General Texts For the general medical public, there are three recent volumes for orientation in the field of neurosurgery. Somewhat forbidding because of the wealth of detail (which makes the book all the more useful as a source) is L. Davis and R. A. Davis'Principles of Neurological Surgery(Saunders, 1963, $15). Methods of examination, including illustrated techniques for muscle and nerve testing, are particularly well covered. Such minutiae are deliberately omitted from W. B. Jennett's AnIntroduction to Neurosurgery(Thomas, 1964, $9.50). This has excellent coverage of principles of operations rather than details. Spinal and peripheral nerve injuries are considered orthopedic problems and hence are omitted. A slightly older book by Sean Mullan,Essentials of Neurosurgery for Students and Practitioners(Springer, 1961, $6.75), uses penand-ink representations of the drawings which Mullan uses in his lectures, to clarify the points in the text.
