A book for the rapid reviewing of facts in a science is occasionally an aid to a candidate for an examination but is ordinarily useless for study. This book is reasonably accurate and is well composed. It is essentially a dictionary arranged under the conventional headings of the physiologic and anatomic subdivisions of the body. All aspects of the subject are covered, but in brief and dogmatic form. One defect in such a work is that the reader has no way of knowing which of the statements are well substantiated and which are not. In physiology today many qualifications must be made and questions left unanswered because of inadequate knowledge. It would be highly undesirable to recommend this work as a student's textbook.
