Dear Sir,

I write this note to say that if it is convenient to you it will give me great pleasure to spend a couple of days with you this week. We returned last night from Ely ¹ where I spent two very agreeable days with the Dean ² after the ceremony of the Institution was over.

As I am collecting materials for an Article on the Calotype and Daguerreotype for an Article which will appear in the Edin Review ³ for Oct^r next, I am very anxious that you should provide me with any historical or personal details which have not yet appeared respecting the Calotype, and which I know would be very interesting. Bessel ⁴ put into my hands a Proof of an Article which will appear in Poggendorffs ⁵ next N^o (The Annalen &c) by Prof^r Moser ⁶ containing the most extraordinary discovery of Latent light, exhibiting itself in the formation of Pictures on clean polished Silver placed very near to any picture or body that has absorbed light inequally. Such bodies give negative & positive pictures in succession!! We had a most curious discussion on the subject on the last day of the Association. ⁷

I cannot find in the ordinary Railway Guide any acc^t of the times or ways of travelling along the Birmingham and Gloucester Railway, tho’ a plan of it is given in the Maps of these Books.

I am Dear Sir, Ever Most Truly y^rs
D Brewster
