ABSTRACT DR. HAROLD JEFFREYS, in his letter appearing in NATURE of Aug. 11, p. 206, mentions some interesting practical effects for which the principle to which it refers is responsible. To
those which he mentioned may be added a physiological consequence for the circulation of the blood. As the blood-stream races past the cusps of the valves at the orifices of the heart, some
of the eddies, to quote his words, “enter the dead water, where they produce a circulation with a reverse current” behind each valve. This disposition prevents extreme eversion of the valve,
and facilitates closure of the valve without delay or hindrance so soon as the diastolic check of the stream current ensues, at end of the active beat. The anatomical channel is actually
bayed out (sinus of Valsalva) in the case of the two largest blood-vessels, in order to favour development of what in the letter is termed the second row of vortices. SIMILAR CONTENT BEING
