According to theory, if lines were drawn parallel to the 

 directions cf a ship's course, the wind, and the sails respect- 

 ively, so as to form a triangle, a circle being drawn round 

 the triangle, the ship ought to arrive at any part of the 

 circle in an equal time. But the fact is far otherwise. 

 Robison. 



The lee way is found to remain nearly the Same in various 

 directions of the wind. Robison. 



When the sails are taken in, the ship is found to have a 

 tendency to turn her head to the wind. Robison. 



Greasing a ship's bottom is supposed to lessen the fric- 

 tion, and the experiments of the society for naval architec- 

 ture show, that a watersoaked plank is more resisted than a 

 dry one. Coulomb however found little or no effect from 

 oiling or grcjising wood.

Considers the inclination of a body when equal to a given 

 angle, and not as evanescent ; siiows by the example of a 

 square beam, that the effect of a finite inclination must in 

 practice be of consequence ; examines the actual stability 

 of various forms in different circumstances, and applies the
