Once grant the probability of this being the case, and we have no further difficulty in understanding why _Comus_ should be stitched up "with the late Rd. poems," or Wotton be left in ignorance of the author's name. Lawes tells us in the dedication to _Comus_, that it was "not openly acknowledged by the author;" and the publisher would naturally keep the secret: but why Rouse or Robert Randolph should do so, appears to me inexplicable. I hope soon to have access to some public libraries, and also to return to this very interesting question again. Meanwhile, may I beg the forbearance of your more learned correspondents? RT.

Newton's Process._--Having been requested by several friends to give them a statement of my mode of proceeding with reference to the calotypic art, and as I am of opinion that we ought to assist each other as much as possible in the pursuit of this important branch of photography, I beg therefore to offer the following for insertion in your "N. & Q.," if you should deem them worth your acceptance. _To iodize the Paper._--1st. Brush your paper over with muriate of barytes (half an ounce, dissolved in nearly a wine-bottle of distilled water): lay it flat to dry. 2nd. Dissolve sixty grains of nitrate of silver in about an ounce of distilled water. Ditto sixty grains of iodide of potassium in another bottle with the like quantity of water. Mix them together and shake well: let it subside: pour off the water, and then add _hot_ water: shake it well: let subside: pour off the water, and then add three ounces of distilled water, and afterwards as much iodide of potassium as will redissolve the iodide of silver. Brush your previously prepared paper well with this, and let dry; then place them in water, one by one, for about one hour and a half or two hours, _constantly agitating the water_. As many as a dozen pieces may be put into the water, one after the other, taking care that there are no air-bubbles: take them out, and pin to the edge of a board at one corner. When dry they will be ready for exciting for the camera by the following process: (These are supposed to be in six 1-ounce bottles with glass stoppers.)
