"Delineations of the Ox Tribe: The Natural History of Bulls, Bisons, and Buffaloes" by George Vasey is a scientific publication written in the mid-19th century. This work aims to catalog and describe the various species and remarkable varieties of the genus Bos, which includes bulls, bisons, and buffaloes. It is illustrated by 72 engravings created by the author himself. The book is likely targeted towards naturalists and enthusiasts of zoology and animal biology. At the start of the book, Vasey sets forth his intentions and objectives for this comprehensive natural history. He discusses the distinct characteristics of the Ox Tribe while acknowledging the current gaps in knowledge surrounding this genus. The author articulates a desire for more precise classifications of species through comparison of essential anatomical features, which he hopes to encourage among travelers and naturalists. Key specifics, such as details about the digestive system and the rigors of rumination, are introduced as a foundation for understanding the complex physiology of these animals.
