Faraday to Lyon Playfair   25 May 1858

Royal Institution | May 25th, 1858.

My dear Playfair,- That such a question should arise! I cannot give - i.e. volunteer - a certificate for circulation; it is against my rule; but if any one asks me whether you are able to expound the truths of experimental science to a large number of persons in a clear, logical, audible, and, to me, satisfactory manner, I should have no need to consider, but must from my own experience say “Yes” at once. Anyone concerned in the matter may write to me, or you may show them this note, which contains what would be my answer¹.

Ever truly yours, | M. Faraday
