Finds, that at the moment that one of the floatboards is 

 vertical, their number is indifferent to the effect ; but that 

 at other times, the number 6, 9, or 30, has an advan-tage, 

 accordingly as the (xisition is more or less remote from a 

 vertical one.

Observes, that the number of floatboards impelled being 

 proportional to the velocity of the vf heel, the relative velo- 

 city ought for this reason to be half cf the absolute velocity 

 for the greatest effect. But the time oi action on each float- 

 board being as much smaller as their luimber is greater, this 

 consideration cannot in any degree afTcct the calculation.
