Faraday to John Tyndall   19 July 1850

Upper Norwood, | 19 July, 1850.

Dear Sir,

I am very much obliged to you for the specimens of calcareous spar, and I shall very likely turn to the matter again some day soon1. At present I am working upon another part of the great subject2, and withal am out here for a little change of air and rest3.

I am, my dear Sir, | Very truly yours, | M. Faraday.

J. Tyndall Esq. | &c. &c. &c.


Address: To J.T. | Spring Bank | Over Darwen | Lancashire

Tyndall, Diary, 7 August 1850, 4: 427-8 recollected his meeting with Faraday of which this letter was clearly an outcome. Faraday and Tyndall differed from each other in their views on diamagnetism but at this meeting Faraday, according to Tyndall, said that it was of “No matter ... you differ not as a partisan but because your convictions compel you”. Also quoted in Eve and Creasey (1945), 32.
