weighty 23 Grains and One-fourth. Prom whence 
the Averdupois ‘Pounds deduced equal to 6998.35 
of fuch Grains as the Troy Ounce is reputed to con- 
tain 480 of; and the Averdupois Ounce , of which 
1 6 are fuppofed to make a Pound, is found equal to 
437-4 like Grains. 
Again : The Seven Pound Bell Averdupois Weight, 
with the fame Scales, and upon a Medium of Four 
like Experiments, counterchanging, as before, both 
Weights and Bafons, was found to be countcrpoifcd 
by 102 Troy Ounces One Penny-weighty and 21 
Grains. According to which, the Averdupois Pound 
comes out equal 107000.7, and the Ounce to 437.54 
Troy Grains. 
Again : The Engle Bell Averdupois Pound, with 
the lefier Scales, on the Medium of Two Experi- 
ments, counterchanging the Weights, the Bafons not 
being moveable, was found to weigh 14 Troy Ounces 
1 1 P enny-weight and 1 8 Grains ; or was equal in 
Weight to 7002, and the Ounce to 437.62 Troy 
Grains. 
The Engle Averdupois Bell Pound, again ft the flat 
Averdupois Pound Weight, was found, on a Medium 
of Two like Experiments, to be heavier by Two Troy 
Grains and a half: Whence the flat Averdupois Angle 
Pound Weight weighs only 6999.5, and the Ounce 
437.46 Troy Grains. 
The Royal Society's Averdupois Pound was, i*. 
like manner, found to be lighter than the Exchequer 
Engle Bell Pound Weight, by One Grain. 
And their Troy Pound Weight to be lighter than 
the Eight and Four Ounce Troy Weights at the Ex - 
chequer , taken together, by half a Grain .
