_Mr. Lyte's New Process._--Although I presume it is none of your affair
what is said or done in "another place," will you kindly ask MR. LYTE for
me, if he will be so good as to explain the discrepancy which appears
between his "new processes," as given in the Journal of the Photographic
Society of Sept. 21, and "N. & Q." of Sept. 10? In the former he says, for
sensitizing, take (amongst other things) iodide of ammonia 60 grains: in
"N. & Q.," on the contrary, what would seem to be the same receipt, or
intended as the same, gives the quantity of this salt one fourth less, 45
grains--a vast difference. Again, in the developing solution the quantity
of formic acid is _double_ in your paper what it is in the journal.
I should not have trespassed on your space, but would have written to MR.
LYTE directly, except from the fear that some other unfortunate
practitioner may have stumbled over the same impediment as I have done, and
may not have had courage to make the inquiry.
