respecting the Observatory at Benares. 
height of 10 feet and 10 inches from the base, are fixed two 
iron pins, each forming a centre, from which circular lines 
are drawn, intersecting each other, as in the annexed repre- 
sentation ; 
with a parallel line drawn underneath, which has the hour, 
or gurry and pull lines marked on it. The wall is plastered ; 
and there are, on other edifices fronting the east, similar lines 
drawn ; the use of which, I understood, was to ascertain the 
time of the day. 
B. An equinoctial dial, called gentu-raje . — It is a circular 
stone, fronting north and south, but inclining towards the 
south. The diameter of the south face is 2 feet inches, a per- 
pendicular line falling from the top will give one foot distance 
from the bottom of the inclined plane. In the south front of 
this stands a small stone pillar, distance 3 feet 8 inches ; a 
line drawn from the centre of this dial to the point on the top 
of the pillar, will, by its shadow, give the time of the day. 
On the nadir side of this dial, the stone is 4 feet 7 inches 
diameter ; on the centre of which is a small iron stile, with 
a hole in it, perpendicular to its plane ; and in the perpendi- 
cular line of the chord are placed two small irons. A line 
passing through the hole in the stile, and each end applied 
to the forementioned irons, gives a shadow, which denotes the 
hour, &c. 
C. A brass circle in the line of the equator, facing north
