Faraday to Henry Briggs   20 March 1846¹

R Institution | 20 Mar 1846

Dear Sir

All I can say to your enquiries respecting the possibility of fusing Nitric Acid & Ammonia is that I was long ago fully impressed with the importance of doing so & tried my best with cold[,] pressure[,] platina & every other way I could think of but without success. Still I do not think the problem irresolvable & very likely may hereafter resume it (if not settled by others) though I do not know at present on what tack I should forward[.]

Ever Truly Yours | M. Faraday
