The following experiments N° 78, 79, 80, and 81. were 
made in hopes of being able to dilcover a method of adding to 
the force of gun-powder. Twenty grains of the fubftances 
mentioned in the remarks upon each experiment were inti- 
mately mixed with the powder of the charge. In the experi- 
ment N° 82. a large wad of tow, well foaked in etherial Jfpirit 
of turpentine, was put into the piece immediately upon the 
bullet : and in the experiment N° 83. a wad, foaked in alkohol, 
was put into the piece in like manner.
