The first and second of these experiments were performed by placing two 

 fog signals on the I'ails at O and 0", distant from each other 100 feet, and mea- 

 suring with a chronograph the interval of time between the explosions, as re- 

 gistered in the first column ; the remaining experiments were performed with 

 one fog signal placed at 0, the time of the front wheel passing O" being ob- 

 served by sight. The waggon was impelled by a number of men, who ceased 

 pushing it before its arrival at 0".
