The parallax of the moon has to be taken into consideration in the case of the solar eclipse. Our works regard the maximum value of parallax as equal to 1/15 of the planet's motion; which means that the maximum mean parallax of the moon is 52' 42" and that of the sun is 3'56" ; compared with the findings of modern astronomy there is only a slight error in the value of the moon's parallax; but that of the sun is very much mistaken. Modern discoveries show that the maximum value of the equatorial horizontal parallax is 57' 1" for the moon and 8.6" for the sun.
