The Sun's parallax is alfo found, by comparing the to- 

 tal duration between the internal conta£ts, as it was ob- 

 ferved in different places, with the duration at the center 

 of the earth, viz. ^^. 58'. i''.

The mean of all the preceding determinations of the 

 Sun's parallax is 8^52 on the day of the tranfit, in June, 

 1 76 1, which gives 8 ''65 for his horizontal parallax at his 

 mean diftance from the earth. 



Mr, Stuart of Edinburgh, whom I mentioned before, 

 deduces the parallax and diftances of the bodies that com- 

 pofe the folar fyflem, from, the Newtonian theory of gra- 

 vitation, and the periodical times of the Sun and Moon. 

 As he proceeds upon the fuppofition that the diftance of 

 the Sun from the earth is very great, it would therefore 

 feem, that the conclufion fliould be accurate, in propor- 

 tion to the greatnefs of that diftance. His method de- 

 pends
