CARRIE.--If a sufferer from anæmia, we think you could not do better than go for a month's treatment to Buxton, Derbyshire. Of course you should neither take the waters, nor use the baths, without medical advice, as your dietary should be prescribed as well as treatment by the waters. You will find much to interest you in the neighbourhood when able to walk, or drive, such as Haddon Hall, Chatsworth, and Old Hall; and a little diversion of the mind, and turning of the thoughts from personal ailments, will also tend to restoration. If you have a kodak, or have any taste for sketching, you will have plenty of subjects--objects for a walk. Should you prefer to go abroad, Royat near Clermont-Ferrand (France), which stands on an elevation of 1,400 feet above the sea, is a charming place; the waters of four springs--of mixed alkaline, gaseous, ferruginous, slightly arsenical and lithia waters--are to be had in the ancient Roman baths. Anæmia, lymphatic and other affections may find alleviation, if not a cure, in this beautiful mountainous locality. We have ourselves inspected these baths, and are likewise acquainted with Buxton and its neighbourhood. SONG-BIRD.--The instrument for regulating time in the performance of instrumental music, called the metronome, was invented by Johann Nepomuk Maelzel, a German machinist, in 1812, and patented in England in 1815. His younger brother was also an inventor, and produced two remarkable instruments, viz., one imitating an orchestra, called a panharmonicon and an automaton chess-player. A. B. C. inquires what the "Ptolemaic system" was, and who Ptolemæus was? He lived in the reigns of Adrian and Antoninus, a native of Alexandria, and was celebrated in those times as both an astronomer and a geographer. His system was quite erroneous, and was confuted by Copernicus, for he supposed the earth to be the centre of the universe. Do not confound him with Ptolemæus (called Ptolemy), and surnamed Lagus--as also Soter, on account of the assistance he gave to the people of Rhodes against their enemies. He was king of Egypt, and died 284 years B.C. This Ptolemæus I., though not an astronomer, was a man of learning, and laid the foundation of a library which became the most celebrated in the world. MARIAN.--The origin of the name Albion (by which the French elect by preference to call England) has its origin in mythology. For Albion was the reputed son of Neptune and Amphitrite, and was said to have come to Britain and established a kingdom, where he introduced the art of shipbuilding and the science of astrology.
