Dear Sir,

I have received the enclosed invitation2 from Mrs Crosland.3 Unless I hear from you to the contrary I will meet you at the train which leaves London Bridge Station for Greenwich4 at 6.5 p.m.5 on Friday evening—Their house being nearer to Greenwich than to Blackheath.6

Very truly yours | Latimer Clark

Professor Tyndall.

P.S. | Should I by any possibility not be there, you will of course proceed on without me—you will easily find the house by a little enquiry. | LC

enclosed invitation: enclosure missing but the content can be inferred from a letter in Faraday’s correspondence in which Clark and Faraday were invited to visit the spiritualist, Camilla Crosland. See letter 3280, Clark to Faraday, 2 May 1857, Faraday Correspondence, pp. 228–9.
