186 MEASUREMENT OF AJT ARC ON THE 



west from eacli other; and the following triangles 

 have been made use of to obtain that distance. 



Distance, Carangooly /)ww Permacoil 1342S6,4. 



The distance from Curnatighur to Maillacherrif 

 has also been brought out from a northern series 

 of triangles derived from the side of Poonauk hill 

 and Maumdoor hill, of the great triangle Maum- 

 daoTy Poonauk, and Mullapode hill : the triangles 

 are Poonauk, Maumdoor and Hanandamulla ; Ha- 

 jumdamidla, Maumdoor, and Telloor ; Telloor, Ha- 

 vMndamulla and Curnatighur ; Curnatighur, 2el- 

 loor and Maiilacherri/ Droog. Upon the distance 

 from Curnatighur to Alailiacheny as a base, the 

 distance from Curnatighur to Carangooly has been 

 computed, and differs only two feet from that 

 derived from the side Carangooly and Maillacherry 

 Droog : but there was some variation in the angles 

 taken at Poonauk hill, which renders it doubtful, 

 for the present, which to select; I have therefore 

 relied on the single distance given in the thirty- 

 fourth triangle.
