the  heights  too  final].  For  it  would  then  appear,  that  it 
is  owing  to  accident  alone  that  the  exceptions  of  this  kind, 
happen  to  be  at  that  preoife  time  of  day  ; that  they  are 
deviations  which  are  ftill  to  be  expected, till  more  circum- 
ltances-  have  been  taken  notice  of  in  the  obfervations,  and 
new  equations  are  introduced  in  the  formula;  and  that 
having  admitted  the  exceptions  on  the  contrary  lide,  I. 
ought  to  have  left  thofe  in  the  bulk  of  iny  obfervations, 
before  I deduced  the  mean  laws  from  them,  which  would 
have  brought  me  nigher  to  the  conclufions  drawn  from  Sir 
george  shuckburgh’s  and  Colonel  roy’s  obfervations,. 
The  late  Mr.  de  la  condamine,  one  of  thofe  rare

jufqu’a  ce  qu’on  ait  embraife  plus  de  circonftances  dans  les  obfervations,  et  de 
nouvelies  equations  dans  laformule;  et  qu’ayant  admis  les  exceptions  contraLres, 
je  devois  laifler  celles  la  dans  Tenfemble  de  mes  obfervations,  avant  d’en  deduire 
les  loix  moyennes:  ce  qui  m’auroit  rapproche  d’avantage  desrefultats  des  obfer-

Feu  Mr  de  la  condamine.  Fun  de  ces  hommes  rares  qui  favent  s’interefler
