Karnminnis - 44° 9' 46" 

 Karnbonellis - - 98 1 30 

 Western Light-house 37 48 44; which gives 8134a 

 feet, for the distance between the station Karnbonellis and the 

 Light-house. This distance is said, in the Philosophical Trans- 

 actions for 1797, p. 501, to be 813^8 feet, which differs only 

 6 feet from the above determination ; but it is probable the dis- 

 tance first given is most correct, as the two light-houses appear- 

 ing nearly in the same line at Karnminnis, was the means of 

 preventing us from clearly distinguishing the apex of either, 

 and it was principally on this account that we preferred the ob- 

 servation made at Pertinney. The agreement however proves, 

 hat no inconsistency can be found to obtain with respect to the 

 data before given, for settling the situation of this important 

 headland. 



In the Philosophical Transactions for 1797, page 502, it is 

 mentioned, that the distance from the spot where the late Mr. 

 Bradley made his observations, to the place where his meridian 

 mark was fixed, was 800 feet. But there appears to be some in- 

 consistency in this particular; as Mr. Bradley's own words, ia 

 an extract of a letter now before me, are, it was just 480 feet. 

 Adding to this, 24 feet, the distance between the place of the 

 meridian mark and the line joining the centre of the light- 

 houses, we get the distance of the point O, or the place of the 

 Observatory, (see Phil. Trans. 1797, p. 502,) from the line join- 

 ing the light-houses W, E, = 504 feet ; a space corresponding 

 to 5" of latitude, nearly ; therefore, from the trigonometrical, 

 operations, we get, 



, 49° 51' 44" for the latitude T f M Rradley > s station 

 and 511 4 ,8 for the longitude) 01 Mr * bRADLEY s station.
