Though Sportscaster Bill Slater now ingratiatingly explains what is happening on the screen (apparently for the benefit of the blind), the film itself remains a brilliant solo on the optic nerve. Some memorable passages...
...Street & Smith, Nick Carter (in real life, Colonel Frederick Van Rensselaer Dey) pounded out a novel (30,000 words) a week. Burt L. Standish (William Gilbert Patten) manufactured 30,000 words a month about Frank Merriwell. Other S. & S. standards: Oliver Optic (William T. Adams), Horatio Alger...
Duration, Not Intensity. Professor Bissonnette concludes that all this proves that the pituitary gland, which lies at the base of the brain, is affected by light transmitted by the optic nerve. He points out that if an animal's optic stalk (connecting the eye and the brain) is cut, the animal will change its breeding season. He also found that the intensity of light seems to make little difference; what counts is its duration. The pituitary gland apparently is also stimulated by color: red light, for example, moves starlings to mate more than any other...
Cones & Rods. The retina (the screen upon which the lens of the eye casts the image) has two kinds of visual cells: cones, each with its direct line to the brain; rods connected in multiple to the optic nerve fibers. The cones give sharp, color vision, work in bright light only. The rods "gang up" faint and dim impressions in weak light, catch no color. Some animals have cones but apparently no color vision; no known color-seeing animals have rod cells alone...
