Case 2. The patient, a boy, 9% years of age, attended our clinic on December 10, 1951. He had impairment of vision and difficulty in seeing at night for the past three or four years. Like his brother he had also been given injections of placenta extract in 1951, totaling 100 cc. His vision remained unchanged.

Physical examination. Height 100 cm. Weight 20 kg. He was short in stature and fat. His heart and lungs were both normal. His extremities showed no abnormalities except flat toes. His hair was curly. His genitalia was underdeveloped but both testicles were present (Fig. 1). His mentality was also low, but he was comparatively more intelligent than his brother.

Eye examination. Some of his eyebrows reached 3.5 cm in length and some eyelashes were 3 cm long (Figs. 6 and 7). When he fixed with both eyes, there was deviation to the right side. The eyes showed no external abnormalities. The retina near the equatorial region of both eyes was sparsely studded with pigment patches like bone corpuscles. A short distance from the nasal side of both discs there were symmetrical crescent-like whitish patches concentric with the margin of the discs. The discs and the retinal yessels showed no demonstrable changes. The foveal
