Animal Locomotion; or, walking, swimming, and flying
 With a dissertation on aëronautics

by James Bell Pettigrew

"Animal Locomotion; or, Walking, Swimming, and Flying" by James Bell Pettigrew is a scientific publication written in the late 19th century. This work explores the mechanics of movement in various animals, focusing specifically on their modes of locomotion across different environments—on land, in water, and through the air. The book aims to elucidate the principles underlying the physical forces and structures that enable animals to move effectively and elegantly. The opening of the book introduces the topic of animal locomotion as a fundamental aspect of life that is inherently intertwined with the survival and well-being of creatures. Pettigrew emphasizes that motion is not isolated to the animal kingdom but is a characteristic of all matter, drawing connections between natural phenomena and the potential for artificial movement. Through engaging descriptions, he illustrates the beauty and complexity of animal movement, setting the stage for a detailed examination of walking, swimming, and flying as interconnected themes of progression within the natural world.
