John Tyndall to Faraday   2 June 1856

[Royal Institution embossed letterhead]

Dear Mr. Faraday

Sir Roderick Murchison I am informed has kindly expressed his readiness to grant us specimens from the Museum of Practical Geology provided an official application be made to him on the part of the managers. Fortunately a meeting occurs today, and I should feel obliged if you would bring the subject forward and obtain for me the application which Sir Roderick considers necessary¹.

Believe me | most truly yours | John Tyndall

2nd. June
