The visual person is often so completely a slave to his sight that when that fails either in itself or through weakness of attention he becomes a wreck off the shore of the ocean of intellect.

When we consider the large proportion just mentioned of pupils of this type, the care which should be exercised by the school authorities in the matter of favourable conditions of light, avoidance of visual fatigue, proper distance-adjustments in all visual application as regards focus, symmetry, size of objects, copies, prints, etc., becomes at once sufficiently evident to the thoughtful teacher, as it should be still earlier to the parent.

There should be a medical examination, by a competent oculist, before the child goes to school, and regular tests afterward.

School examiners and boards should have qualifications for reporting on the hygienic conditions of the school as regards lighting.

The bright glare of a neighbouring wall before a window toward which children with weak eyes face when at their desks may result not only in common defects of vision but also in resulting mental and moral damage; and the results are worse to those who depend mainly on vision for the food, drink, and exercise, so to speak, of their growing minds.
As to the methods of teaching these and also the other sensory pupils, the indications already given must suffice.
