1. The Experiments here prapofed, are to be made in Guns 
of all Sizes l Bores , Weights, Metals , &c. 
2. Three or more Shot to be made with every different Charge, 
and at every feveral tryal, that the certainty may the better ap- 
pear. 
j$. The firft Shot being Meafured and marked, the reft may 
all be Meafured from it, or from one another, to fave labour. 
4. The Gun is to be pointed, placed, and ordered every time, 
in one and the fame place and pofition, aiming ftill at the fame 
Mark, or pointing ftill in the very fame Line or Azimuth j that 
fo all the Shot may fall in the fame Line, as near as is pofiible. - 
5. The Powder muft be exactly weigh'd, every time the Peece 
is charged , left it having been weigh’d long before, the weight 
may be alter'd $ though Experiment may be made with Car-- 
trid ges and without. 
6. The Powder and Bullet is to be rammed home equally at 
etieryShot 5 though the loofer the Powder lye, it fire the better. 
7. When the right Charge of a Peece is found, that makes the 
fartheftShotin the ordinary and plain way of Charging, IVJon- 
iiem de Sous contrivance of a Wedge may be tryed, to make is 
Shoot farther 5 which is a piece of Board, fo long, as being thruft 
home to the Breech of the Peece at one end, the other may reach 
farther out than the outfide of the Bullet , being ramm’d up to 
its place 5 broad about an Inch, and thin fo far as the Wadd be- 
fore the Bullet reaches on the out-fide ^ there it is to have a 
Shoulder, from which forward to the end, it is to be cut a floap 
like a Wedge, being of fuch thicknefs,as that at the place, where 
the Center of the Bullet is to be, it may make it ftick fofaft, 
that the Powder finding more reiiftance may at length drive it 
out with the greater violence* 
8 . Another of this nature is a WoodevrTampio^^ like a piece 
of a Cylinder , big enough to fill the hollow Cylinder of the 
Gun, the length fomewhat more than the Diameter of it and 
hollow’d towards the Bullet, fo as to fit it 5' and either flat, or 
(which is better) hollow like wife towards the Powder, and fcr- 
ving inftead of a Wadd, Thefe and fuch others will probably ren- 
der the effect of the Powder greater, than other wife it would be* 
Cj. The Strength of the Powder muft be examin’d by a Powder » 
Tryer 0 that raifeth a Weight, fuchan one as has been contrived 
by Mr. Hoo 4 ^ and is made by Mr. shortgrave , Operator to the 
Roy d Society* " > j 10. 1 fee
