292 ACCOUNT OF TRIGONOMETRICAt 



ghauts, and through the whole extent from Fort St, 

 George to Mangalore, being a distance of three hun- 

 dred and sixty two miles and upwards, on the parallel 

 of the mean latitude between these two places. 



In the triangles of 1 803, a great distance was deter- 

 mined between Carangooly and Carnatighiir, at which 

 stations pole-star observations were made for deter- 

 mining the difference of longitude of those two places, 

 and it was then thought probable that others might 

 be found in succession, nearly Avest from Carnatighur, 

 so as to afford great distances for connecting the me- 

 ridian lines ; but it was afterwards discovered that 

 Kylasghur was preferable, and it was accordingly 

 chosen for continuing those distances to the west- 

 ward, that between Carangooly and Carnatighur, as 

 already determined in 1803, remaining the first. 



Kylasghur was laid down from the side Carnati- 

 ghur and HanandamuUa, being given in the 39th tri- 

 angle, and the side HanandamuUa and Poonauk of 

 the 21st triangle, was the base for finding the dis-^ 

 tance of Poonauk from Pilloor hill. From this last, 

 and from the side Kylasghur and HanandamuUa, 

 each as a base, the side Kylasghur and Pilloor hill has 

 been obtained as a mean of the two results. From 

 this, as a base, the series has been carried on to Yer- 

 racondah and Kylasghur, depending on the measured 

 line near St. Thomas's Mount ; the particulars of 

 which have already been given in the 8th Vol. of the 

 Researches. 



The base near Bangalore (an account of which is 

 given in Art. 2) is then had recourse to, for bringing 

 out the same distance, and it will appear, in the ar- 

 rangement of the triangles depending on that ba^e,
