I presume from the length of time that has elapsed you have again laid down the project of etching from Photography on Steel <1> in the early part of last Spring it occured [sic] to me that your gelatine would act in all respects – over an aquatint ground – as it would on a bare steel and I had prepared some solution of both hopeing [sic] to give you an agreable [sic] surprise. when your plates came up with a ground so like aquatint that I feared you were before hand with me in the idea, and expecting to see a farther progress as well as conscious that I should have much to learn that you had already acquired, I waited rather than acted I am certain however that the principle can be carried out, but do not see my way to the profit. Should I at any future time fancy that most desirable contingency appear attainable how far might you be inclined to facilitate the matter? by a gift of a licence to operate for my sole benefit
I have from the first, lent you my disinterested thoughts, in help of a principle of natures own, the difficulties of which you have more means and greater leisure and infinitely more experience than myself to overcome, yet all seems at a stand

1. Barclay started corresponding with WHFT in 1852 and carried on at least until 1858, so his suggestions could apply to either photographic engraving or photoglyphic engraving. See Doc. No: 06795, Doc. No: 06817 and Doc. No: 07735.
