The Cambridge natural history, Vol. 10 (of 10)

"The Cambridge Natural History, Vol. 10 (of 10)" by Frank E. Beddard is a scientific book from the early 1900s that explores the fascinating world of mammals, from those roaming the earth today to those that have disappeared over time, intending to be a helpful guide for students and experts alike. The book is part of a series aiming to describe various aspects of the natural world, and it explores many things, aiming to be a resource for anyone keen on biology. The opening section is an author's note in which Beddard acknowledges the difficulty of fitting so much information into a limited amount of space, and gives insight into how mammals are organized and grouped, highlighting their unique features like mammary glands, their development over millions of years, and the story of how they were first studied. This sets the scene for a detailed examination of the different kinds of mammals and how they have changed and evolved in the chapters that follow.
