"This being the 73rd year since my Almanack first appeared to the world, and having for several years presented you with observations that have come to pass to the admiration of many, I have likewise presented you with several hieroglyphics," &c. EDWARD F. RIMBAULT. That such a personage really did exist there can be little doubt, Bromley (in _Engraved Portraits, &c._) gives 1657 as the date of his birth, and says that there was a portrait of him by Drapentier _ad vivum_. Lysons mentions him as one of the remarkable men who, at different periods, resided at Lambeth, and says that his house was in Calcott's Alley, High Street, then called Back Lane, where he seems to have enlightened his generation in the threefold capacity of astrologer, physician, and schoolmaster. J. C. B. * * * * * Miscellaneous. NOTES ON BOOKS, SALES, CATALOGUES, ETC. Professor De Morgan has just furnished a new contribution to _L' Art de verifier les Dates_, in the shape of a small but most useful and practical book, entitled _The Book of Almanacks, with an Index of Reference, by which the Almanack may be found for every year, whether in the Old Style or New, from any Epoch Ancient or Modern up to_ A. D. 2000. _With means of finding the Day of any New or Full Moon from_ B. C. 2000 _to_ A. D. 2000. An example will show, better even than this ample title-page, the great utility of this work to the historical enquirer. Walter Scott, speaking of the battle of Bannockburn, which was fought on the day of St. John the Baptist, June 24, 1314, says, "It was a night of lovely June, High rose in cloudless blue the moon." Now, should the reader be desirous of testing the accuracy of this statement, (and how many statements have ere this been tested by the fact of the moon's age!), he turns to Professor De Morgan's Index, which at 1314 gives Epact 3., Dominical Letter F., Number of Almanack 17. Turning to this almanack, he finds that the 24th June was on a Monday; from the Introduction (p. xiii.) and a very easy calculation, he learns that the full moon of June, 1314, would be on the 27th, or within a day, and from a more exact method (at p. xiv.), that the full moon was within two hours of nine A.M., on the 28th. So that Sir Walter was correct, there being more than half moon on the night of which he was speaking. Such an instance as the one cited will show how valuable the _Book of Almanacks_ must prove to all historical students, and what a ready test it furnishes as to accuracy of dates, &c. It must take its place on every shelf beside Sir H. Nicolas' _Chronology of History_.
