who has already written a well-known work dealing with the affections of the vertebral column, now presents in this small volume a collection of essays on certain aspects of general bone and joint diseases. It is in no sense a formal description of the common diseases, but rather a special presentation of rare conditions or of special aspects of common diseases. Among the diseases of dcveloprnental or congenital origin the author describes generalized osseous dystrophy under the term 'familial pleonosteosis'. He also has sections dealing with hypochrondroplasia, cleidocranial dysostosis, facial hemiatrophy, oxycephaly, multiple esootoses, and anencephaly. Among the acquired diseases of bone he discusses rickets, osteornalacia, Paget's discase, von Recklinghausen's disease, and the syphilitic affections of bone. The section on articular diseases is confined almost entirely to rheumatoid arthritis, with special refcrcnce to the nodosities forming in the periarticular structures. Thc most valuable part of the work is the carefully written histories of individual cases illustrating the rarer conditions. The figures in the book do not do justice to the subject matter as they are very poorly reproduced. agrkg6 B la Facult6 de MIedecine de Paris. 1927. Paris: bfasson et Cic. Fr. 58.
