A China STATERA, in the form of a Steel-Yard. The 
Chinefes carry it about them, to weigh their Gems, and 
the like. The Beam or Tard is of Wood, round, l of an 
inch over, and a foot in length. Upon it are Three Rules 
of Meafure, made of fine Silver-Jludded Work., as in 
Watch-Cafes. One of the Rules is divided into inches 5 and 
every inch into (25) equal parts. The other Two are alfo 
divided into equal parts 3 but not into inches. They all 
begin from the end of the Beam: whence, the. Firft is ex¬ 
tended (8) inches 3 the Second, 6;; the Third, 8 The 
firft, is our Europe- Meafure 3 the other two, I take to be 
the Chi -Meafure,and that of fomc other Country trading 
with them. 
At the other end of the /Ay/ hangs a round Scale , mark¬ 
ed with a fquare Seal of China- Characters. At Three feve- 
ral Diftances from this end, are fallen d fo many flender 
firings. The Firft Diftance makes l ths of an inch 5 the 
Second, is double to the Firft, or an inch and 3 the Third, 
two inches and 
When they weigh any thing, they hold up the Yard by 
forne one of thefe three firings, and fo hang a fealed weight 
(about an Ounce and '* Troy-weight) upon forne point of the 
Rule , as the Tiling requires.. ’Tis kept in a Cafe fitted to it, 
alrnofl like a Dancing-Mafier’s Kit. There is one like to this 
in the Mufaeum Romanum. (a) (a) P.34.
