Vol. XT, No. 1.) The Weighing Beam called Bisa danga. lt 
[N.8.] 
of split bamboo suspended by means of strings through the holes 
near these narrow ends already mentioned; the pans are gene- 
rally coated with clay or some other suitable coating material to 
make them smooth, and at the same time to load them 
conveniently and sufficiently to make them equal in weight 
to the standard pan with reference to which the scale is 
year. They are marked A an or reference. Both are 
made of Sal wood (Shorea robusta) which is heavy and strong. 
The beam marked A is 588 cm. in length, round and 
gradually tapering from diameter 3-2 cm. on the broad end 
which (for the position of the beam in weighing) we may also 
call as the left end, to diameter 2 cm. on the narrow end 
which is also the right-hand end. The hole through which 
a loop of string hangs for the suspension of the pan is close 
to and is only 5 cm. from the narrow end. 
end. The scale consists of 17 ring marks, i.e. circular thin 
grooves at right angles to the length (axis) of the beam, 
in the scale at which it brings the beam at a horizontal posi- 
tion, indicates the weight of the article in the pan. 
of. the beam marked B is 55°5 em. This is 
also roughly rounded (i.e. not turned in a lathe) and is 
gradually tapering from diameter 3:3 cm. on the left end to 
2 cm. in the narrow right-hand end. The pan is suspended 
by means of a looped string passed through a hole which is 
4°8 cm. from the narrow end. e scale begins at 33-5 
rings, as in the other beam marked A, are marked on the 
top side with cross marks (x ) deeply inscribed signifying their 
importance over the rest of the scale. 
n comparison of the two beams bought at Rambha, it 
is clear that no uniformity as to size of beam or of scale is 
observed. Beams are prepared in the ordinary way, and the 
scale is inscribed, a known quantity of weights in the pan being 
suspended. The correct position of the sliding loop on the 
beam being indicated by marks, which are inscribed when the 
am assumes a perfectly horizontal position for each weight.
