A POWERFUL MICROSCOPE. A German named Hasert, residing in Cincinnati, has manu- factured a microscope, which has a magnifying power of 600 The Cincinnati Times, speaking of its extraordinary powers, says the dust which, in contact with the wing of the butterfly, adheres to the finger, was shown to be a number of feathers on these little feathers are observed longitudinal and transverse lines, but this has been, so far, the utmost that has been seen. This new microscope, however, shows that between each pair of longitudinal lines there are five or six rows of scsles, like those of a fish, and appear to have the same form in all the feathers, differing only in size. A dust particle, taken from the back of the body of a sphinx, which is the largest of these feathers shown, measuring one-fifteenth of an inch in length, and one two-hundredth of an inch iu breadth, had 104 longitu- dinal lines. Between each pair of lines six rows of scales were visible, making the number of these little scales, laterally. 624 the number of scales, longitudinally, downwards, would be 2,228 therefore, tha entire number of these on this little fea- ther amount to one million four hundred thousand, which gives the number of fourteen thousand millions to one square inch. Oa a very minute particle of dust from the wing of a jimes, meaiuring only one fiye-hundredth of an inch in length, and one-thousandth of an inch in width, the number of scales is found to be 84,000, which gives the enormous sum of 42,000,000,000 to one square inch.
