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.
