Frame, and difeharging it feveral times with and With- 
out Ball , fome Powder was always collected, but 
mixed with a great deal of Dirt. 
It is however to be obferved, that in Two Experi- 
ments made the 22d of July , near the Artillery- 
Ground, before the Prcfident and fome of the Fellows 
of the Society, with a finer fort of Powder, in a 
Barrel of Three Feet Nine Inches in Length, and 
Three- fourths of an Inch Bore, with Twelve Penny- 
weight of Powder the Firft time, and Twenty- four 
Penny-weight the Second time, without Ball or 
Wadding, no Powder could be found fcattered on 
the Paper laid before the Piece, nor (licking to a 
Board at the Diftance of. about Ten Feet, againft 
which the Piece was pointed. But when the fame 
Powder was fired in a fhort Barrel of Five Inches Two- 
tenths of an Inch in the Chace, either with or without 
Ball, fome Quantity of Powder was always colle&ed. 
Other Experiments were afterwards made before 
the Committee, by firing a Fowling-piece charged 
with Five Penny-weight of Powder, againft a Sheet 
of whited-brown Paper, at the Diftance of Two or 
Three Yards ; the Paper was found pierced with fe- 
veral Hundred Holes, and the Jags of the Paper ap- 
peared on the Backfide. In a fecond Trial with Ten 
Penny-weight, the Paper had more Holes in it. A 
third Trial was made with Five Penny-weight of 
Powder and Ball, and then few Holes appeared in the 
Paper. In a fourth Experiment made with a fhort 
Screw-barrel Piftol, with a Charge of One Penny- 
, weight two Grains of Powder and a Ball, feveral 
Holes were found in the Paper *. 
* That the Paper in thefe Experiments was pierced by the unfired 
Powder, appears, becaufe feveral Grains were found lying behind the 
Frame, to which the Paper was fixed, and fome few Iluck in the Paper.
