...Animals and fish periodically thrive and decline. Many, notably lynx and salmon in Canada, have a cycle that averages nine and two-thirds years. A peak in elephants comes about every 62 years. Mice in the U.S. fluctuate in a four-year cycle; a plague sets them back every presidential-election year...
...processing it, is mild, spectacled Dr. Boris Berkman, onetime director of the Pasteur Institute in Moscow, for 20 years a surgeon on the staff of Chicago's Grant Hospital.

His hunch was right, and his discovery may well lead to development of a second group of bacteria-hoaxing chemicals comparable to the sulfa-group...
