Experiments upon Gunpowder. 



21 



The following experiments, Nos. 78, 79, 80, and 81, 

 were made in hopes of being able to discover a method 

 of adding to the force of gunpowder, twenty grains 

 of the substances mentioned in the remarks upon each 

 experiment were intimately mixed with the powder of 

 the charge. In the experiment No. 82 a large wad of 

 tow, well soaked in ethereal spirit of turpentine, was 

 put into the piece immediately upon the bullet; and in 

 the experiment No. 83 a wad, soaked in alkohol, was 

 put into the piece in like manner. 



In the nine following experiments, viz. from No. 

 84 to No. 92, inclusive, the valve-vent was made use 

 of, and the bullets were made to fit the bore of the 

 piece very exactly by means of oiled leather, which was 

 so firmly fastened about them that in each experiment 

 it entered the target with the bullet.
