Traité pratique des maladies vénériennes.

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.
