Charles Wheatstone to Faraday   c. November 18441

20 Conduit Street | Monday

My dear Sir

You will find the most ample account of Thilorier’s2 experiments in the 60th vol of the “Annales de Chimie” p 427-434 and in “L’Institute” vol 3 (1835) pp 321 3313. If you have not these books at hand you can have them by sending over for them. You will find also some interesting experiments of Pouillet’s4 on thermo-electric currents produced by means of solidified carbonic acid in the “Comptes rendus” No 14, 18375. If what this author states in his Elemens de Physique be correct you should be able to render manganese magnetic at 20° or 25° below centigrade zero6.

Yours very truly | C. Wheatstone


Address: Dr. Faraday
