AGE OF THE EARTH.
According ,to Professor Allen, of Manitoba University, the discovery of radium has upset all Lord Kelvin's theories as to the ago of the earth. Lord Kelvin, who computed that the earth was 20 million years old, declared .that unless some new way. of . producing heat in the earth's surface could be found, his calculations were correct. .\ - 1 v. ■
, ; Such a new way has actually been discovered in radium, . which has the power of giving Out heat, without diminishing in weight. ' ■ - One -pound of radium would keep a house warm for ; 2000 years. - Radium is scattered throughout the earth's surface, and therefore radiuin give.s off helium, and helium is scattered throughout the earth's cru*t. By comparing the amount of radium arid of helium in a piece" of rock it would .be possible to form an estimate of t)ie earth's age, which he" asserted was over 1500 millions years.
