Neapolitan duelling code by Luigi De Rosis. Direct bibliographic confirmation supports the 1868 De Angelis edition; Thimm and Gelli also preserve notice of a later second edition, but that later issue remains a bibliographic note here rather than a separately materialized edition pending direct verification. Naples: De Angelis, 1868, 96 pages; retained over Thimm’s 1865 date because a direct edition witness confirms 1868. Individually bibliographically reviewed in phase 89 against the complete source entry and, where needed, independent catalogue evidence.
