The review of "Electron Microscopy of Cells and Tissues" by Fritiof S. Sjöstrand highlights the book's strengths and weaknesses. While the author praises the book for its fast, scholarly, and significant content, particularly in developing techniques and judgment, he notes that the book lacks depth in its treatment of chemistry and physics, which are crucial for understanding high-resolution electron microscopy. The review also criticizes the inadequate coverage of staining reactions and the overemphasis on autoradiography. Despite these shortcomings, the book remains valuable for its general overview and practical insights. The review of "Methods in Enzymology: Volume XI, Enzyme Structure" by C. H. W. Hirs is positive, praising the volume for its comprehensive and detailed coverage of various techniques in enzyme structure. The book covers a wide range of topics, including amino acid analysis, end-group analysis, subunit separation, cleavage of disulfide and peptide bonds, peptide separation, sequence determination, and modification of enzyme structure. The review highlights the broad applicability of the techniques presented, making the volume useful for a wide range of researchers. The review of "Neuropsychiatry in World War II" by Col. Robert S. Anderson and others focuses on the mobilization, manpower, selection, training, and utilization of military personnel in terms of neuropsychiatric issues. The review suggests that the title "To Conserve the Fighting Strength" more accurately reflects the book's content, given the significant number of military personnel classified as neuropsychiatrically impaired during World War II.The review of "Electron Microscopy of Cells and Tissues" by Fritiof S.
