Only in part shown in curve. A very 
small easterly torque was applied five 
minutes before making contact. The 
experiment is made during a steady 
motion eastward, which becomes re- 
versed to a marked westerly accelera- 
tion beginning one minute after contact. 
The beam then travels 125 to westward, 
and remains against stop as observed 
for one minute when experiment was 
terminated, as errors of temperature 
would now be probable.
