Interested Friend.—Gordon's Electricity and Magnetism, the last edition of Ganot's Physics, Deschand's Physics, and Guthrie's Electricity and Magnetism can be comprehended by the ordinary high-school boy. The school text-books on natural philosophy, as, for instance, Cooley's New Natural Philosophy, give much that is easily understood.
Humpty Dumpty.—The earliest posts for carrying letters between Brussels and Vienna were established in 1516 by Franz, Prince of Thurn und Taxis. His descendants enjoyed the monopoly until 1806, on the dissolution of the German Empire. The present Prince has a palace in Ratisbon, a very ancient city of Bavaria. It is sixty-nine miles north of Munich, on the right bank of the Danube. Its cathedral was founded in 1275, and completed in 1875. The abbey of St. Emmerau, the patron saint of the city, was enlarged by Charlemagne. In the rear of his palace the Prince of Thurn und Taxis can see a monument to Kepler, the astronomer, whose remains lie in the Protestant burial-ground.
E. T.—First Bishop of Liverpool.—The diocese of Liverpool was recently formed mainly out of Chester. Its bishop is the Rev. John Charles Ryle, D.D. He was nominated by Lord Beaconsfield, and was consecrated in 1880. He is known as the author of some excellent books of a devotional tendency, and as a commentator on the Gospels.
