As has already been stated, when it is desired tomeasure velocities directly, two targets must be setup 50 meters apart. The chronometer circuit passesthrough the first, and the registrar through the sec-ond, the disjunctor being in both. Should local diffi-culties intervene to prevent the targets being set upexactly 50 meters apart, multiply the velocity read , from tue scale by the constant ratio —where D is the 50actual space in meters. For transport, the diflferentparts of the instrument are packed in a box, which The currents befng properly established and suffi-ciently strong to enable the magnets to maintain therod-armatures, the next step is the adjustment ofthe apparatus, which comprises thes
