558 ACCOUNT OF TRIGONOMETRICAL 



Fort St. George, we get 5° 27' 45" for the difference 

 of longitude between the steeple in Fort St. George 

 and the flag-staff at Mmigalore, 



The meridians of Cara7igooly and Balroyndroog arc 

 also used for fixing the latitudes and longitudes of 

 other places on the two coasts, as will be seen in the 

 detailed account (Art. li); so that by having the 

 positions of a few places accurately laid, the general 

 form of the peninsula may be determined, and a foun- 

 dation laid for carrying on more minute surveys, both 

 along the coasts, and in the interior. I have given 

 here the mode of computing the positions of -the most 

 remarkable places on the coasts, and of the great 

 stations connecting the meridian lines. But from 

 these different meridians, the latitudes and longi- 

 tudes of other places are fixed by using the eastings 

 and westings, and the northing and southing from the 

 great stations, and computing spherically ; so that 

 the whole together amount to near six hundred. I 

 have subjoined to this paper an alphabetical list, 

 which includes the most remarkable places within the 

 extent of the survey; and I have also added a table, 

 giving the perpendicular height of all the great sta- 

 tions above the level of tlie sea, and the ultimate 

 comparisons of the height of a station on the beach, 

 near Man galore^ as had by computing from this co2iStf 

 and by measuring from the low water mark on the 

 other, where there appears an error only of 8^^ ^^^t. 

 This table also contains the terrestrial refractions. 



It will be unnecessaiy to say more here, there be- 

 ing sufficient, by referring to the plan of the triangles, 

 to convey a general idea, and the adjoining detail 

 wilt furnish all the materials for a more critical ex-
