This monograph by Dr. A. R. Miller explores the thermodynamic behavior of high-polymer solutions, a topic of significant current interest. The book highlights the importance of understanding the physical properties of these solutions to determine molecular size and shape. It discusses the challenges in modeling high-polymer solutions due to their deviation from ideal behavior at all concentrations. Dr. Miller presents a statistical thermodynamic approach, calculating the free energy of mixing under the assumption that the solution is athermal. Despite limited experimental data, the theory shows surprisingly good agreement with experiments, indicating that the theoretical approach is on the right track. However, more experimental work is needed to refine models for statistical treatment. The second edition of J. M. Black's "Flora of South Australia" covers the families of Dicotyledons from Casuarinaceae to Euphorbiaceae. This practical flora includes keys, descriptions, and illustrations, making it a valuable resource for botanists and ecologists. The book discusses various families, such as Casuarinaceae, Proteaceae, Chenopodiaceae, and Leguminosae, highlighting their species diversity and distribution in South Australia. It also notes the presence of introduced species and endemic genera, providing a comprehensive overview of the region's flora. Prof. Ira D. Garard's "An Introduction to Organic Chemistry" is designed for students in agriculture, home economics, and medicine. The book covers the simpler aliphatic and aromatic compounds, along with practical work schemes. It emphasizes the economic uses of organic compounds and omits complex theories, making it accessible and engaging. The author includes detailed information on proteins, rubber, nylon, and dyes, and provides clear explanations of unusual terms and new materials. The book is praised for its readability and relevance to students in these fields. The "Pharmaceutical Pocket-Book" is a comprehensive reference for both pharmacy students and practicing pharmacists. The 15th edition includes updates from the 1948 British Pharmacopoeia and summaries of relevant provisions from the National Health Service Act. It covers biochemical analysis, bacteriology, and a dictionary of synonyms and trade names. While the dictionary is outdated and lacks modern synthetic drugs, the book remains a valuable resource for pharmacists, offering a wealth of information.This monograph by Dr. A. R.
