Sách nói: Elements of Mammalogy

The Elements of Mammalogy is one of seven in a Series of First Books of Natural History Prepared for the Use of Schools and Colleges. This succinct little textbook from 1845 presents an introduction to mammalogy. The information, albeit not current, is still interesting and of use as a general overview of mammal biology. The classification of mammals has changed considerably since this time. The author was a surgeon in the U.S. Navy and president of the Academy of Natural Sciences.
