This Festchrift issue by a number of internationally recognized authorities in the field of orthodontic and craniofacial research is a testimony to the outstanding contributions of Dr. Koski on his sixtieth birthday. The names of the contributors alone should attract readers-among others, Cohen, Duterloo, Garn, Moyers, Graber , Herren, Horowitz, Isotupa, Kirviskari, Koskinen, Moffett, Kuroda, Miura, Leighton, Lundstrom, Moorrees, Moss, Moss-Salentijn, Petrovic, Stutzmann, Riinning, Enlow, Thesleff, Viljamaa. The articles are in English and cover a broad range of subjects, largely associated with craniofacial growth and development, with most of it at the cellular level. There are clinical articles, too, on rheumatoid arthritis, dysmorphic syndromes, macroglossia, mandibular third molar, space loss, anterior tooth guidance, profile radiographic and photographic orientation, etc. Issues should be available from the libraries of the American Association of Orthodontists and the American Dental Association, or one may write to the office of the journal, Rautatiellisenkatu 6, SF-00520, Helsinki, 52, Finland.

The groundswell of functional appliance courses, with strong emphasis on form and function and the responsiveness of bone to muscle forces, makes this fine book a “must” for all who would desire to understand the variable reactions of different types of bone to pressures. Because the mandibular condyle is an “in between” as far as membranous and endochondral bone are concerned, with some unique characteristics, the author felt impelled to write this book. There is neither a book nor a review article on chondroid bone (any tissue intermediate in nature between bone and cartilage). Secondary cartilages have received little attention in the literature. Metaplasia and modulation, which involve transformation of differentiated skeletal and nonskeletal cells to other cell kinds, is one step in condylar growth and, as yet, incompletely understood. The book attacks the issues head-on. A superb review of the literature and prior research efforts (and a fantastically complete bibliography) brings the reader through developmental and comparative anatomy to present concepts. The author uses the device of extensive quotations, allowing the reader to judge for himself what some of the authors had in mind. Each of the three subjects in the title is discussed in order and then elaborated with discussions of the undifferentiated mesenchymal cell, modulation, long-bone periosteal and insertion-structure chondrification, the mammalian skull, avian skull, antlers and horns, phallic bones, transplantations of skeletal tissues, bone and cartilagi-
