ead, and who possesses a taste for reading, can find entertainment at home, without being tempted to repair to the public-house for that purpose. His mind can find employment where his body is at rest. There is in the mind of such a man an intellectual spring, urging him to the pursuit of mental good; and if the minds of his family are also a little cultivated, conversation becomes the more interesting, and the sphere of domestic enjoyment enlarged. The calm satisfaction which books afford puts him into a disposition to relish more exquisitely the tranquil delight of conjugal and parental affection; and as he will be more respectable in the eyes of his family than he who can teach them nothing, he will be naturally induced to cultivate whatever may preserve, and to shun whatever would impair that respect. * * * * * For producing steel pens the best Dennemora--Swedish iron--or hoop iron is selected. It is worked into sheets or slips about three feet long, and four or five inches broad, the thickness varying with the desired stiffness and flexibility of the pen for which it is intended. By a stamping press pieces of the required size are cut out. The point intended for the nib is introduced into a gauged hole, and by a machine pressed into a semi-cylindrical shape. In the same machine it is pierced with the required slit or slits. This being effected, the pens are cleaned by mutual attrition in tin cylinders, and tempered, as in the case of the steel plate, by being brought to the required color by heat. Some idea of the extent of this manufacture will be formed from the statement, that nearly 150 tons of steel are employed annually for this purpose, producing upward of 250,000,000 pens. * * * * * Philosophers abroad are working diligently at many interesting branches of physical science: magneto and muscular electricity, dia-magnetism, vegetable and animal physiology: Matteucci in Italy, Bois-Reymond, Weber, Reichenbach, and Dove in Germany. The two maps of isothermal lines for every month in the year, lately published by the last-mentioned _savant_, are remarkable and most valuable proofs of scientific insight and research. If they are to be depended on, there is but one pole of cold, situate in Northern America; that supposed to exist in the Asiatic continent disappears when the monthly means are taken. These maps will be highly useful to the meteorol
