Faraday to John Frederick William Herschel   8 November 1852

Royal Institution | 8 Novr. 1852

My dear Herschell

I send you a letter I have received from M. Wolf1 as he especially desires. After you have seen it I will send it if you approve according to his wish to the Royal Society or to the Astronomical2 if you think it better[.]

Ever faithfully Yours | M. Faraday


Endorsed by Herschel: Period of solar spots 9 Periods in 100 y or 11 y 11 Min to Min

The commencement 1800, &c. of each century is a minimum

See note 8, letter 2586 for evidence that letter 2586 was sent to the Royal Society. There is no indication one way or the other that it was sent to the Royal Astronomical Society. The topic was raised there but based on Wolf (1852d).
