1996-11-21 A duplicate case entry for South Korea, Year 1876 (case 7301876), has been deleted and two new cases, Year 1858 for the Orange Free State (case 5641858) and Year 1922 for Egypt (case 6511922), have been added to this collection. Thus, the total number of cases has changed from 13,907 to 13,908 observations. In addition, the data have been reformatted from tab-delimited to space-delimited format.
