Prof. John H. Skinkle's book on textile testing is welcomed by industry professionals and educators. It covers physical, chemical, and microscopical aspects of textile testing. The microscopical section on fibre identification could benefit from illustrations. The physical section includes various tests, while the chemical section discusses fibre relationships to carbohydrates and proteins, along with standard American methods. The book serves as a student manual and outlines current knowledge of fibre structures. It references the Journal of the Textile Institute and is a valuable addition to British textile libraries. However, diagrams are poorly reproduced and should be improved in future editions. Donald Alexander Johansen's book on plant microtechnique discusses advancements in microscopic techniques and life history knowledge. It provides detailed procedures from Stanford laboratories, emphasizing whole-mount preparations and thicker sections. The book includes stain preparation details and practical hints for laboratory work. It covers fixation, staining, microtoming, and specialized techniques, with a focus on adapting methods for various phyla. The book is particularly useful for Algae, Fungi, and lower types, offering life-cycle details, collection methods, preservation, and staining techniques. It applies to both elementary and less-studied groups, including Pyrrophyta and Lichens. Ibert Mellan's book on industrial solvents is a comprehensive resource on solvent properties, including fungicidal actions, solubility, and toxicity. It covers 180 solvents by chemical composition, with detailed information on important substances. The book includes a chapter on plasticizers and a section on graphical expression, though the structure could be improved with better organization and indexing. Despite some disorganization, the book is indispensable for solvent users.Prof. John H. Skinkle's book on textile testing is welcomed by industry professionals and educators.
