POMPEY inquires whether the modern Romans wear the same picturesque flowing robes at the present day that were worn at the time of Christ? There is no difference between their dress and that of the rest of Europe. As to the history of Rome and its ancient buildings and churches, there is a new book called _Mediæval and Ecclesiastical Rome_, published by Black. The first volume might add something to the information you say you have obtained in _The Story of the Nations_ series, _The Last Days of Pompeii_, and a few others--which you do not specify. The book we name is reputed to be an excellent, and very exhaustive guide-book, and the best yet written. JOICE M.--We recommend you to get a little book on _Leather Work_, by Rosa Baughan (Gill: 17, Strand, W.C.). This will give you all the direction you can require. JANIE.--The term "Black Letter," as used in reference to printing, only means what we call "Old English" type, which is often used on visiting cards. But old books, such as that interesting historical chronicle of current events, by Stowe, is all printed in that type, and in the spelling of that century. It is known elsewhere as the "Flemish, or German type." Ancient illuminated missals, such as those exhibited in the British Museum, are in "Black Letter," and most beautifully written by pen in this style of lettering. LILY.--Nothing is known of Jannes and Jambres, named by St. Paul in 2 Timothy iii. 8, beyond the fact that they existed, and withstood Moses before Pharaoh--statements of divine authority. But, according to very ancient tradition, they were two sons of the rebel, Balaam--who died fighting against Israel--and, furthermore, that no real miracle was wrought by them, but that they practised mere jugglery. The name "Jerusalem," means "the City of Peace," though its history shows the name very inapplicable. It was the site of the stronghold Jebus, taken from the native tribe, and made that of the Israelitish capital. The ancient name was revived by David, for a cuneiform tablet found at Tel-el-Amarna (in 1890), written centuries before the Hebrew conquest, appears to refer to that place under the form of Urusalem. Our authority is that of Robert Anderson, whose interesting work on _Extinct Civilisation_ is worth your study. AMY.--You seem to have overlooked our many advertisements of the _Asile des Billodes_, C. de Neuchâtel. If you look through old numbers of the "G.O.P.," you will find them in the answers to correspondents. Some of our earliest writers for this magazine have been taking out stamps for the institution for many years past, every year, in large quantities. GEORGIE.--The colour of the Red Sea is due to a thin brick-dust layer of infusoria, which is slightly tinged with an orange hue. The water placed in a white glass bottle is changed to a deep violet, but the surface of the sea shows a brilliant rose colour.
