## Abstract The instrument described gives a continuous record on photographic paper of the change in weight of a naturally exposed grass surface, 330 cm^2^ in area. The sensitivity is 2 mg cm^−1^ per cm of record and the time scale is 0.5 hr/cm. Observations suggest that on very calm nights the co
A device for automation of both the simple and the differential magnetic diver balance is described. By using a mechanically chopped laser beam and doublebeam system, a large proportional sensitivity of the controller and considerable stability over a relatively long period of time were attained. Th
