On the left side no traceof the muscle could be detected. As regards the muscles attached to the eyeballs theywere all, with the exception of the two internal recti,inserted into the sclerotic in abnormal positions. Thesuperior, inferior, and external recti were inserted too far Pulley of super,oblique. Super, rectus. Super, Normal insertion ofsuper, oblique.

The superior oblique muscle in each eye, insteadof its usual position to the outer side of and posterior tothe insertion of the superior rectus, was inserted to theinner (nasal) side of the superior rectus, and reached ashort distance anterior to it. The inferior oblique muscleswere nearly normal in their insertion. In addition to this displacement there was considerablealteration in the length of most of the muscles. Nearlyall were too short, the difference being as much as 10 and11 mm. in the case of the inferior recti. The superiorrecti were very thin and almost membranous, but theother muscles appeared well developed and of aboutnormal size. The orbital nerves appeared in all respects normal. 270 CONGENITAL DEFECTS. Briefly, the following deviations from normal were pre-sent : (1) A backward insertion of the superior, external, andinferior recti. (2) A forward
