This is attributable to the important generalisation of the aetiology of strabismus made by Bonders, that in by far the greater number of cases it is due to hypermetropia. The time at my disposal will not permit me to enter into any details in regard to the mode in which hypermetropia, or long-sightedness, leads to strabismus, but it will be enough to say that the hypermetropic eye is a flattened eye, that in accom- modation for near objects great convergence of the eyes is required, and that a powerful and sustained nervous impulse is required in order that a near object should be fixed by both eyes, and that, owing to defective association between the effort for ac- commodation and that for convergence, convergent squint is frequently induced. Other striated muscles that have been noticed as being occasionally affected in a reflex manner by disease of the teeth have been the levator pal- pebrae and the orbicularis palpebrarum ; the former supplied by the third nerve, the latter by the seventh; the paralysis or paresis of the former
