While browsing through the IMSLP library for vocal scores of nineteenth-century French operas and operettas, I found this file. The original French title is "Le Coeur et la Main."
Although rarely performed nowadays, the operettas of Charles Lecocq were among the most successful French theater pieces in the generation after Offenbach and Gounod -- that is, in the fourth quarter of the century. As such, they form an important link to early twentieth-century French, Viennese, and American operetta. The traffic between stage, film, and reproduced-sound industry/culture is made concrete in the stamp on this cover page: "From Music Department, Edison Laboratory, Orange, N. J." This score eventually ended up in the Sibley Music Library, Eastman School of Music, Rochester, NY. Here is the IMSLP main page link.
