operations.

the refuifs were 2042 l feet. As the view from its extremities 
2042J 
was very confined, another bafe of 1861 yards was deduced 
from it, fituated on the high lands that edge the Severn, hav- 
ing a very extenfive and beautiful profpeft. F rorn the extre- 
mities of this fecond bale, all the angles were taken with a 
tolerably good theodolite on which two minutes might be 
eafily read off. The refults here given are the diftances from 
the various places to the weftern extremity of their bafe, their 
perpendicular diftances to its meridian, and its diftance from . 
thefe perpendiculars*:
