Dear Sir,
I have received the packet of impressions from plates engraved by your newly invented process and have shewn them to my partners. We all think the wonderfully beautiful, and that such an invention must prove a valuable acquisition to the arts. I have no great faith in the well working of Limited Liability Companies nevertheless such a company if it comprised some earnest workers might succeed. I am sorry that I cannot give the subject more attention at present but as I leave tomorrow I am overwhelmed with matters pressing upon me. I return the specimens by rail because it is better that they should not be seen until you have taken more steps in bringing your invention before the public.
I have instructed Mr. Howlitt to take a magnified positive of one of my best lunar negatives and to send it to you for your acceptance - and if your leisure permits of your making an engraved plate as you propose to do I shall highly prize it. The impressions should represent the Moon as seen in an inverted telescope. [diagram of moon]
I shall be away about two months and shall feel pleasure if I can forward your views on my return.
I am dear sir yours very truly
