The mean of thefe 12 central durations gives the 
mean central duration — 5 h 58' 5" ; from this cen- 
tral duration, we fhall find that the geocentric leaft 
diftance of the centers is — 57 1 ", or 9 ' 31". Let 
us compare the above apparent leaft diftance of the 
centers meafured at Rodrigues with this geocentric 
leaft diftance of the centers, and we fhall find that 
the parallax of the Sun from thence refulting is = 
8 ", 56 the fame as before. Thefe refults of the pa- 
rallax, arifing from the companions of the apparent 
leaft diftances of the centers, agreeing with the for- 
mer determinations of the parallax by the internal 
contacts, are a proof of the accuracy of this mea- 
furement of the created: diftance of the limbs made
