Found by trial that the quantity 24 ¢c.c. of liquid took just 60 seconds to flow 
from above into the lower vessel. It is evident, therefore, from the curve, that 
it was just as the transfer of the liquid was completed that the easterly motion 
of the load turned to a westerly motion, which continued during the time of 
observation.

Close examination of the curve shows that the swing to westward which was 
coming to an end at the moment of the experiment, has apparently been rather 
abruptly terminated, and a period of delay substituted retaining the load at its 
westerly deflection before the return swing eastward properly begins. The 
interference with the normal vibration is only such as would arise from a very 
feeble force restraining the motion of the beam during the fall of the liquid, and 
for some sixty seconds after. A preponderating direction can hardly be ascribed 
to the force.
