 ball is moved before all that is fired takes effect ; and that 

 " the longest chamber is the most efficacious.

Hutton on the force of fired gunpowder. Ph. 



tr. 1778. 50. 



The powder appears to fire almost instantaneously, for 

 the force is nearly in the direct proportion of the powder, 

 the velocity in its subduplicate ratio, and in the subdupli- 

 cate ratio of the ball inversely. The height and the range 

 a^e therefore at the weight of powder.
