Perhaps the most popular science of the day is biology.

It asks that concentration on exact observation and that distrust of intagination which seem so congenial to the modern mood. It is fairly certain, therefore, that Dr. John Baker, who is at present broadcasting a series called "Biology in Everyday Life," will have an extensive following among listeners. He is certainly a lively broadcaster : terse and vivid, he is quite capable of imparting an acid flavour to his words such as I feel sure adult study circles must approve. His talks will continue (on Tuesday evenings) until the end of the month ; and Professor J. B. S. Haldane will wind up the series on April 4th with a talk -on "Biology and States- manship."
