Source for Palmer's death by typhoid fever in October 1913 following an August 1913 incident; his account of the September 1895 discovery; his development of the Innate Intelligence concept as a segment of that Intelligence which fills the universe; his description of chiropractic as systematized knowledge for the prolonging of life; his tone-based theory that the cause of disease is any variation of tone, nerves too tense or too slack; and his 1906 jailhouse remark that he was not in a cell for lack of principal, but for an abundance of principle, given after he chose incarceration over paying a fine for practicing medicine without a license.
