Detectives of Time
Time detectives using atomic tools are piecing together a new and dramatic picture of the past, reaching back as far as 25,000 years. N. J. BERRILL, who gives us the clues to this fascinating discovery, is a lifelong student of the sea, a marine biologist now serving as Professor of Zoology at McGill diversity. Atlantic readers will remember his book Journey into Wonder, an account of the voyages and explorations of the great naturalists, from which we published three chapters last year.
