ABSTRACT

THE Growth of the Brain. It is not so logical as it seems to give an account of the growth of intelligence and of the brain together; for the size of the latter and the number of its nerve cells are not inevitably closely related to the amount of intelligence. Quality, not yet definable in physiological or anatomical terms, is as important as quantity. The brain of some idiots is as large and contains as many nerve-cells apparently as the brain of a normal man. Anatole France’s brain was smaller than the brain of the average farm-labourer.
