(99.) If mental action is electric, the proverbial quickness of 

 thought that is, the quickness of the transmission of sensation and 

 will may be presumed to have been brought to an exact measure- 

 ment. The speed of light has long been known to be about 192,000 

 miles per second, and the experiments of Professor Wheatstone have 

 shown that the electric agent travels (if I may so speak) at the same 

 rate, thus showing a likelihood that one law rules the movements of 

 all the " imponderable bodies." Mental action may accordingly be 

 presumed to have a rapidity equal to one hundred and ninety-two
