Age Of Earth
Sir,—ln today’s report of my talk to the Canterbury branch of the Royal Forest and Bird Protection Society the age of the earth has been confused with the much briefer period of Canterbury’s history recorded in the rocks. 1 was dealing mainly with Canterbury during the last 250,000,000 years, but my analogy referred to the age of the earth which, based on measurements of the steady decay of radioactive minerals, is at least 4,500,000,000 years. To make this vast period of time more understandable I supposed that the earth had been formed in 1900, 66 years ago, and dated some of the major changes in life on this condensed time-scale.—Yours, etc.,
D. R. GREGG. Keeper of Geology, Canterbury Museum.
