The "Field Trip Technique" emphasizes the importance of ensuring comfort and safety during field trips, with detailed instructions on planning and communication. It includes extensive descriptions of bus negotiations and a full letter to parents, suggesting a focus on procedural details over educational value. While the book supports conservation education, its high cost and emphasis on logistics may limit its appeal to teachers outside the U.S. In "The Foundations of Statistics," Leonard J. Savage's book is criticized for its title, which may mislead readers. The book discusses probability theories and defines statistics as dealing with vagueness and interpersonal differences in decision-making. Although Savage's approach to decision theory is welcomed, his reliance on minimax theory is questioned. The book is praised for its clear writing and stimulating content, despite criticisms of its focus on decision theory over statistical inference. "The Preservation of Natural History Specimens" is a handbook for museum curators, detailing techniques for preserving invertebrates. It includes systematic surveys of invertebrate groups, methods of killing, fixing, and preserving, along with appendices on apparatus, reagents, labels, storage, and microscopy. The book is well-organized, with clear illustrations and practical advice. While some methods are overlooked, the appendices provide a useful collection of formulas and techniques. The book is praised for its excellent format, clear type, and helpful illustrations, with anticipation of a second volume.The "Field Trip Technique" emphasizes the importance of ensuring comfort and safety during field trips, with detailed instructions on planning and communication.
