Men of Science and their Discoveries and Pioneers of Invention

(Harrap's " Readers of To-day," ls. Od. each), by William and Stella Nida, are two excellent and very simply written volumes which every boy and girl should have. " The Friar of Oxford," " Galileo and the Telescope," Louis Pasteur Discovers Germs," Radium, the Magic Metal," " Plants and a Plant Wizard," are some of the chapter titles from Men of Science. It is curious that Sir Jagadis Bose is not mentioned in this last connexion, although, of course, the title does describe the late Luther Burbank.
