The review discusses several books, each with its unique focus and contributions: 1. **A Book on Chemistry**: The book is primarily about inorganic chemistry, with some chapters on physical chemistry. The first ten chapters are well-written and useful for medical and hygiene applications, but the treatment of metals is limited. The organic and biochemistry sections are less comprehensive, though the chapter on vitamins is interesting. The laboratory experiments section is praised for its practical value. 2. **The Elements of General Zoology**: This book differs from others by focusing on the functions of structures, such as nutrition, respiration, and excretion in single-celled organisms like amebae and paramecia. It also covers the evolution and organs of multicellular organisms. The book includes laboratory work instructions and is valuable for medical students. 3. **The Indian Materia Medica**: This compilation covers drugs used in Ayurvedic and Unani systems of medicine, including home remedies. It provides detailed descriptions of plant habitats, active principles, and uses, but lacks recent scientific research. It is useful for students and researchers of indigenous medicine. 4. **A Textbook of Exodontia**: The book covers general anesthesia, with a preference for a specific sequence of gases. It highly recommends novocaine for dental operations and provides detailed instructions on extra-oral injections and blood control in oral surgery. The chapters on extraction are comprehensive, making it a valuable resource for dental surgeons. 5. **Tiger Trails in Southern Asia**: This book, written by a dermatologist and tiger shooter, offers a fascinating account of tiger-shooting in Indo-China and Assam, with detailed descriptions of tribal customs and original photographs. It appeals to naturalists, anthropologists, and enthusiasts of "shikar." 6. **Surplus Fat and How to Reduce It**: This book, aimed at laymen, provides a common-sense approach to obesity, emphasizing the importance of lifestyle changes over quick fixes. It is well-illustrated and offers practical advice for managing obesity. Overall, the reviews highlight the strengths and unique contributions of each book, emphasizing their value for specific audiences.The review discusses several books, each with its unique focus and contributions: 1. **A Book on Chemistry**: The book is primarily about inorganic chemistry, with some chapters on physical chemistry.
