It was a saying of the late Dr Henry Maudsley: “Sex lies deeper than culture.” By this we may understand to be meant that sex differences are organic. All authorities on the physiological question are agreed that woman is less well-organised, less well-developed, than man. Dr de Varigny asserts that this fact is traceable throughout the whole female organism, throughout all its tissues, and all its functions. For instance, the stature of the human female is less than that of the man in all races. As regards weight there is a corresponding difference. The adult woman weighs, on the average, rather more than 11 lbs. less than the man; moreover as a rule a woman completes her growth some years earlier than a man. The bones are lighter in the woman than in the man; not absolutely but in proportion to the weight of the body. They are, it is stated, not merely thinner but more fragile. The difference may be traced even to their chemical composition. The whole muscular development is inferior in woman to that in man by about one-third. The heart in woman is smaller and lighter than in man—being about 10½ oz. in man as against slightly over 8 oz. in woman. In the woman the respiratory organs show less chest and lung capacity. Again, the blood contains a considerably less proportion of red to white corpuscles. Finally, we come to
