...know was that the man he had just intimidated was not a Negro but a white. He was John Howard Griffin, 39, Dallas-born author (The Devil Rides Outside) on assignment for Sepia magazine, a Negro monthly (circ. 61,975) published in Fort Worth. His skin darkened by pills,* ultraviolet treatment and vegetable dye, his straight brown hair shaved to the poll, he was touring the Deep South to see how it felt to wear the black man's skin. In the current issue of Sepia, in the first of five installments. Griffin began telling what it was like...
...Griffin took Oxsoralen, a drug sometimes administered to victims of vitiligo, a disease that produces milk-white patches on the skin. The drug makes the skin extraordinarily sensitive to ultraviolet rays; under sunlamp or sunlight exposure, the skin turns a deep brown. * From Hughes's poem "Dream Variations...
...made surgically pure by being pumped through a 7-ft. cube housing 72 small cylinders, each containing an ultraviolet arc. The cylinders were designed so that every passing air particle swirled within 3 in. of a germ-killing arc light. Since ultraviolet rays kill germs more effectively at close range-their germicidal effect is proportionate to the square root of the distance-a microbe had only 1/256th as much chance of surviving a trip through the cylinders as it would have under an ultraviolet lamp hanging 4 ft. above the operating table...
...thin, high, outer fringe of the atmosphere, the Fort Monmouth men explained, the atoms of gas are ionized by solar ultraviolet light into positively charged nuclei and negative electrons. Theory suggested that at a certain altitude above the earth this charged plasma should have a sort of elasticity that would permit hydromagnetic waves to pass along it, rather like mechanical waves traveling along a coil spring. The Fort Monmouth scientists found that the Argus explosions started just such waves in a layer of plasma about 1,500 miles high. The waves were about 1,000 miles long, and they traveled...
...Inside the operating room, before and between operations, the floor must be swilled with this solution, the excess being removed by a wet-pickup vacuum cleaner. Ultraviolet lamp tubes girdle the operating room, high enough to offer no risk of skin burns...
