Galilio, Isaac Newton, Pasteur and Faraday are the predecessors in this series, by varying authors. This is the first by Millicent Selsam, whose nature books are widely known. Probably the scope of Captain Cook's explorations and the botanical significance of much that he brought back captured her interest. In any case, she has done a first rate job in bringing the three voyagen into the space limitations imposed. She has told Cook's extraordinary story with vividness, pace and full appreciation of the immense achievement, and the richness of his findings for science and the world. The somewhat rigid illustrations by Lee J. Amos have more decorative quality than beauty; one could wish that the wooden human figures could have been omitted, and the lovely drawings of decorative maps and ships are more than enough.
