The proportion given by this Author as the true 
one of the Averdupois Pound to the Troy Pound is, 
that fourteen of the former are equal to feventeen 
of the latter. 
From whence the Averdupois Pound would be 
found equal to 695>4.28y, and the Ounce to 437. H 3 
Troy Grains i which is indeed a little lefs than the 
fame have hnce been determined by others 5 for 
Mr. Ward oiCheJler gives from a very nice expe- 
riment as he calls it, of his own, that one pound 
Averdupois was equal to 14 ounces 11 peny weight 
and if! Troy Grains , or to 6999!, and confe- 
quently the ounce Averdupois to 43747 the 
fame grains. And feveral Gentlemen of the Royal 
Society , who very carefully on 22 April 1743. exa- 
mined the original flandards of weights kept in the 
Chamberlain's Office of his Majesty’s Exchequer, 
found, upon the medium of the feveral trials which 
they made with thofe flandards, that the Round 
Averdupois was equal to 7000.14, and the Ounce 
Averdupois to 43 74 1 Troy Grains . Rhil. TranJ

ning, which I here tranferibe, with an account of 
fomc of their ufes, in his own words.
