You Are Not to Suppose

That a shoe-black would make a firstrate teacher of etiquette, because he adds a certain polish to all who patronize him. Or that, when Vou receive a postal order, it is absolutely necessary to obey it. - Or that it is quite right of a fledgelifig artilleryman to boast that he has been “accepted by the E. A.” Or that you could blow a powerful and effective blast on an ink-horn or a shoe-horn. Or that a man whose stature is 5 feet 9 inches can possibly reach a height of 6 feet by becoming long headed in business. — 1 Renewed attention has been directed to some curious experiments made twenty-five years ago by M. Nicholas Wagner. It was then demonstrated that fixed electric currents exist in the wings of butterflies, and that the color of the wings is determined by these currents. Artificial currents changed the reds into orange, and blacks into red, and a constant battery produced spots varyingin shape with the strength of the current. By means of eleotricity, it was also possible to produce a kind of atrophy, and to change the shape of the wings. Electrical mining apparatus and the magnetio treatment of iron ores are exciting no small degree of interest among mining engineers.
