Platinum And Silver On The Sun

Up to 1888 platixmm had not as yet exhibited its presence in the sun's atmosphere. In that year some slight traces of it were found. Recent investigation establishes beyond a doubt the faot that it exists in the "great orb of day," as well as upon the earth. Th same investigations, which, of course, were made with the solar spectrum, oonfirm the belief in the prescnco of silver and bismuth in the suiaiso.
