bullet-mold can be made, so that six or 

 seven excrescences, or ribs, project from 

 the sides of the ball ; then put this ball, 

 with a greasy patch, into a smooth-bored 

 gun, of a perfect caliber; the author will 

 be entitled to shoot as true, with this smooth- 

 bored gun, as he can with a rifle-gun, pro- 

 vided, as the author asserts, that the ball 

 takes a spiral rotatory motion round its 

 axis, by the action of the air on the excrescences 

 of the ball, and not from the grooves in the 

 rijle. 



One observation more. It is respecting 

 balls cast for rifle-guns. The author says, 

 you should always put that part of the ball, 

 where is the neck, which is formed by the 

 mold and cut off, uppermost, I widely dif- 

 fer with him: the reverse, or smoothest 

 part of the ball, should be placed upper- 

 most ; for, when no inequality in the ball is 

 opposed to the air, in the flight of the ball 

 through the air, the ball is less liable to de- 

 viate from its direction. 



I shall now have done with rifle-shooting, 

 and with any further observations on this 

 gentleman's work; candidly acknowledg-
