Athenĉum <1> London
I am much obliged by Your letter. <2> I expect to be in Edinburgh Friday or Saturday In reply to your question about the steel engravings, <3> they are entirely the product of Photography aided by Chemical action, and have not been touched in any way by an artistic hand Some of them look as if the shadows were effected by the cross cutting of a gravers tool but it is really the shadow of a piece of black crape or rather of two pieces laid diagonally one over the other.
Believe me Yours very Truly
