I thought the negative executed by your Assistant 1 Very good – My impression is, that you should produce it & say who made it & how it was made, which you would be allowed to do, if your assistant were in Court 2 and prepared to give similar evidence if called upon – Thus his imperfect English would be no detriment.
Pray lend me Griffins Scientific Miscellany. 1841. 3 Mr Hunt 4 now says that previous to 1841 viz. in 1840 he was acquainted with the process of developing the invisible image, or a Similar one to mine. It will be important to show from his own testimony that such process was new to him in 1841.
Can you send me the book to the Athenæum? 5
Yours truly
