Faraday to Richard Phillips   4 November 1825

Royal Institution | Nov 4th. 1825

Dear Phillips

I have made your zinc experiment and obtain from 81.5 gr of metallic zinc 122 c:i: of gas. This is a great deal too much but I fancy it accords with your result in being in excess. Of course you will search out the explanation the fact is too important to be passed by¹[.]

Yours Ever | M. Faraday
