derived from two double azimuths of the star, supported by 
several computed azimuths, applied to single but accurate 
observations. 
The angle between Butser Hill and the staff at Brading Down, 
was o° 15' 35", 5. This, with the above angle, 21 0 14/ 11", 5, and 
particular angles of the series, gives, 
The Bearings of certain Sides from the Parallels to the Meridian 
of Dunnose. 
Dunnose and Butser Hill - 20° 58' 39" NE 
Butser Hill and Highclere - 34 20 17 NW 
Highclere and Nuffield - - 35 3° 4° NE
