With the view of obtaining profoiles to become such straight lines, as test curves of the current meters pass through the origin, the author has made flat plates and circular arc aerofoiles having many kinds of cambers, and tested. When these tests are compared with each other, inverse circular arc aerofoiles is excellent. Results obtained are as follows : I. The starting velocity υ_0 of the current meter increases as the resistance torque increases, and therefore, to make υ_0 smaller the resistance torque of the device must be reduced as far as possible. II. The author has made circular arc aerofoiles having many kinds of cambers, tested, and compared them, and he has made the inverse circular arc aerofoiles, and the test curve of the current meters became a straight line, extension of which nearly passes through the origin.
