175 pp. Stapled binding, wrappers. A series of lectures on sexual hygiene and related disorders. A revised and enlarged edition of the 1871 original, with a new chapter on syphilis. Hoolihan 2043 (referencing the original printing): "Man's Mission on Earth is a title that was given to several volumes of collected lectures delivered at anatomy museums in Boston, New York and Philadelphia operated by members of the Jordan-Kahn clans and their partners. However, the volumes published under this title by L.J. Jordan, R.J. Jourdain and R.J. Kahn differ in content. At the same time, the content of L.J. Jordan's Man's Mission on Earth is identical to that of Manhood; or Secrets Revealed, authored by LaGrange and Jordan."
