To
determine the value of any string or bunch of pearls, any string is
selected and cut from the bunch with as little spare silk as possible;
this is weighed very nicely by an Indian weight called Manjelin, 20 of
which make I Collinjee.
The
relative values of pearls are in proportion to the squares of their
weights, according to which the chour is always calculated from the
standard of I pearl weighing 1 Manjelin being nearly equal to i of a
chour.
Pearls
are distinguished by the sieve or searse through which they have
passed, and by the number of such which will weigh a Collinjee. Thus a
certain sieve will pass pearls of a manjelin each precisely, and this
may be called 20 sieve.
I pearl of 20 sieve is equal to f chour sieve and I collinjee is equal to
