David Quinn 
Petition and memorial of David Quinn, asking for the re-establishment of Negro slavery in the United States [EPUB ebook] 

Slavery was abolished in certain states, and David Quinn sent a petition and memorial to the government asking for its reinstatement in those states as well as its reinstatement in all other states and territories. In addition to asserting that there is a general disparity among human races, which breeds chaos and hostility, the paper makes the case that human rules must be in accordance with the laws of nature. According to Quinn, once the mind gives way to matter, mentalities become as varied as the hues of human skin, and although education may advance, it will always be constrained by the unique or universal limitations set up by nature. According to the text, there are seven different types of men: Caucasian, Mongolian, Malay, Australian, Indian, Arctic, and Negro. These distinctions are as clear-cut as those between various animal species.
