Only five hours after the transit of Venus on June 4, 1769, there was a total solar eclipse.

Title: Observation of a Solar Eclipse the 4th of June, 1769, at the Observatory at Austhorpe, Near Leeds, in the County of York. by J. Smeaton, F. R. S.

N. B. The beginning and end of the eclipse were observed by an excellent 3½ feet treble object-glass telescope, constructed by Dollond, with the smallest magnifier, which enlarged the diameter somewhat above 80 times. As there is no defect in quantity of light from the Sun, the object glass was contracted by an aperture to 2½ inches, and the object was perfectly sharp and distinct.

The quantity was taken by a parallel wire micro- meter, upon an equate-real apparatus, which rendered it very commodious for the purpose ; by which the part of the Sun's diameter, remaining uneclipsed measured at right angles to a line joining the horns, was 889 such parts as the Sun's diameter, taken the same day at 1½ in the afternoon, measured between two parallels of declination, 2041.
