The King's Order of Natural Science

The King's Order of Natural Science was a Providence-based corporation formed in 1920 by Orville L. Leach and others, with the stated purpose of "preservation of individual right to select such methods of curing and preventing disease as the person thinks proper, the prevention of vivisection or any cruelty to animals and the overthrow of compulsory vaccination or inoculation of germs or serums" (i.e. anti-vivisectionist and anti-vaccinationist).
