MR. WOODWARD will, I apprehend, readily agree that these sentences come from no one connected with the Roman Church. And they are quoted in the hope that Protestants will cease to cite this supposed Bologna Council as any valid or genuine testimony to Romish proceedings and sentiments. NOVUS. [Footnote 3: See an account of him in McCrie's _Hist. of the Reformation in Italy_, pp. 77. 115. &c.] * * * * * PHOTOGRAPHIC CORRESPONDENCE. _Mounting Positives._--If the print and the mounting paper, or Bristol board, are _both_ made equally damp, and the back of the picture covered with thin paste, they adhere without any unevenness; and if the print is on the fine Canson's paper, the appearance is that of an India proof. They should remain until _perfectly dry_ in a press. H. W. DIAMOND. _Mounting of Photographs, and Difficulties in the Wax-paper Process._--May I request a little additional information from your correspondent SELEUCUS, Vol. ix., p. 310., respecting the mounting of photographs? Does he mean merely the painting the edges, or the smearing of the photograph all over its back with the Indian-rubber glue, prior to sticking the proof on the cardboard? If the former, which I apprehend he does, SELEUCUS will necessarily have the unsightly appearance of the picture's buckling up in the middle on the board being bent forward and backward in different directions? May I take the liberty of asking him in what respect the plan proposed is superior to that of painting over the edges with mucilage of gum arabic, containing a little brown sugar to prevent its cracking, allowing it to dry, and prior to the placing it on the card, slightly moistening it; a plan superior to that of putting it on the board at first, as all risk of a portion of the gum oozing out at the edges is thereby avoided. I have long been in the habit of mounting prints and photographs in a way which prevents their buckling, keeps the paper underneath quite smooth, and in other respects is so perfect, that it positively defies the distinguishing of the picture from the paper on which it is mounted. I am not certain that my plan is applicable to the mounting on card-board, as it cannot be wetted and stretched, thinking it useless to make use of such a costly material when a tolerably thick drawing-paper will more than serve the same purpose at a very considerably less expense, seeing that the photograph thus mounted bears a much closer resemblance {382} to that of a good and costly print. A good plain or tinted sheet of drawing-paper, 30 inches by 22, may be obtained at the artists' colour shops for sixpence, sufficiently large for two drawings, 9 inches by 11, allowing a sufficient margin.
