C. _Will this Correspondent favour us with his address in exchange
for that of_ NEWBURY, _which we have, and who wishes to correspond with
him?_
J. O. _May we insert the interesting Reply sent by this Correspondent, or
is it his wish that we should forward it?_
W. S. F. _will find an interesting article on the loss of Gray's original
MS. from La Grande Chartreuse, in our_ First Volume, p. 416.
J. M. G. _Is not the translation of_ The Ode, _spoken of in the article
alluded to as being by James Hay Beattie, the one respecting which our
Querist inquires?_
F. M. (A Maltese). 1. _We should recommend our Correspondent to make his
gun cotton with the nitrate of potash and sulphuric acid, as originally
recommended in_ "N. & Q.," _taking care that they are both thoroughly
incorporated before the addition of the cotton. Much vexation often occurs
in consequence of the various strengths of nitric acid. But the gun cotton
can now be procured at some of the photographic houses quite as reasonably
as it can be prepared._ 2. _Acetic acid is added to the pyrogallic acid to
prevent its too rapid decomposition, and to facilitate the more easy
flowing of the fluid over the plate. But the more acetic acid is used, the
more slow will be the development._ 3. _Is not the cracking of the albumen
the result of the climate of Malta?_
F. (Manchester). _We do not think that you can do better than adopt
strictly the mode of obtaining positives recommended by_ MR. POLLOCK, _and
which we printed some time since; or that pursued by_ DR. DIAMOND, _which
we have in type, but have been compelled to postpone until next week._
A. B. C. _Having ourselves practised the_ Paper Process, _according to the
directions given in our first Number for the present year (with the
correction of using the gallic acid, which, as stated in a subsequent
Number, was by accident omitted), we would advise our Correspondent to
adhere _strictly_ to those rules rather than any other with which we have
since become acquainted. We are of opinion that sufficient care is very
rarely used in the preparation of the iodized paper, and upon which all
future success must depend._
_A few complete sets of_ "NOTES AND QUERIES," Vols. i. _to_ vii., _price
Three Guineas and a Half, may now be had; for which early application is
desirable._
"NOTES AND QUERIES" _is published at noon on Friday, so that the Country
Booksellers may receive Copies in that night's parcels, and deliver
