Includes the description of “Ricord’s chancre”, the initial lesion in syphilis. Ricord re-demonstrated the specific character of syphilis and divided it into the three stages, primary, secondary, and tertiary. 

Repeating John Hunter’s experiment, Ricord proved that syphilis and gonorrhoea were separate diseases. After Hunter, he was the greatest authority on venereal disease. 

The first of several English translations appeared in 1842.

Ricord's extensive work with veneral diseases at the Hopital du Midi includes 66 hand-colored ithographs illustrating a multitude of conditions at various levels of infection in both sexes. The illustrations were drawn from nature by Bion and Beau and are accompanied by case histories and treatment modes. Digital facsimile of the 1862 edition from BnF.gallica at this link.
