Dear Sir
I have just received your favor of Friday and herewith send the Positive Photograph from which the negative sent was done I have the negative on glass from which the positive now sent was done and I may as well send it along with another with stronger lines which I will take the first opportunity of making, as they will require to be packed in wood and sent pr Railway
I think I can promise negatives of the kind you describe both perfectly opaque in the black & clear in the white
I am Sir Yours truly
William McCraw
P.S. I think your method of printing through the glass without giving a blurred impression would occasionally be extremely useful if it was known generally
