sence ofzinc and aluminum in the sun had hitherto been extremelydoubtful, as only very few lines of their spectra had beenfound inverted in the solar spectrum ; this doubt we maynow consider as removed, since the author has found thatthe lines corresponding to these elements in the solarspectrum are the longest lines of the spectra of their va-pors. KONGSBERGITE-A NEW SILVER-AMALGAM. By F. Pisani.—A sample of native silver of a dead-whitecolor, from the Konsberg mine in Norway, occurring inlarge cubes, the angles of which were often deeply trun-cated, gave on analysis, silver = 95.26, mercury = 4.74.Another sample from the same place, the crystals of whichwere smaller and not so well defined, of a brass-yellowcolor from iridescence, gave silver = 94.94, mercury =5.06. The mean of these two results corresponds withthe formula, Ag36Hg. If the above composition be notaccidental, but be confirmed by the discovery of otherspecimens, it is proposed to call the mineral Kongsbergite. (4-32)

Does Science teach that other worlds areunpeopled deserts, serving no other purpose than to tra-verse their orbits obedient to the divine will ? Such arethe questions which astronomers have been forced tomeet and answer, unaided except by the testimony afford-ed by analogy and by deductions from theory, based per-haps on evidence mainly presumptive. Mars is frequently visible in the evening heavens, aruddy star in or near the constellation Virgo. Forty mil-lions of miles, at least, divide us from the bright globe oflight which modern revelation tells us is the miniature ofour own earth ; 5000 miles is its diameter. Comparing therelative densities, Mars
