_Minuteness of Detail on Paper._--Being fond of antiquarian studies,
and having learned from "N. & Q." the value of photography to the
archæologist, I have serious thoughts of taking up the practice of
the art. Before doing so, however, I am anxious to learn how far that
minuteness of detail which I so much prize, and which is of such value to
the antiquary, is to be obtained by any of the processes on paper. I have
seen some specimens produced by collodion which certainly exhibit that
quality in an eminent degree. Is anything approaching to such minuteness
attainable by any of the Talbotype processes?
