The sun rose without a cloud, and the sky continued equally clear throughout the day.

The transit at Cook's station lasted from about half-past nine in the morning until about half-past three in the afternoon, and all the observations were made in a satisfactory manner.
But, on the discussion of the observations made at the different stations, it was found that there was not the accordance that could have been desired--the result varying from eighty-eight to one hundred and nine million.

The celebrated mathematician, Encke, therefore reviewed them in 1822-'24, and came to the conclusion that the sun's horizontal parallax, that is, the angle under which the semi-diameter of the earth is seen from the sun, is 8 576/1000 seconds; this gave as the distance 95,274,000 miles.

Subsequently the observations were reconsidered by Hansen, who gave as their result 91,659,000 miles.

Still later, Leverrier made it 91,759,000.
