APPENDIX. 



EXAMPLE. 



July the fecond, the apparent altitude 

 of Snow Peak was obferved to be, at the 

 diftance of 37507 yards or 18' 30", 

 The height of the eye being 5 I- yards, 



the complement of the dip is - - 89 56 11 



♦ — — — 



Hence the angle BAE92 8 31 



Horizontal diftance 18 30 



2* 12' 20" 



92 27 



Subtra£led from 180 



Angle B 87 32 59 

 Semidiameter of the earth 6966382 

 Height of the eye 5 f 



Semidiameter + height of the eye 6966387s 



As fine B 87° 32' 59''' Co. Ar. 0,0003972 

 TofineBAE92 8 31 9,9996965 



So is femidiameter + height 



of the eye = 6966387 | yards 6,8430076 



To 6967888 /6,843ioi3 



Semidiameter 6966382 



Height 15C6 in yards.
