Atlas of Human Anatomy

wall between the disciplines of structure and function. The obvious need for precise quantitative description of morphology of whole organs for correlation with functional data already available in abundance has too long been frustrated by the prohibitively time consuming and primitive techniques heretofore available. By the combination of a few new mathematical formulations with several expressions and methods previously used by others, especially in geology, Weibel has devised for the first time a practical technique for morphometry. This book combines a number of his preliminary communications with considerable additional detail and expansion. All of the theoretical aspects as well as the "cook book" rules for application are described. In addition, the results of Weibel's measurements of pulmonary anatomy are reported. The prospective reader should not be misled by the restrictive title, for the system is readily applicable to many structures besides the lung. Morphometry as here described is not yet so simple as to enable overnight results of routine application. Nonetheless, a system within the realm of possibility is now available, and reports of applications based on Weibel's earlier publications have already begun to appear. For those who need precise structural measurements, from gross to ultrastructural scale, this monograph will be not only useful but essential. c. B. CARRINGTON
