Tome Months fince publifhed by Order of the Council 
of the Society in thefe Tranfaffions * : It was nor at 
all the Intention of the Society, to determine what 
was the abfolute legal Length of the Tard , or the 
real and legal Weight of the faid feveral ‘Pounds ; but 
Only to lodge and preferve, in thofc refpe&ive Places, 
Two Meafurcs, and Two Sets of thofe Weights, 
fufficiently near to what were in common Ufe, and 
well agreeing with each other, for the Purpofe of 
comparing together, by fome certain Standard, to 
which recourfe might be had in either Kingdom, the 
Succefs of fuch Experiments made either in England 
or in France , in which Mcafure or Weight might 
particularly be concerned. 
And for the fame Reafon, the Gentlemen of the 
Royal Academy of Sciences , were plcafed to take 
care to have the Length of their Half-Toife fet off 
on both the Brafs Rods, upon which the Englifh 
Tard had been already laid off, and to provide Two 
Brafs Weights of Two French Marcs each j one of 
which was fent over hither, when one of the Brafs 
Rods, juft mentioned, was again returned over to 
the Society. And it was the Proportion only 
between Thefe feveral Standards, that was propofed 
to be laid down in the faid Paper publifhed in thefe 
Tranfaffiions ; without intending thereby to afeertain 
the juft and legal Proportions between the Weights 
and Meafures of both Nations. Though it is not to 
be doubted, but that this Meafure of the French Half- 
Toife , and the French Two Marc Weight, are, like 
the Englifh , fufficiently agreable to what are there 
conftantiy ufed.
