The results from hundreds of persons of all manner of occupations, ages, and of both sexes, agree in saying that the point lies too far toward the larger square.

In reality it is in the exact middle.

This is just the opposite of the result of the experiments in the laboratory, where the conditions were the reverse, i.e., to find the middle as it appears to the eye.

Here, therefore, we have a complete confirmation of the illusion; and it is now fully established that in all cases in which the conditions of this experiment are realized we make a constant mistake in estimating distances by the eye.[6] [Footnote 6: In redrawing the figure on a larger sheet (which is recommended), the connecting line may be omitted, only the mid-point being marked.

Some get a better effect with two circles, the intervening distance being divided midway by a dot, as in Plate II.] For instance, if a town committee wish to erect a statue to their local hero in the public square, and if on two opposite sides of the square there are buildings of very different heights, the statue should not be put in the exact middle of the square, if it is to give the best effect from a distance.
