Difference of latitude, ?ie«r/j/. 134 56,43 



The latitude of a point where a great circle pass- 

 ing through Paiidree station, and cutting the me- 

 ridian of Trivandeporum at right angles, will be 

 13° 10' 49'',02 — , from which deduct the latitude 

 of the station at Trivandeporum, equal 1 1 ° 49' 52",59, 

 will leave 1° 34' 56',43, or \\5m3^ nearly; by 

 which divide the number of fathoms in the terres- 

 trial arc = 95721,3266, &c. we shall have V = 

 60494 fathoms, nearly, for the degree in the mid- 

 dle of tlie arc, or latitude 12° 32' nearly. 



APPENDIX. 



Since the account of the meridional arc was made 

 out, I liave completed the measurement of a de- 

 gree perpendicular to the meridian in latitude 12° 

 32' nearly, which is derived from a distance of 

 fifty-five miles and upwards, between Carangooly 

 and Curnatighur ; two stations nearly east and
