My dear Sir
I can shew you pictures on Mica which I have used instead of glass for Collodion – Paper has been proposed instead of the glass in some of the numbers of the Photographic Society’s <3> Journal. If you wish me to make any other exact experiments besides the one with the positive process, let me know. My assistant <4> is to try your ordinary (original Calotype process. If he fails I shall try it myself, if he succeeds you can have no more triumphant proof of its success & correctness.
I shall be in Town on Saturday next or perhaps on Friday afternoon & shall take the earliest opportunity of calling on your Solicitor <5>.
Believe me, always Yours very truly

2. Talbot claimed the collodion process as an extension of his patent calotype process, rather than a new invention. He hoped to prove this in court by showing that the pyrogallic acid used in the collodion process had the same effect as the gallic acid used in the calotype process [see Doc. No: 07067].
3. This had begun in 1847 as the Photographic Club. It subsequently became the Royal Photographic Society.
