The author develops a system of nasology that classifies nasal types and links nasal form to aspects of character, especially energy and taste. After outlining a methodology of independent, prolonged observation, the text surveys distinctive profiles — including Roman, Greek, cogitative, Jewish, snub, celestial, feminine, and national noses — and discusses their supposed mental and ethnological correlates. It combines lighter sketches with more serious essays, offers practical remarks (notably on acquiring a cogitative aspect), and frames its conclusions as tentative deductions drawn from comparative observation rather than exhaustive proof.
