Dr Sir
I enclose another copy of the Specifn – Mr Reade’s 1 process being so different from that mine I am told it is scarcely necessary for me to adduce evidence 2 of its comparative inefficiency. Therefore I will not trouble You to make any Expts 3 on that hand.
As I wrote to you this morning 4 on the subject of following closely ye words of my Specifictn 5 in any expts on photogrc pictures you make with a view of testing the accuracy, I will only add that I understand the defendt & his witnesses 6 mean to attack its accuracy and say it contains serious errors. But after the most careful scrutiny I can find none. It was the best process known at the time, it has been improved since both by myself and others, but there is no error in it.
I remain Dr Sir Yours vy Truly
H. F. Talbot
