Pathological Histology

I HE apearance of a fourth edition of this boolk is evidence of its usefulness to students and practitioners interested in pathology. Its Xvalue lies in the unique collection of coloured plates. These are not intended as a substitute forthe stuLdy of nmicroscopic sections, but should serve only as a guide to them. Ihere is perhaps a tendency to illustrate conditions under too high a imiagnification, and some mray not accept somie of the illustrations, such as figures 76, 89, 90, 157 and 194 as entirely satisfactory. Despite these trivial criticisms the wvork is most valuable and the reproductions compare vary favourably with such coloured photo-micrographs as are available anywhere to-day. Wlhen the book is used beside the microscope-and it should only be used there-the accompanying text with its frequent discussion of incidence and aetiology is perhaps too detailed. The student might profit more by briefer notes which would guide him in the study of his histological sections anid wvhich would serve as models of how his own observations should be recorded.
