Mr. Drererict!) to repeat his experiments once mare, now making 
use of an aneroid which could give a deviation not to one side 
only as before, but to both sides. As changes of temperature exer- 
cise a great influence on the zero position of the aneroid, it was 
placed in a waterbath. After having determined the constant of this 
aneroid, he repeated his observation and obtained the following 
results. 
To facilitate comparison I shall again add some of my results.
