_Waxed-paper Pictures._--Will your correspondents or yourself do me the
favour to say, how such beautiful pictures have been produced and exhibited
by Mr. Fenton and others by the waxed-paper medium, if that process be so
bad and defective? When I have followed it, and exercised consistent
patience, I have ever produced pleasing and faithful results. That when
parties do not themselves prepare, it becomes expensive, I am willing to
admit; but I am inclined to attribute many failures to the uncertain heat
of hot irons, which _must_ vary; and I make this fact known to you as the
result of my own observation on many sheets: added to which, defective
manipulation, or impure chemicals, must not be allowed to do away with its
having much merit.
