The laft Experiments were made with T weive Penny- 
weight Charge and Ball, as before ; the Quantities of 
Powder collected fromTwo Difcharges were refpedive- 
ly, Two Grains ; and Four Grains and an half. The 
Frame being broke, a third Experiment could not be 
made. 
The Powder colleded after the feveral Difcharges, 
was put into feparate Boxes ; it feemed much bruifed, 
and mixed with Dirt. Yet feveral of the Parcels be- 
ing tried, fired with brisk Explofions; and fome of the 
Powder collected from the Experiments with the fhort 
Barrel, amounting to Six Penny-weight Sixteen 
Grains, being put into the long Barrel, and fired with 
Ball, went off with a ftrong Report; and the Ball 
pierced the Deal- board, at the End of the Frame, and 
penetrated Two Inches deep into an Elm-plank placed 
to receive the Balls. 
Some Gentlemen, prefent at thefe Experiments,

with Twelve Penny- weight of Powder and Ball, as 
before ; through a very large Funnel, the Quantities 
found, after Three Difcharges, were feverally, One

lengthening the Piece. 
Some Experiments were alfo made with the fhort Bar-
