Beginselen der dierkunde
"Beginselen der Dierkunde" by J. Ritzema Bos is a scientific publication written in the late 19th century. The work serves as an introductory overview of the animal kingdom, particularly focusing on classes relevant to agriculture, such as mammals, birds, and insects, aiming to inform both agricultural education and secondary school curricula. It presents essential concepts in animal biology and anatomy, aligning content with practical applications for farmers and educators. The opening of the book begins with a preface outlining its purpose and structure. It emphasizes that the text is designed to provide an accessible overview of the entire animal kingdom while delving deeper into specific classes of interest, particularly for those involved in agriculture. The author mentions the need for selective teaching methods, indicating that while the text offers a thorough framework on various animal types and their functions, it allows for flexibility in lesson delivery. The subsequent chapters provide detailed discussions on the anatomy and life processes of animals, establishing the groundwork for a more extensive examination of animal biology.
Agricultural zoology
"Agricultural zoology" by J. Ritzema Bos is a scientific handbook written in the late 19th century. It surveys the animal kingdom with an emphasis on species that harm or help farming, offering clear identification, biology, and practical notes for students and working farmers. The opening of the book sets its purpose and audience in the author’s and translator’s prefaces, with Eleanor A. Ormerod’s introduction underscoring its practical value; a detailed contents list signals broad coverage from vertebrates to protozoa. It then explains zoological classification and binomial naming, followed by a concise primer on vertebrate anatomy and physiology (skeleton, muscles, nerves, digestion, circulation and respiration, reproduction including alternation of generations), and how heart structure differs across vertebrate classes. The text proceeds into applied accounts of mammals relevant to agriculture: cats, dogs, foxes, and mustelids (marten, polecat/ferret, stoat, weasel, mink, otter, badger) with balanced notes on damage versus benefits; insect-eaters (shrews, the mole, hedgehog) largely presented as allies; bats as valuable nocturnal insect hunters; and rodents (hares and rabbits, then mice and rats) with concise identification and their typical harms. This opening portion concludes mid-discussion of mouse and rat species and their agricultural impact.
