Dear Sir

I venture to intrude again upon your well occupied time – and explain our object. It is a complete illustration ¹ of the results of Photography. For example a picture on paper prepared with Nitrate of Silver only ² – with the Chloride &c leading to your Calotype ³ – and specimens of all the chemicals employed in the production – The same with the Daguerreotype ^<4> & Sir John Herschel’s processes ⁴ If therefore you could furnish the Museum with one good Negative Camera View – and a positive copy printed which we should only inscribe as presented by the inventor of the Calotype we should be greatly indebted to you.

I am Dear Sir Yours very truly
Robert Hunt

H Fox Talbot Esq^r
