‎First edition of this classic in hydrodynamics and giving the first measurement of the velocity of the pulse.""In 1821, assisted by his brother Wilhelm, (then only seventeen years old and preparing for his university entrance examination) Weber began a long physical study of the flow and the progress of waves in fluids, particularly in elastic tubes. In their Wellenlehre (1825) they formulated the basic laws of hydrodynamics and were the first to apply that branch of physics to the circulation of the blood."" (DSB).Garrison & Morton, 766. - ‎
