The number of vibrations made by the pendulum in 24 
mean solar hours, as obtained by the disappearance of the 
white disk, from rates deduced by the transits of stars, is 
86223,744, and by the sun 86223,645. And of those result- 
ing from the mean of disappearance and re-appearance by 
the stars, is 86223,877, and by the sun 86223,786 ; but the 
sums of the factors being respectively 127,5, and 148, the
