fixation-point

At once a visual and an emotional fixation-point, the glittering glass (a light-reflecting surface) fixes the narrator's eye and his sick state of mind: "From this time/I found my sickly heart had tied itself/Even to this speck of glass" (again the word tied — "tied to dead things" — comes up in relation to the inanimate).

Invariably, the papers, being at a distance from the fixation-point, and being seen by indirect vision, are arranged, not in

In the experiments here described it was always found possible so to reduce the light that the distinct, entire image of the dumb-bell (2, Fig. 7) never appeared localized on the final fixation-point, although in the control, _H_, of Fig. 7: 1, was always distinctly visible.

With these two precautions taken, the image on the final fixation-point is like either 3, 4, or 5.

It was impossible for this second after-image streak to originate in the point _b_, because it appeared equally when _b_ was only an imaginary fixation-point ....

But the image 2 or 3 may indeed be localized quite over the final fixation-point.

The image is localized either at _A_ (Fig. 5), or at the final fixation-point (_P_ or _P'_, according to the direction of the movement).

If, however, the streak has not faded by the time the eye has come to rest on a new fixation point (by supposition to the right of the old), we should expect the streak to be localized to the left of this, that is, to the right of the former fixation-point.

Therefore we must probably picture to ourselves that the sensation from the strip of the retina stimulated during the quick eye-movement is, _during the interval of movement or at least during the greater part of it, localized as if the axis of vision were still directed toward the original fixation-point.

The image flashes out over the final fixation-point, green and straw-yellow, just as the end-circles of the dumb-bell appeared without their handle.
