This is a beautifully produced textual and pictorial presentation of scientific information pertaining to living things. It deals with five thousand separate subjects and twenty-eight regions of natural science, such as general biology, the biology of the human being and of plants and animals and so-called social biology, which has to do with the effects on living beings of their surroundings, ancestors, eugenics and evolution. The book is richly illustrated; there is scarcely a page without a line drawing, diagram or photograph. There are even touches of humor, such as the cartoon showing the tiger mother saying to her cub, "Eat the roughage too, dear," while in the picture are shown shoes and spectacles left over from the otherwise completely devoured victim.
There is nothing in the book to indicate for what age levels it is intended, but it should be a useful reference book at the high school level
