AFTER A BRIEF REVIEW OF THE MATHEMATICAL THEORY OF THE RESISTANCE OF A FLAT PLATE TO A CURRENT OF MOVING AIR, AND REFERENCE TO THREE PREVIOUS SERIES OF AIR RESISTANCE MEASUREMENTS, A DESCRIPTION IS GIVEN OF THE EXPERIMENTS ON DETERMINATION OF AIR RESISTANCE BY COASTING DOWN A HILL OF UNIFORM GRADE CONDUCTED AT YALE UNIVERSITY DURING 1928. THE COASTING TESTS REPORTED SEEM TO INDICATE THAT EACH TYPE OF CAR BODY HAS ITS OWN CHARACTERISTIC COEFFICIENT IN THE AIR RESISTANCE FORMULA AND THAT EACH ROAD MAY HAVE ITS INFLUENCE IN MODIFYING THE AIR RESISTANCE.
