Abstract
THIS handy and very moderately priced laboratory guide will be useful in those courses of elementary instruction in zoology which aim at a fairly wide survey of the types of animal life without >going into great detail in regard to any. Thus there are instructions in regard to six Protozoa, two sponges, three Hydrozoa, a rotifer, three Echinoderms, the earthworm and Nereis, Cyclops, the wood-louse, the lobster, the crab, the centipede, three insects and a spider, three molluscs and three vertebrates, altogether thirty-two types. The directions for study are for the most part really directions, and not little paragraphs of condensed information; many of them take the form of questions. The student is not supplied with ready-made diagrams; he is asked precisely to draw certain things. There is a directness and business-like clearness about the whole book that we like, and its partiality is frankly admitted, supplementary text-books being indicated. It would have been well if the authors had always stated what particular species they had in view, e.g. what Tubularian and Campanularian hydroid or hydroids. In some cases the headings do not read very happily, if the book is to be used in Britain, e.g.“ The simple Marine Sponge (Grantia sp.). This sponge is a marine animal, found commonly along the Atlantic coast of the United States.” But we can recommend the little book as a terse, unpretentious, and clear guide to introductory studies of the structure of animals.
