I have met with three well- marked varieties of divergent squint, of which examples will be given hereafter. The first, or paralytic form of this affection, is better known as paralysis of the third pair of nerves, inasmuch as it is accompanied with paralysis of all the muscles supplied by the motor oculi nerve; consequently there is not merely eversion of the eyeball, but an inability to turn it inwards, upwards, or downwards; there is also a dropping of the upper lid (ptosis) and a dilated and im- moveable pupil. The second form of divergent squint bears a resemblance, so far as the phe- nomena are concerned, to the second variety of convergent strabismus. There is eversion of one eye, but no mutual divergence; the organ can be brought into the centre of the orbit and retained there without causing eversion of the good eye, so long as volition is specially directed to this object, and no longer. Both eyes can also be made mutually to converge. In the third, or most common form of di- vergent squint, there is not simply eversion, but
