N2 - The second catalog of southern double stars was published by Carl Rümker 1832. We describe this catalog, obtain modern nomenclature and data and estimate the accuracy of his positions for the primary components. We have shown the equinox and epoch to be B1827.0. Of the 28 pairs, 27 could be identified. RMK 23 is RMK 22 and RMK 24 could not be identified. Five pairs observed by Rümker are credited to co-worker Dunlop (DUN) in the WDS. There are two typographical errors. We tentatively identify RMK 28 with COO 261. We have shown the positional data in the 1832 catalog to be accurate and we present a modern/revised version of Rümker's catalog.
