the process given by_ MR. POLLOCK; _we have seen most satisfactory pictures
produced by it._

R. H. CHATTOCK (Solihull). _The "freckled" appearance which you mention in
your positives in all probability depends upon the action of the light upon
the silver, which still remains in your proof. We have often found it to be
the case when old hyposulphite of soda is used, and when the strength of
the bath is becoming weak and doubtful. It is certainly a safe process to
soak the picture in clean water for an hour or two,_ the light being
excluded _previous to the immersion into the hypo.; and the water
extracting a large portion of the solutions remaining on the paper, the
after application of the hypo. need not be so long continued, whereby the
tone of the picture is not so much lowered. Your own observation, that a
piece of Whatman's paper being merely divided, and one point exhibiting the
defects and the other not, at once negatives the idea that the size in the
paper has been affected._

_The_ Index _to our_ SEVENTH VOLUME _will be ready on Saturday next, the
