A therapeutic manual, to serve any useful purpose, should either present new material or present well-established facts better than they can be presented elsewhere. To cover the management of disorders of the autonomic nervous system in 186 pages is beyond the scope of most experts who devote their lives to the subject. It has not been accomplished here. The chapters on anatomy, physiology, and pharmacology are routine, and there is not enough space available for including important details. To some extent, therapy is evaluated in terms of future hopes rather than observed and critically analyzed experience. It is unfortunate but true that books as short as this make almost impossible demands on the author to achieve needed compression without loss of essential detail or to present new experiences without restriction merely to one view of a problem.
