This is a specialized monograph on the thermodynamic behavior of high-polymer solutions, which is of great current interest. The book discusses the importance of understanding the physical properties of high-polymer solutions to determine molecular size and shape, and to gain insight into the complex problem of their behavior. The author, Dr. A. R. Miller, presents a statistical thermodynamic approach to the problem, choosing an acceptable model and developing its consequences. Although there is not a wealth of experimental data, the agreement between theory and experiment is surprisingly good, indicating that the theoretical approach is correct. The book also addresses the complications that arise when the simplification does not hold, and emphasizes the need for more experimental work to develop more accurate models. The second edition of J. M. Black's "Flora of South Australia" is published, covering the families of Dicotyledons from Casuarinaceae to Euphorbiaceae. The book includes keys, descriptions, and illustrations, making it a practical flora. It is issued by the South Australian Branch of the British Science Guild, now incorporated with the British Association for the Advancement of Science. The book covers families of particular interest, including Casuarinaceae, Proteaceae, Chenopodiaceae, and others. The species of these families are described, with some being endemic to Australia. The book "An Introduction to Organic Chemistry" by Prof. Ira D. Garard is a concise course on organic chemistry for students in agriculture, home economics, and medicine. It covers the simpler aliphatic and aromatic compounds, along with a suitable scheme of practical work. The book is readable and includes discussions on the economic uses of organic compounds. The book is well-written and includes tables and explanations of unusual terms. The "Pharmaceutical Pocket-Book" is a reference book for pharmacists and students of pharmacy. It includes the latest changes from the British Pharmacopoeia and information on the National Health Service Act. It contains a dictionary of synonyms and trade names, though it is outdated and lacks modern synthetic drugs. Despite this, the book contains much useful information.This is a specialized monograph on the thermodynamic behavior of high-polymer solutions, which is of great current interest.
