In the last experiment the vessel had been lightened, so as to draw only 2 inches, 

 and retained only one individual, who executed the duties both of directing the 

 vessel, and observing the gauges of immersion. It was not found practicable to 

 obsei"ve the oscillations of a moving force so impetuous. 



The experiments which have been given, afford the means of estimating the
