Faraday to George Fisher   13 February 18241

Royal Institution, 13th February, 1824.

Dear Sir, - I send you an account of the air which you gave me for examination. There is a decided and constant difference between it and the air of this place2, which difference cannot depend on errors in the experiments. Perhaps you will be able to recollect the circumstances under which you collected it. If the mode by which it was obtained and preserved until it reached this place be unexceptionable, then the difference between the Polar Air and that of this climate will be established, at least to my satisfaction. - I am, Dear Sir, Your’s very truly, | (Signed) M. Faraday.

To Rev. George Fisher.
