FOOTNOTES:
[1] Physiological anatomy would probably explain this fact by suggesting that a sort of punctum cæcum is displaced in order to conceal the object that one does not wish to see.
[2] Every one knows that the farther an object is, the smaller it appears. An object which is seen under an angle of one second, is at a distance of 206,265 times its own diameter, whatever it may be; because as there are 1,296,000 seconds in the circumference, the ratio between the circumference and its diameter being 314,159 × 2, it follows that this object is at a distance equal to 206,265 times its own diameter. As Capella sees the semi-diameter of the terrestrial orbit only under an angle 22 times smaller, its distance is 22 times greater. Capella is therefore at a distance of 4,484,000 times the radius of the terrestrial orbit. Future micrometrical measurements may modify these results concerning the parallax of this star, but they cannot change the principle upon which the conception of this work is grounded.
