In this handsome volume, Battezzati and Donini have contributed significantly to the complex matter of lymphocyte biology. The inclusion of this material illuminates the subject of immunological functions of the lymphocyte, and makes this more comprehensive than most books on the lymphatic system. The basic physiology of the lymphatics has been well delineated by Courtice and Yoffey in past years, but the present chapters give a good review of both the old and more recent literature on this subject. The pertinent references are numerous; unfortunately some significant writings, and some quoted authors, are omitted. Nevertheless, the material on lymphocyte physiology should have particular value to workers in this field. The anatomy and pathology of lymph nodes and lymphatics are covered in some detail. The sections on lymphangiography are extensive and well done, with interesting presentations of pathology demonstrated by supplemental techniques of simultaneous venography, tomography of visualized nodes, and scintillation
