The object would, of course, also have to be an unknown one, as, otherwise, the converse of the above comes into play, and the distance could be estimated by the angle which the known diameter of the object subtends at the eye; but this necessitates the size of the object being known beforehand and the employment of perspective.
Then, plunging into the Gulf of Mexico, it subtends the arc formed by the coast of Alabama, Mississippi, and Louisiana; then skirting Texas, off which it cuts an angle, it continues its course over Mexico, crosses the Sonora, Old California, and loses itself in the Pacific Ocean.
Above all, let us strive to disengage ourselves from homogeneous space, this substratum of fixity, this arbitrary scheme of measurement and division, which, to our greater advantage, subtends the natural, qualitative, and undivided extension of images. There is no disputing the absolute value of this pure perception.
To-day's dinner subtends a larger visual angle than yesterday's revolution. A mote in my eye is bigger to me than the biggest of Dr. Gould's private planets. Every traveller is a self-taught entomologist.
I assert further, that the earth is that particular kind of a globe which is termed an oblate spheroid; because it is found by measurement in the direction of the meridian, that the length on the surface of the earth which subtends a given angle at its centre, diminishes as we recede from the equator and approach the poles.

But I maintain, that I, the Professor, am a good listener. If a man can tell me a fact which subtends an appreciable angle in the horizon of thought, I am as receptive as the contribution-box in a congregation of colored brethren.
