66        Accommodation: Study of Images
difference which one would naturally expect from the fact that when the front of the sclera becomes more convex the sides must become flatter.
When an effort was made to see at a distance the image reflected from the side of the sclera was larger than the image obtained when the eye was at rest, indi cating that this part of the sclera had become less con vex or flatter, because of elongation of the eyeball. The image obtained during normal accommodation was also larger than when the eye was at rest, indicating again a flattening of the side of the sclera. The image ob tained, however, when an effort was made to see near was much smaller than any of the other images, indi cating that the sclera had become more convex at the side, a condition which one would expect when the eye ball was shortened, as in hypermetropia.
The most pronounced of the changes were noted in the images reflected from the front of the sclera. Those on the side of the sclera were less marked, and, owing to the difficulty of photographing a white image on a white background, could not always be readily seen on the pho tographs. They were always plainly apparent, however, to the observer, and still more so to the subject, who regarded them in a concave mirror. The alterations in the size of the corneal image were so slight that they did not show at all in the photographs, except when the image was large, a fact which explains why the ophthal mometer, with its small image, has been thought to show that the cornea did not change during accommodation. They were always apparent, however, to the subject and observer.
The corneal image was one of the easiest of the series to produce and the experiment is one which almost any-
