A small popular-science book that walks the reader through the animal kingdom: how animals adapt to their surroundings, how zoologists classify them, and then group by group from one-celled protozoa, polyps and sponges to worms, molluscs, insects and the backboned animals, with diagrams drawn from specimens at the Natural History Museum in South Kensington.
A clear, friendly introduction to zoology as it was understood at the turn of the century. Download the free EPUB.
