INTRODUCTION  In this paper we are concerned with the technical problems bearing on the measurement of the human cerebral cortical surface. This is an anatomic or morphologic method of measuring the capacity of that organ without which we are devoid of the possibility of being intelligent or indeed, of being at all. This method forms a contrast to those which seek to know the capacity of this structure by observing the results of its activity which constitute behavior.The various aspects of the problem as we now envisage it are as follows: (a) the evolution of the main organ of intelligence in various vertebrates from the lowest to man; (b) the growth of this organ, i.e., of the surface of the cortex
