To use the authors' own statement, this book is a “readily available compendious and expository source” of information relative to transfusions. If individuals having no knowledge of the various methods of administering whole blood or plasma and storing whole blood or plasma had access to only one book, this compilation most nearly would fill all requirements. The book is based on the experience derived from some 7,000 transfusions and almost half that many references to the literature. For example, one chapter contains 913 references in its bibliography. There is an apparently unavoidable amount of repetition in certain chapters, particularly as regards the military use of blood or plasma and various statements made will sometimes seem contradictory. This perhaps may be related to the dual authorship. Scattered typographical errors are noted, as for example, the statement is made that “Aletrin in a dosage of 0.3 grams” should be used in the treatment of malignant tertian malaria.
