The teeth carved natural size are then to be set in centric occlusion in a half jaw articulator. i\ccompanying the directions for setting up the teeth is a brief discussion of functional form of teeth, alignment, curvature of the dental arch, contact relations, occlusal contact, and intercusp relations. The fourteen maxillary
book is well illustrated. There are photographs of representative natural teeth (third molars omitted), and drawings of representative and mandibular incisors, canines, first premolars, and first molars.

understandable and nonrepetitious. The illustrations a quick and correct grasp of tooth anatomy.
Ambiguities and errors are few. From the point of view of smooth, easy reading, a revision of sentence structure in several places would be helpful. In some instances the substitution of the words cervical and occlusal (in&al) for above and heloze (or vice versa) would avoid confusion. Clarification of the crown length measurement on the graph-paper drawing of the maxillary first molar seems to be needed. It is unfortunate that there were not included more detailed descriptions of the occlusal surfaces of the molar teeth. Aside from a few such oversights, this manual looks like an excellent addition to the study aids in tooth anatomy, and it may be expected to be received enthusiastically by teachers and students alike in the fields of dentistry, dental hygiene and. dental laboratory technology.

This reviewer believes that in this sort of composition the author must too generally presuppose what questions will arise in the readers’ and students’ minds, that there is needless repetition in the answering of question< which are similar, and that it is much more difficult to locate the exact reference information being sought. The descriptive essay type of text would have lent itself better to classroom teaching. Also, the volume might have greater universal acceptance if the author had shown less prejudice in favor of one certain type of clasp and had given, instead, a broad illustrative coverage of all types oi clasps along with the pros and cons of the different metals used tcS provide clasping function. Further, since photographic cuts do not stand out as clearly and sharply defined as heroic, schematic line drawings, more use of the latter would have greatly clarified the various leverages which result in functioning partial dentures and would have added much toward a complete and more lucid coverage of removable partial denture designing. Perhaps it should be borne in mind that the omission of material which this reader considers so pertinent may be justified on the basis that one volume cannot be expected to cover everything on the subject. Since no other book even vaguely similar is available, it becomes a “must.” The treatise is by far the most comprehensive on removable partial denture prosthesis furnished the dental profession for many years, and the author is to be highly commended for making the great effort and sacrifices to bring about this vast contribution.
