The July Bulletin of the Chicago Health Department has some interesting data in regard to influenza. The city has not been free from the disease at any time since the epidemic of 1891, in which year there were 336 deaths reported from this cause. In subsequent years the reported deaths were as follows: 1892, 103; 1893, 88; 1894, 51; 1895, 165; 1896, 17; 1897, 15; 1898, 281, and 304 up to the end of July, 1899. It would appear from these figures that we are entering on another period of special prevalence of the disease, and the figures are more significant when we remember that the deaths directly due to the disorder represent only a small proportion of the total in which its agency has existed. Thus, as the Bulletin shows, while the reported deaths from influenza in the epidemic of 1891 added only 1.25 per cent. to the total
