(a.) The Country Wells.
The effect of the variations of the barometer previously recorded (1) were found again in every record made during the present series of
observations, but were differently developed in different wells. The Lincoln College well (344 ft.) rises four times as much as the barometer falls, but a near-by well of 60 ft. in depth showed a water-rise only equal to the barometer-fall. A typical week's graph for this well is reproduced (fig. 2), the well reading being inverted.
