This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: the direction of this movement. Almost every movement along the illusion line in the photographs of all our subjects follows this same relative direction. The movement is in a direction directly opposite to that in which the line seems to be deflected. Furthermore, it should be noted, that the movement does not suffer deflection at each of the obliques, but is a single long sweep. Between 7 and 8 appears a very characteristic fact of movement. Before moving the eye across the figure from the middle line to one of the side lines, the subject makes a corrective movement which brings his fixation to the middle line. This corrective movement is repeated in the later parts of this figure and in the figures from other subjects. In one case under very similar conditions in this figure (193 to 194) the eye does not make a corrective movement before crossing the figure. The corrective movement is, therefore, with great probability to be described as a secondary effort to make the cross estimation more exact through careful fixation. The movement across the figure as seen between 16 and 17 offers nothing worthy of special note. It is not along the direction of the oblique lines. In this respect it differs from some of the crossing movements. The successive movements exhibited between photographs 21 and 30 are very noteworthy because of the close adherence of the movements to the direction of the plain line. After all that had been shown in our photographs with regard to the irregular fixation of points, it constituted a mild shock 'to find the eye following a straight line with such fidelity. There can be no possibility of error in regard to this result for it occurs again and again under the greatest variety of conditions and with all more
