The first nic was made. by simply trying to beat time 
with the index finger of the right band to signals given on the 
back of the left hand. Great care was taken to prevent any 
idea of the time belle received except through the nerves expert- 
mented upon. On examining the register after the first set of 
observations was oh it was found that the answers some- 
times followed and sometimes preceded the signals and did not 
have the regularity expected. Upon noticing that the signal 
had been frequently Shusieeiad I made a_ new effort, taking 
_ great pains tobe sure that the signal was elt each time before 
answering. A few observations were then taken, and after 
stopping a short time to examine the effect, a few more were 
taken. The following was the result, the tuning-fork making
