Table (2). — Calculated Results. 



The quantities here tabulated are the same as in the first series of experi- 

 ments ; and in calculating v' for Exp. 5, the same method was followed as in 

 Exp. 6 of first series. 



Third Series. 



February 23, 1850. — Fine day. 

 Weights of waggon and sledge same as before. 



The mode of estimating the velocity on this day was to allow the waggon 

 to run down the inclined plane a measured distance, and thence compute the 

 velocity of the impact.
