Which triangle gives 37431 feet, for the distance between Stan- 

 more and Hanger Hill Tower. 



The angle at the station on Bow Brickhill, (see the preceding 

 article,) between Wendover and Kinsworth, is 46 18' 8",5; 

 and the distances from it to these stations are 924.02,2 feet, 

 and ^7668 feet respectively : these give the following triangle. 

 Bow Brickhill - 46 18' 8", 5 

 Wendover - - 38 25 21,25 

 Kinsworth - - 95 16 30,25 

 From which the distance between Wendover and Kinsworth 

 is found =± 67090,7 feet. The observed angle at Wendover, 

 between Bow Brickhill and Stanmore, is 102 22 v 29"; from 

 which, subtracting 38 25' 2i // ,25, the angle between Bow Brick- 

 hill and Kinsworth, we get 63 57' 7",75, for the angle between 

 Kinsworth and Stanmore. Again, the observed angle at Kins- 

 worth, between Bow Brickhill and Stanmore, is 173 37' 44"; 

 from which, subtracting the angle between Bow Brickhill and 

 Wendover, we get 78 21' 13",75, for the angle between Stan- 

 more and Wendover. If these computed angles are actually 

 such as might be observed, were Kinsworth and Wendover 

 visible from each other, the angle at Stanmore between those 

 stations ought to be 37 41' 39", nearly : but the observed angle 

 was 37 41' 4i",75; which is so nearly the computed one, as to 

 leave little doubt of the accuracy of those data from which the 

 angles are derived. The distance from Wendover to Kinsworth 

 is 67090,7 feet.
