to the Great Meridional Arc , &c. 33 
21 0 6', having just returned from finishing it ; and when all 
the necessary calculations and corrections are made, I shall 
draw out an account of the whole, and forward it to the Royal 
Society at a future period. The celestial arc has been de- 
termined by seven stars, but there are many now out of my 
reach, which I observed in the beginning. 
It may be satisfactory to the mathematicians in Europe to 
know, that I am now advancing through Hindoostan ; and, 
from what I can learn from the different publick authorities, 
I do not apprehend any difficulty. They are all inviting in 
their letters, and all seem desirous that I should go through 
their respective districts. If my present arc be continued 
direct, it will pass through Bopaul, and near Seronje, where 
I shall have again to observe the stars and measure a base ; 
and if Scindiah’s country be in a quiet state, my meridian will 
pass near Gualior, his capital ; and my sixth section will 
terminate near Agra, on the Jumna. I have made up my 
mind to execute all this if I live, and continue to have that 
flow of health and spirits which have hitherto attended me. 
The results of such an extensive measurement must be in- 
teresting to scientific men ; and I shall exert my endeavours 
in doing justice to the work, and in giving a faithful account 
of the operations.
