The text is the culmination of Dr. Friedman's interest in labor, and it brings together in an orderly manner the results of his graphic and statistical analytic methods of study. The monograph has five parts. The first deals with normal labor, the development of the methods of study and demonstration of their value and limitations, and review of known physiologic material. The second part analyzes the varieties of abnormal labor with particular regard to definition, etiology, therapy, and prognosis. The effects of endogenous and exogenous factors on the course of labor are covered in the third and fourth sections, respectively. The concluding portion presents programs of management of labor aberrations based on material presented earlier.
