In the above triangle, I have computed the distances of Wendover and Bow Brickhill from 

 Quainton with 92400,7 feet, the side Wendover and Bow Brickhill, as determined in a 

 former triangle.'

Therefore, 67490 may be considered as nearly the true distance, in feet, between Quainton 

 and Bow Brickhill.

As the stations Lidlington, Trusler Hill, together with Crouch Hill, Cumner Hill, and 

 Whiteham Hill, have been used for purposes of greater importance than secondary ones have 

 been generally applied to, I shall insert the triangles formed by their intersections in this 

 article.
