My dear Sir,

We talk of starting for Italy in about a fortnight, viâ Paris, and being very anxious to see how photography prospers there, as well as other places, I should be particularly obliged if you w^d be so kind as to give me a line of introduction to M. Biot; ¹ who w^d no doubt enable me to prosecute any enquiries on the subject.

I thank you for the notice of the Calotype, which you were good enough to send me and have been ever since most anxious to see a more detailed account of the method if you have made it known, I sh^d be most grateful for any description, as it would save me much trouble, weight, and expence to substitute that method for the plates ² on which I hope to photographize Venice. The effect also I sh^d imagine is much more pictorial. I hope you saw the views of Margam ³ which I did for your cousin Talbot: they were done by an apparatus made by Davidson ⁴ of Edinburgh whose modifications are certainly improvements on Daguerre’s system.

I conclude you have before this seen my friend D^r Schafhaeutl, ⁵ who is in London, his method does not seem to have produced any practical results.

If you will add the smallest specimen of the Calotype, you will confer an additional favour on

yours truly obliged
Calvert R. Jones.
