Faraday to John Frederick William Herschel   7 November 1825

Royal Institution | Novr. 7, 1825

My dear Sir

I send you the results of the analyses of some specimens of glass from the pots No. 1 and 3 of our experiment[.]

¹

The difference in the potash of the specimens from the top & bottom of the Pot No. 1. is very remarkable and is the reverse of that in the specimens from No. 3. Indeed taken altogether the results indicate very great irregularities in the pots[.]

I am dear Sir | Yours Very faithfully | M. Faraday

J.F.W. Herschell Esq | &c &c
