From John Tyndall   23 October [1875]1

Royal Institution

23rd Oct.

My dear Darwin

I am very much obliged to you for your note.2

I wonder if I send two or three other tubes down whether Mr Henry (he lives near you I believe) would kindly place them somewhere in the open and observe them for me?3

Trust me, your friends were delighted to see you so joyful on Sunday, and it is a doubled pleasure to learn that you have not suffered from the dissipation.4

Ever yours | John Tyndall
