Excerpt from British MammalsGreat Britain has some forty species of land mammals as against Germany's ninety and Scandinavia's sixty, while Ireland has only twenty-two. In Reptiles and Amphibians a small country like Belgium has about twenty-two species, while Great Britain has thirteen, and Ireland only four, of which none are Snakes. This extreme poverty has been accounted for by the destruction caused by the glacial epoch during Pleistocene times, and to some extent by the subsidence and ¿ooding of the country which occurred during this epoch.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
