han obliged for the kindness
thereby conferred.

My wax-paper negative, much to my disappointment, occasionally exhibits,
more or less, a speckled appearance by transmitted light, which frequently,
in deep painting, impresses the positive with an unsightly spotted
character, somewhat similar to that of a bad lithograph taken from a
worn-out stone. I should wish my wax-paper negative to be similar in
appearance to that of a good calotype one, or to show by transmitted light,
as my vexatious specimen does when viewed on its right side by reflected
light. As the most lucid description must fall far short of a sight of the
article itself, I purpose enclosing you a specimen of my failure, a portion
of one of the negatives in question. Would immersion, instead of floating
on the gallo-nitrate solution, remedy the evil? Or should the impressed
sheet be entirely immersed in the developing fluid in place of being
floated? And if in the affirmative, of what strength should it be? I have
thus far tried both plans in vain.

[The defects described by our correspondent are so frequent with
manipulators in the wax-paper process, and which DR. MANSELL has called
so aptly a "gravelly appearance," that we shall be glad to receive
communications from those of our numerous correspondents who are so
fortunate as to avoid it.]

_The New Waxed-paper, or Ceroleine Process._--The following process,
communicated to the French paper _Cosmos_ by M. Stephane Geoffroy, and
copied into _La Lumiere,_ appears to possess many of the advantages of the
wax-paper, while it gets rid of those blemishes of which so many complain.
I have therefore thought it deserving the attention of English
photographers, and so send a translation of it to '"N. & Q." As I have
preserved the French measures--the _litre_ and the _gramme_--I may remind
those who think proper to repeat M. Geoffroy's experiments, that the former
is equal to about 2 pints and 2 ounces of our measure; and that the
_gramme_ is equal to 15.438 grains, nearly 15-1/2.

ANON.

I send you a complete description of a method for either wet or dry paper,
which has many advantages over that of Mr. Le Gray.

I assure you it is excellent; and its results are always produced in a
manner so easy, so simple, and so certain, that I think I am doing great
service to photographers in publishing it.
