The mortality of Europeans in West Africa has on several occasions been the subject of discussion in this Institute or of note in the pages of the Journal. In 1886 Dr. T. B. Sprague read a paper on the mortality of Europeans in the Congo, based on the statistics from Stanley's work on the Pounding of the Free State: In 1892 Dr. T. G. Lyon contributed a paper on mortality in various regions of the world from data gathered from Government Reports of the Colonial Office. In 1897 Dr. A. E. Sprague read a paper on the experience of 971 Belgian Government officials on the Congo and 178 employees of a Dutch Trading Company. In the same year Mr. J. E. Hart gave the experience of Colonial Office officials on the Gold Coast and Sierra Leone. Lastly, in 1911, Mr. Hart furnished a copy of the Report on Vital Statistics of European Government officials in the employ of the Colonial Office for the previous year.
