Dr. Van Dongen’s thesis is of particular interclst to the embryologist. While thtk devf~lopment of the articulnr disc has been assumed t,o hc closely related to the lateral ptrrygoitl Dr. Van T)ongen found that in embryos of 50 to 80 mm. a musrle l,y most invrstigntors, change of position is effrctc,d in the tc~Inporor~~andil~ular area tjctwcen the mandibular c~ondyle and the temporal squama, ljoth structures undergoing a marked change. The movement of thcl condylc laterally, lrc states, is due to secondary cartilage of the manditmlar condylr growing not only in an occipitocranial t)ut, also in a lateral direction. The growth is closely relatcad to a mesc~nehymal condensation locatrd between this area, thr temporal squama, and the occipital part of Meckel’s cartilage. Thcl temporal squama undrrgo(,s a considernhlc change, and ther+~ are indications that the mesrnc~hpmal ared l)rtwren the condplar area, temporal squama, Mrckel’s cartilage, and partic’ularly a. very dc>nse strip in it, which the author assuniPs t,o 11c tho potential articaular disc, plays a role in thr al,ovc,-Inentionetl changes.

This monograph deals with the postnatal growth and development of hone. It tlrscril)es primarily the complex behavior of hone tissue during the growth of the skull. The introductory chapters serve to expand the scope of understanding of the basic principles. These are important for the reader to review, since in the current medical and dental curricula the time given to them is continually being reduced. Part II deals with an analysis of growth in the human rraniofacial skeleton. It gives a detailed account of events involved in the maturation of each individual bone of the skull, correcting the misconceptions which exist, regarding skelrtal growth. This especially refers to the assumption that growth of hone is an interstitial process similar to that of soft tissur. Bone, the author stat@ cannot develop 1)~ internal expansion because its matrix is calcified. A stries of much more complcs events is involvrd, a description of which comprises the main part of the book. This is a fascinating book, c%pecially for thr scientifically inclined reader, he he an orthodontist, a periodont,ist, or a research-mindrd individual of our profession. It is well illustrated 1)~ Mr. William Brudon, who has worked closely with the author in translating the difficult concepts involved into meaningful intcrpret,ive diagrams a.nd photographs. K. H. 7’.

This is the sc,cond edition of a great book. Several new chapters have l)t~c~n addeti--RI) rntirely new cahapter on head injuries t)y Mr. J. E. A. O’Connel, and one on the care of the unconscious patient 1)~ Dr. C. Cr. Surer. Among the othclr distinguishrd contributors should he mentioned Messrs. Patrick Clarkson, Conroy, Ennis, Gilchrist,, the late Sir Harrold Gill& Holdsworth, Kay, Kramer, MeCash, Romanes, and Walker. Outstanding features of the second edition are a chapter on the healing of fracturc>s, prosthetic replacements, and injuries of the zygomaticomaxillary process. The interesting contribution on medicolegal aspects of injuries of the face by Brigadier D. V. Taylor of thr Royal Army Dental Corps, who is also a barrister-ablaw, should be especially mentioned, because many such injuries frequently leave permanent defects and end in litigation. This book is encyclopedic in nature and describes practically all methods of treatment of facial injuries, with sp(xcial attention given to those that are favored today. It is a comprehensive text of interest to oral surgeons, plastic surgeons, dental surgeons, orthopedic surgeons, aud ophthalmic surgeons. The book is profusely and well illustrated, and the publishers have produced an outstanding addition to our literature. K. H. T.
