The Mining and Scientific Press. 9 foal 7 Meteors axp Cosers,—Professor Pep. per, in his Lenten Lectures on * physical astronomy,” at the London Royal Polytechnic, stated that fourteen years aga Dr. Bedford discovered the relution between meteor and comet, and announced their netual identity ; that at the time, and long since, it was regarded as mere theory ; but within the last two yenrs astronomers have proved the truth of Dr. Bedford's discovery, which was made by a careful comparison’of recorded plenomenn from the earliest times. The VDrofessor suid thnt it had been proved by fivo mathematical elements of the orbits of five several comets nud meteors, and that tho discovery is regarded as one of the grandest additions ta ustronomicul seience; and stated that Dr. Bedford lias propounded entirely new theories of astrononiy, whielt are most profound and very interesting, and we!l worthy ef heing studied. Minerats ix Missount.—Lead is found in more than 500 localities in Missoni. The yeius run through twenty ceunties, aud nre sprend over an area of about 6,000 square miles. The ore averages seventyfive per cent. ef pure lead. Copper has heen found in fifteen counties. Ziue is also very abuudant. Little attention is, how over, paid to either lead or zine. Wo hear nothiag of late of the tin miues. Iron, mostly speculur, ahounds in inexhanstihle quuutities, averaging about fifty per cent. pure iron, of n very superior quality. Coal hus been found nnderlyiug thirty counties, reaching au aggregate area of about 27,060 acres, with © mean thickness of eight feet. Tue retail sales of iutoxicating drinks in the United States, it is estimated, anionut every year to the tetal value of all the railroxds in tho Uniou—about $1,500,000, 000! GEO. EH.
