"Stranger, Beneath this _cone_, in _unconsecrated_ ground, A friend to the liberties of mankind directed His body to be inurned." The expression in each case, respecting the place of his interment, seems scarcely strong enough for us to conclude it was a _windmill_. Perhaps J. H. M. will kindly favour me with the authority for his statement. Nares has made the following note on the epitaph at the bottom of the page: "I heard John Wilkes, after praising Baskerville, add, 'But he was a terrible infidel; he used to shock me!'" R. W. ELLIOT. Clifton. * * * * * PHOTOGRAPHIC CORRESPONDENCE. [At the suggestion of several correspondents we have reprinted from _The Athenæum_ of the 22nd Nov. 1851, the article detailing the new process by Mr. Muller referred to by the Rev. MR. SISSON in our last Number.] _Mr. Muller's Process._--"The following photographic process has been communicated to us by Mr. C. J. Muller, from Patna in the East Indies. We have submitted it to an experienced photographer; and he informs us that it offers many advantages over the Talbotype or the Catalissotype of Dr. Woods, which it somewhat resembles; that it is easy in all its manipulatory details, and certain in its results. We give Mr. Muller's own words-- "'A solution of hydriodate of iron is made in the proportion of eight or ten grains of iodide of iron to one ounce of water. This solution I prepare in the ordinary way with iodine, iron-turnings, and water.--The ordinary paper employed in photography is dressed on one side with a solution of nitrate of lead (fifteen grains of the salt to an ounce of water). When dry, this paper is iodized either by immersing it completely in the solution of the hydriodate of iron, or by floating the leaded surface on the solution. It is removed after the lapse of a minute or two, and lightly dried with blotting-paper. This paper now contains iodide of lead and protonitrate of iron. While still moist, it is rendered sensitive by a solution of nitrate of silver (one hundred grains to the ounce) and placed in the camera. After an exposure of the duration generally required for Talbot's paper, it may be removed to a dark room. If the image is not already out, it will be found speedily to appear in great strength and with beautiful sharpness _without any farther application_. The yellow tinge of the lights may be removed by a little hyposulphite of soda, though simple washing in water seems to be sufficient to fix the picture. The nitrate of lead nay be omitted; and plain paper only, treated with the solution of the hydriodate of iron, and acetic acid may be used with the nitrate of silver, which renders it more sensitive. The lead, however, imparts a peculiar colorific effect. The red tinge brought about by the lead may be changed to a black one by the use of a dilute solution of sulphate of iron:--by which, indeed, the
