with the observed angle at Carraton Hill = 16 0 22' 1", we get 49435 
feet for the distance of the Eddystone Light-house from the build- 
ing on Rame-head. It may be proper to observe, that the Eddystone 
Light-house is nearer to the Rame-head than to any other point on 
the coast.

From the two last triangles we obtain 79640 feet for the mean 
distance between the Lizard Signal-staff and the station on Karn- 
bonellis. Computing with this distance, and also that from the 
Western Light-house to the same station, with the observed angle 
o° 31' 8", we get 1857 feet for the distance between those objects.
