B. T. A. _The line_ "England, with all thy faults I love thee still," _is
by Cowper_ (The Task, book ii.).
REV. J. J. _We fear some injustice was done--unintentionally, but fear also
that it is now too late to remedy it._
INQUIRER (Birmingham). _Some of our correspondents have met with great
success from Mr. Crookes' process; but we are bound to say that it has not
been universal._
G. W. E. _recommends that in immersing a collodion plate it should first be
inserted horizontally, and then transversely in the nitrate of silver bath,
as a sure means of avoiding spots_.
_He is informed that if the edges of his glass are roughed, it will greatly
tend to the adhesion of the collodion. The nitrate of silver bath, used for
exciting collodion plates, is not available for exciting albumenized paper
or any other purpose._
H. C. C. _1. The addition of cyanide of potassium to the sensitive
collodion not only prevents its decomposition, but appears to add to its
general good qualities. 2. Protosulphate of iron mixed with your nitrate
bath is quite fatal. 3. Good pictures are constantly taken when the
temperature is below sixty; though there is no doubt all chemical action is
quicker in warm weather._
B. (Manchester). _See_ "N. & Q.," No. 205, _October 1, 1853_.
W. BEATSON. _There are difficulties in the way of such an exchange of

believe the Photographic Society, with the aid of an energetic Council,
have been unable to effect this, even to a limited extent._
