![“ the day of the outbreak up to the date of this memorandum [24th October “ 1899] the writer does not admit there is any appreciable error in these statistics. “ In some oi' the villages the number of the residual population at the end of “ the outbreak has been further tested and tallied and found not to throw the “ least suspicion on the records.” The method of calculation adopted by Mr. Anderson is as follows :—“A “ number of protected and a number of unprotected persons live for a day in “ the infected area, and the question is, which class shows the higher rate of “ attack and death from plague. If the number is not the same, as will “ usually be the case, then we must multiply the number of protected by the “ number of days they have lived in the village, and similarly with the unpro- “ tected: thus the product will give the number of daily units of each class : “ these units divided by the number of attacks and deaths from plague among “that class give the daily rate of attack and death as 1, in so many units.” The uuit in fact is 1 (person) X 1 (day). As the result of the labour of the census parties Mr. Anderson was able to compile tables showing day by day the progress of plague in each village, and the events happening in the groups of inoculated and uninoculated respectively. From these he compiled the following summary :— Ihoculatbd. Uninocclated “ Village. Period and its characteristics. Units. Attack. Death. Death-rate 1 in— Unite. Attack Death.
