[Bull Barrow 
With respect to this last triangle, it must be observed, that 
in the future prosecution of the survey, the side Bull Barrow 
and Blackdown will be obtained by another method, the result 
of which, when combined with that given by this triangle, will 
afford a more accurate means of determining other distances 
which will hereafter depend upon it. This triangle, and like- 
wise the rest of them in this article, are inserted here, as the 
distances deduced from them are supposed to be nearly true ; 
they may possibly be of some service at present ; but at a fu- 
ture period they will be given in a more perfect state.
