we get 334,04,5 feet for the distance between the same stations : 
hence the mean, 33406,8 feet, may be taken for the true distance 
between Boughton Malherb and Westwell Down. From this latter 
triangle also, we obtain the distance from Boughton Malherb to 
Tenterden 530 97,6 feet.

By the two last triangles, we get 52472,4 and 52481,4 feet for the 
distances of Tenterden from Silver Hill ; the mean of which, 52476,9, 
we shall hereafter use in determining the distances of the objects, 
intersected from those stations. 
The distance of Goudhurst from Tenterden, and that of Tenterden 
from Fairlight Down, are derived from those given by General Roy, 
in the Philosophical Transactions, Vol. LXXX. augmented in the pro- 
portion of 141747 to 141753. The distances also, hereafter made use 
of, between Lydd, and the stations on Fairlight Down, Tenterden 
Steeple, Allin on Knoll, and High Nook, together with that of High 
Nook from Allin^ton Knoll, are obtained by increasing the distances, 
found in the same work, in the above proportion. It is proper to
