Faraday to W.H. Ince   5 May 1843¹

R Institution | 5 May 1843

My dear Sir

Crystallizations are very common on panes of glass especially in London & manufacturing towns. Sulphate of Ammonia - Mur Ammonia - Carbonates & salts of the fixed alkalies &c &c occur some being derived from the atmosphere some from the glass acted on - some from the human beings &c about. They are very well known to chemists & have been often described though my memory does not say when but I think in the Old Mechanics Journal &c. If you speak on the matter do not use my name for we chemists consider the matter so common & common place that we should be rather ashamed of putting it forth as a thing not known[.]

Of autographs I have none at present - plenty of applicants[.]

Ever Truly Yours | M. Faraday

W.H. Ince Esq | &c &c &c
