THE IMPORTANT factor in the production of convergent comitant squint is the primary force which turns the eyes in, i. e., the excessive convergence innervation. Little is known about this in the majority of cases of squint. In only one group is one thoroughly cognizant of the manner in which an abnormal convergence stimulus is produced and how it causes squint. This is the group in which the convergence is due to excessive hypermetropia in early childhood. There is good reason to believe, as has been pointed out in previous papers,1 that all the other forms of squint except those which are paralytic in origin are due to a similar increase in convergence tone, however ignorant one may be as to the manner or cause of its origin.
It is the purpose of this paper to consider the sensory relationships found in all types of convergent squint and to
