If Professor Howorth's argnnient is to be given a);y weight, tiio Kiberian ! platean is one of the most recent fea! tures in tbe known pliysical geography of tbe world. He fignrea that the pla tean was suddenly raised to its present j heigbt, and tbat, prior to its sudden ele! vatiou, it was a warm stretch of low land furnishing pastnrage to thousauds af mammoth brutos. Tbe rapid elevation, aceórding to bis deductions, suddenly oongealed tbe waters and froze tbe gigantic animal bodies throngh and through, tbus preserving them intact nutil tbe present day. He says that unless these animáis had been frozen imraediately alter death they would certainly have de.cayed and disappeared. In some places, far to the east iu Siberia, as well as in the mountninous regions of Alaska on our continent, tbe remains of tbe mammoth and other great sxtiuot animáis havo been found at a heigiitof K.000 feot above sea level. Howorth and Palcony both declare this to be incompatible with their mode of life.
