47' 42".98, the difference of longitude ; to wliich adcl 

 the difference of longitude between Yerracondah and 

 Savendroog, equal 59' 14". 8 3, we have 1° 46" J 7'. 8 1 

 for the longitude of Kylasghur, east from the meri- 

 dian of Savmdroog. 



12. Latitude and Longitude of Karnatighur, and 

 the position of its meridian, deduced from that of 

 Kylasghur. 



The southing of Karnatighur from Kylasghur is 

 95144 feet, equal to an arc of 15' 43".()1 on the meri- 

 dian o^ Kylasghur ; and the easting is 1093.83 feet, 

 equal to 10".8 of a great circle at right angles to the 

 said meridian, and passing through Karnatighur. 

 From the nearness of the meridians of these two 

 stations, the former arc may he considered as the 

 difference of latitude, and therefore being subtracted 

 from the latitude of Kylasghur, we have 12o 34' 

 ^7"-Q9 for the latitude of Karnatighur. Hence, by 

 using the co-latitude 77° ^5' S22".31, and the small 

 perpendicular arc 10 '.8, we shall have the difference 

 of longitude 1 1'.OG, and the convergency of the me- 

 ridian of Karnatighur towards that of Kylasghur 

 2".46 nearly. The former of which being applied to 

 the longitude oi Kylasghur, will give 1° 47' 8". 87 for 

 the longitude of Karnatighur from the meridian of 

 Savendroog, E. 



Now the observed angle at Kylasghur, between 

 the north pole and Karnatighur, was 179° 20' 28".83, 

 whose supplement is 0° 39' 3r'.17, which will there- 

 fore be the angle at Karnatighur, between the north 

 pole and the parallel to the meridian of Kylasghur ; 

 from which subtract the convergency, we get 0° 39' 

 28".71 for the angle between the north pole and 

 Kylasghur, westerly ; and this subtracted from 93* 

 28' 42".22, the angle formerly taken at Karnatighury 

 between Kylasghur and Carangooly, gi\'es 92° 49- 1 3'.5 1 

 for the angle between the north pole and Carangooly,
