APPENDIX. 91 



In the arc north of Putchapolliam } there were three stations of obser- 

 vation, besides the station at Putchapolliam > viz. Dodagoontah> in latitude 

 i'3° nearly, at Bomasundrum, which is nearly i4°j and at Paughur, which 

 is upwards of 14 6.

The celestial Arc between Putchapolliam rand Dodagovntah was .2 9.73 - 

 Between Putchapolliam and Bomasundrum was...- ,-..3 1.88 

 Between Putchapolliam and Paughur was ...... ._.„/,,3 6 37.78 



And if to each of these we add 2 50 10.54 which is the celestial arc 

 between Punnae and Putchapolliam , we shall have the three following 

 arcs, viz. 



Punnae and Uodagoontah .......... «..»..-»—■ = *. .4 50 20r3fr 



' Punnae and Bomasundrum 5 50 \%A% 



Punnae and Paughur ........5 56 48.32 



The former terestrial arcs were as follows, viz. 



Between Putchapolliam and Dodagoontah. 727334.6 Feet. 



Between Putchapolliam and Bomasundrum 1088275. & 



Between Putchapolliam and Paughur.... 1128472, 



Hence, by adding to each of these 1029 100:5 feet/ we shall have the 

 three terestrial arcs as follows, viz. 



Feet. Fathoms. 



Punnae and Dodagoontah,..,. ..: 1756435.1 or 292739.2 



Punnae and Bomasundrum, 2117376.3 or 



Punnae and Paughur, 215772.5 or 359595.4 



Hence, by comparing the respective arcs, we shall have the mea-n 

 length of the degree due to the latitudes of their respective middle points, 

 as follows :
