This comprehensive work surveys the anatomy, classification, natural history, and economic significance of mammals, both living and extinct. It is aimed chiefly at students of zoology and other readers interested in mammalian biology, providing a detailed but accessible overview rather than an exhaustive treatise. The opening of the book begins with a preface outlining the authors' intentions to balance detail with accessibility for general readers and students, explaining their reliance on and integration of previous scholarly works and illustrations. The first chapter introduces the concept of "Mammalia," tracing the term's origin and clarifying its boundaries with other vertebrate classes. It covers the evolutionary history, anatomical traits, reproductive strategies, ecological diversity, and the immense practical importance of mammals to humans—including their roles in labor, food, clothing, and other products. In the initial portion of the second chapter, the book delves into anatomical detail, describing structures such as hair, coloration, scales, nails, claws, hooves, and various scent glands, before launching into an extensive discussion of mammalian dentition, emphasizing its biological and taxonomic significance.
