliged | W.H. Wollaston.

Address: M Faraday Esq | R. Institution
