24, Observations on the eclipse of the sun, June 16, 1806 
Astronomy, supposing the error of the lunar tables to be in longitude 
— 25" 5, and in latitude —6"-8,* E found the mean time of the least appa- 
rent aeaice of the centres of thesun and moon at Pawlet wasat 11h,14’ 4” 
The > °s parallax —©’s parallax, m longitude was then +7’ 53”-86, in lat- 
itude —21'A""72; the moon’s apparent semidiameter 16’ 41:18; the 
sun’s semidiameter 15’ cae 5, being the same during the whole of the 
eclipse. Inestimating idiameters I supenerd the rea tode-

might arise in the calculated time of the ecliptic conjunction will be, 
nearly obviated, by taking the mean of the times deduced. from. the 
beginning and end of the eclipse, or from the beginning and end. of 
the total darkness. From the preceding data I found that the least 
distance of the centres of the sun and moon according to the tables 
thus corrected was 58-28, and the difference of their -semidiameters 
58°68. — The difference of these numbers 0” “4, is nearly the addition.
