The reviewer William L. Kissick provides a brief overview of the book "Preventive Medicine for Medical Students, General Practitioners, Specialists, and Professional Workers in Official and Voluntary Health Agencies." The book covers a range of topics from communicable disease control to the newer responsibilities of hazards of ionizing radiation and medical defense against atomic attack. The content is well-organized and concise, with references listed after each chapter for further reading. Two chapters, "Epidemiologic Methods and Inferences" by Dr. Dienfeld and "Official and Voluntary Health Agencies" by Dr. Hilleboe, are particularly well-discussed. The reviewer concludes that the book serves its purpose as an introductory text rather than a comprehensive reference. Joseph Thomas Velardo reviews "Histochemistry, Theoretical and Applied" by A. G. Everson Pearse. The book reflects the rapid and clear development of histochemistry, with significant expansions in content and illustrations compared to the first edition. The author's clear expression and simplifications of methods make the subject accessible. The book covers historical background, practical techniques, and detailed appendices on tissue preparation, along with extensive bibliographies. The reviewer praises the book's quality and clarity. Donald J. Hanahan's "Lipide Chemistry" is reviewed by another author. The book provides a comprehensive survey of recent work on lipid chemistry, emphasizing the importance of understanding lipid structures for biochemists, physiologists, and clinicians. It covers simple lipides, phospholipids, and lipoproteins, with a focus on mammalian origins. Each class of lipids is discussed critically, and the book includes up-to-date references. However, the reviewer notes the lack of a complete index, which could be beneficial for students and advanced investigators.The reviewer William L.
