From Michael Faraday   19 July, 1850

Upper Norwood,1 19 July, 1850.

Dear Sir,

I am very much obliged to you for the specimens of calcareous spar,2 and I shall very likely turn to the matter again some day soon. At present I am working upon another part of the great subject, and withal am out here for a little change of air and rest.

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

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