To dye cloths of an Amua-sabz, or mangoe-green color. 
The cloths require first to be dyed in a solution of indigo; the latter to be 
used at the rate of two chitaks on an average per piece. Afterwards they must be 
boiled in water with a mixture of rind of pomegranate init. In this operation, half 
a seer of the lattershould be mixed for each piece. They are then to be steeped ina 
strong solution of water and alum, which should be given in two chitaks on an 
average. After this, a preparation of two chitaks of turmeric dissolved in water 
should be made, and the stuffs kept dipped in the same for one whole night. 
In the morning following, they must be washed in clear water, and lastly dyed with 
the juice of Késwm flower, which when first extracted is naturally yellow, and 
which is termed ‘‘ Pin’ in Hindustani. They are afterwards to be folded and 
beaten smooth. 
The dyeing of Staj Pakht, a red yellow—the color of a bird so called. 
A composition comprising ten seers of oil of eastor, five seers of impure 
soda, (khdk-i-zamtn-i-shér) one seer of goat’s dung; to be made, and to be all 
dissolved in a sufficient quantity of water. Twenty pieces of stuff are then 
to be washed in pure water, in a vessel all separately, and one by one, chang- 
ing the water every time. This operation is to be kept in continuance for fifteen 
days. They must afterwards be washed in clear water, and soaked in a solution 
of alum and water. Twenty-five seers of powder of A/ should then be dissolved 
in a necessary quantity of water, in a large vessel, and the cloths steeped and co- 
loured in the liquor. They are thus to be wrought up for the space of six days, 
and finally dried and folded. 
4.—Note on Lieut. Burt’s instrument for trisecting Angles. 
On reading the papers on the trisection of angles, in the number for November 
last, I observed some inaccuracies, which as they were overlooked in the last num- 
ber, I now beg leave to bring to notice. 
Mr. Burt, in proving the correctness of the instrument, has made the truth of 
the demonstration depend on a position which is itself in want of proof. He says, 
(page 500, 1. 8), “‘ rad. bo-rad. ao,’’ but they are not necessarily equal from the 
construction, and it should therefore be proved that the locus of the point 4 is in 
the arc abe. The demonstration is consequently faulty. I think however the in- 
strument will effect the purpose intended ; and perhaps when I have more leisure, 
I may attempt to prove its accuracy, if not anticipated by some one whose avoca- 
tions are more in accordance with such pursuits. Mr. B. says that A B the fourth 
leg of the instrument, may be dispensed with. I do not think it can, but I don’t 
understand this part of the paper, nor do I see how a line can be parallel to one or 
two others, and also pass through the same point with them. 
I have not tried to construct the instrument, but I should anticipate some difficulty 
in applying it, as one may not readily know when the points A and O respectively 
coincide with a and o,
