 The hearing organ of animals is gen. orally double, but not always located in the head. In the clam it exists at the base of the loot Tn some grasshoppers it is in the fore legs, and it appears on the wings of ID any ir sects. The auditory sacs of Holsters ana crabs are at the base of the antenne.
 A vegetable leather, said to be fully equal to the animal product, is made in Paris IT om gutta percha, sulphur, raw cotton, zinc white, kolkothar, and oxide of antimony.

 By means of that remarkable instru- ment of modern research, the spectroscope. the otherwise absolutely imperceptible mo- tion oi so-called fixed stars is not only de- tected but measured. Sirius is found 10 be now approaching the earth at the rate of twenty miles a second, while few years ago this notable star was receding from us twenty-five miles each second.
 Bees in unaccustomed localities. ac- cording to H. Muller, are timid, and find honey with difficulty, but rapidly become ac- custemed to their surroundings. Flowers of subdued colors are selected by bees instead of the more brilliantly colored ones. Blue or violet appears to be most attractive, and bright yellow the least so. Fabre has found that many bees are able to return to their nests when carried to distance.
 Natures Transformation tadpole. the larva of frog, has a tail and no legs. gills instead of lungs, heart precisely like that ot a fish, horny beak for eating vegeta- ble food, and spiral intestine to digest it. With the approach of maturity the hind legs appear, then the front pair; the beak falls of the tail and gills waste away; the lungs are created; the digestive apparatus is changed to suit the animal diet the heart becomes reptilian in type by the addition of another auricle; in fact, skin, muscles. nerves and blood-vessels vanish. being absorb.d atom by atom, and a new set is substituted.
 Life in Other Worlds.-"ln In the pres ence of time intervals, ," says one of the abIest of modern astronomers, "seen to be at once 1T finitely great and infinitely li,tle-infnitelv great compared with the duration of our earth, infinitely little by comparison with the eternities amidst which they are lost-what reason can we have when viewing any orb in space from our little earth, for saying now is he time when that orb is, like our earth, the abode of lifel Why should life on that earth 'ynchronise with life on this earthi Are not. 'n the contrary, the chances infinitely great against such a coiHcidencel If, as Helm noltz has well said, the duration of life on 'ur earth is but the minutest ripple in the infinite ocean of time,' and the duration of lte on any other planet of like minuteness. what reason can we have for supposing that hose remote, minute, and no way associated waves of life must needs be abreast of each other on the infinite ocean whose surface hey scarcely ripplea Whether we urn our thoughts to planet, sun, or galaxy. he law of nature Recognized as universal within the domain as yet examined), that the luration of life in the individual is indefi- litely short compared with the duration of he type to which the individual belongs, as- ures us, or at least renders it highly proba- lie, that in any member of any of these or ers taken at random, it is more probable hat life is wanting than that life exists at this resent time.
