DEVELOPMENT of a certain 



the next term, fin idip'-", being multiplied by e'", a very Imall 

 fradlion, is on that account to be negledled, as well as all the 

 terms which follow it, for fimilar reafons. 

 To determine 6, we have (p' r: 66 . 22'. 54*. 



<^'=Lb6°. 29'. 18'''. 75 

 ?)"'=66°. 29. i8*'.75 

 &c. 

 Hence It appears that 6 — 66°. 29'. 18'''. 75 =: 1.1604440-
