the Moon relative to the Sun during the time, 
which is equal to the square root of the difference of 
the squares of the difference of the radii of the 
Shadow and the Moon, and of the Latitude of the 
Moon. pe 
(e) If from the time giving the end of the tithi, the time 
as obtained by (c) is deducted, we get the commence- 
ment of the eclipse ; if it is added, we get the time 
of the end of the eclipse. If the time as obtained 
by (d) is deducted we get the commencement of total 
eclipse : if it is added, we get the end of the total 
eclipse. 
(6) In the case of the Solar Eclipse the radii of the Sun and 
the Moon seem to have been taken as 15’ and 18’. The process 
from (1) to (4) is the same as before. Then the following 
corrections should be introduced :— 
(a) The time of the end of the tithi is to be corrected for 
Parallax in Hour Angle. The day being divided 
into 8 parts, the following are the corrections, sub- 
tractive in the first four parts and additive in the 
last four

(6) The latitude of the Moon as obtained in (4) is to be 
corrected for Parallax in Latitude. The corrections 
are as follows:—

When the latitude as obtined in (4) and the parallax in 
latitude are both North or both South, they are to be added ; 
but when one is North and the other South the difference is 
to be taken. 
I shall conclude this by a few examples. I take this op- 
portunity of expressing my indebtedness to Prof. Ashutosh 
ae M.A., of the Vidyasagar College for many valuable 
ints.
