Abstract

IN my letter in NATURE of Feb. 7, p. 200, entitled “Embryology and Evolution”, I referred to a correlation between magnetic solar radiation and the reproduction of fur-bearing animals. Statements to the effect that such a correlation has been proved to exist are frequent, and are also found in certain text-books, but there seems to be considerable doubt as to their validity.
