of elevation, fixation was eccentric, and there were nystagmoid movements in this eye. There was slight ptosis, the left interpalpebral fissure being 9 mm. at its highest point and the right 10 mm. The action of the levator palpebrae superioris was good. There was marked secondary contracture of the inferior rectus muscle. Operative intervention was carried out in two stages with a five-week interval between them. (1) Recession of the inferior rectus 7 mm., which was found to be in tight contracture. Recession of the external rectus to the equator, and resection of 5 mm. of the internal rectus. Fig. 2 shows the result after this operation; the patient is looking up. (2) Resection of 7 mm. of the paralysed superior rectus and transplantation of the
