DEVELOPMENT of a certain 



the next term, fin i6<p ,y , being multiplied by <? ,r , a very fmall 

 fra&ion, is on that account to be negleded, as well as all the 

 terms which follow it, for fimilar reafons. 

 To determine & t we have <p' ~ 66 . 22'. 54*. 



<p"—66°. 29'. 18*. 75 

 <p'"=66°. 29'. i8".75 

 &c. 

 Hence it appears that n 66°. 29. 18^.75 — i- 1 604440.
