Venus on the face of the Sun; andlines were draWn be- 

 tween the limhs, in the dired:ioa of their centers, of fuch 

 a determined length, as the micrometer has given them. 

 Many of the meafures were taken from the fartheft limb 

 of the Sun, as well as from the nearefl, to both limbs of 

 Venus, and thefe meafures were afterwards reduced to the 

 neareft diftance of the neareft limbs, as they are exhibited 

 in the preceding table, ufmg the diameters of the Sun and 

 Venus, as they are ftated above. 



As a confirmation of the foregoing conclufions, I have 

 fubjoined the obfervations of aftronomers, in different 

 places, of the contads and durations of the tranfit of 1761, 

 as they have fent them to the Royal Society, together with 

 the longitudes and latitudes of the places of obfervatlooj 

 on which the following calculations depend.
