ARABIAN 'MEDICINE AND ITS INFLUENCE ON THE MIDDLE AGES. _
By Dr. Donald Campbell. (Kegan Paul. vols. 21s.)Students. of mediaeval thought and literature will welcome these two volumes. Vast in extent and but little explored, the Arabian literature is an essential part of any com- plete account of the development Of medical science from the Greek Era to the present day. As a iource from which future students may draw, Dr. Campbell's work is invaluable. If there are parts—the third chapter in particular—which are elementary, the broad sweep of tha survey, an outline and not an intensive study, renders that almost unavoidable. But the reconstruction of the Calcine Library is admirable and should do much to attract more students into this field of study.
