Indian turning white. A Winnebago Indian, Louis Armell, living on the reservation, is said to be the object of scientific observation because for many years his skin has gradually been turning white. He is now 54 years old. He still has “copper patches” but physicians believe that if he lives a few more years he will become entirely white.
