Gr 4-6-These biographies examine the lives and achievements of two great scientists. In both books, Fullick tries to set the scene by describing the men's families and the times in which they were born. Much attention is given to Darwin's five-year voyage on the H.M.S Beagle, which formed the basis of the scientist's great work, The Origin of Species. Pasteur's French background, his research, and the impact of his discoveries on medicine and science in general are all related. Unfortunately, the books are written in a merely adequate style, rife with colloquialisms and an overabundance of exclamation points. The layout and quality of the full-color and black-and-white illustrations are fair. Steve Parker's Charles Darwin and Evolution and Louis Pasteur and Germs (both Chelsea, 1995) present much of the same material more attractively, if for a slightly younger audience. Fullick's titles are serviceable additions for those who need more material on these men.-Anne Parker, Milton Public Library, MA Copyright 2001 Cahners Business Information.
