“Kew Instruments arranged in the relative positions recommended by Lloyd so as magnetically to interfere with one another as little as possible. We are supposed to be viewing the whole from the south. No. 1 to the right is the declination instrument, No. 2 that for the horizontal force, and No. 3 in the distance behind the central pillar (No. 4) the vertical force magnetometer.” —The Encyclopedia Britannica, 1903
