It is curious to observe how matters of history appear and disappear as it were. "The mighty Tottipottimoy," says Hudibras (part ii. cant. ii. l. 421.),—on which the Rev. Dr. Nash has this note: "I don't know whether this is a real name or only an imitation of North-American phraseology; the appellation of an individual, or a title of office:"—Tottipottimoy was king of the warlike and powerful Parnunkies, and was defeated and slain by the Virginians, commanded by Colonel Hill, in the action from which Bloody Run takes its name.
There is a curious passage in the Westover MSS. concerning William Penn, of which Mr. Macaulay should have a copy, unless one has been already sent to him.

Cyanide of Potassium.—It may be interesting to our photographic friends to know that cyanide of potassium is capable of replacing hyposulphite of soda in all collodion processes. If used of the strength of five grains to one ounce of water, no danger need be apprehended from it. Its merits are cleanliness, quickness of operation, and the minute quantity of water required for washing the picture fixed therewith.

Mode of exciting Calotype Paper.—I forgot inserting this plan of exciting in my paper: it is very clean and convenient, simple and sure. Obtain a piece of plate glass, two or three inches larger than your paper, level it on a table with a few bits of wood, pour on it your exciting mixture (say aceto-nitrate and gallic acid, solution of each 20 minims, distilled water 1 ounce), and spread it evenly over with a scrap of blotting-paper. Float your paper two minutes, remove and blot off; this ensures perfect evenness, especially if the paper is large. You may thus excite half a dozen papers with little more trouble than one.
