Enquire within upon everything

In this attempt you will find that the water buoys you up against your inclination; that it is not so easy to sink as you imagine, and that you cannot, but by active force, get down to the egg. Thus you feel the power of water to support you, and learn to confide in that power, while your endeavours to overcome it, and reach the egg, teach you the manner of acting on the water with your feet and hands, which action is afterwards used in swimming to support your head higher above the water, or to go forward through it. 1399. continued... "I would the more earnestly press you to the trial of this method, because I think I shall satisfy you that your body is lighter than water, and that you might float in it a long time with your mouth free for breathing, if you would put yourself into a proper posture, and would be still, and forbear struggling; yet, till you have obtained this experimental confidence in the water, I cannot depend upon your having the necessary presence of mind to recollect the posture, and the directions I gave you relating to it. The surprise may put all out of your mind. 1400. continued... "Though the legs, arms, and head of a human body, being solid parts, are specifically somewhat heavier than fresh water, as the trunk, particularly the upper part, from its hollowness, is so much lighter than water, so the whole of the body, taken altogether, is too light to sink wholly under water, but some part will remain above until the lungs become filled with water, which happens when a person, in the fright, attempts breathing while the mouth and nostrils are under water.
