Casimir Stanislas d'Arpentigny (reference article)

Wikipedia's article on Casimir Stanislas d'Arpentigny, the nineteenth century French officer credited with founding modern chirognomy, the study of hand shape in palmistry, is a community edited reference page rather than a peer reviewed publication. It is reliable for standard biographical facts such as his military career and his authorship of the foundational chirognomy text, and less reliable for evaluating chirognomy's own claims. Use it for basic biography; a claim about the validity of hand shape reading needs an independent source, since palmistry itself carries no scientific verification.
