![The events in each of the 28 families were noted on separate investigation sheets, in which the names of every member present at the time of inoculation were entered as either “ inoculated ” or “ not inoculated. The occurrences m each household being entered in each sheet helow the names, it was then easy to compile the following table : ■ __ Inoculated. Not Ward No. House No. Number in- oculated in the family. Number of Attacks. Number of Deaths. Number not inoculated in the family. 1 2 3 4 5 6 1 8 4 1 2 1 63 3 ... ... 1 67 3 ... ... 2 ] 2 24 1 ... ... 3 1 2 • • • • •• 2 15 2 1 • • • 3 99 20 3 1 • • • 4 99 29 3 • •• ... 2 99 39 4 1 1 3 99 42 1 • • • ... 2 99 48 5 ... 3 99 49 1 • •• ... 5 • 99 4 7 1 1 • • • 1 8 2 1 • • • 1 j) 10 4 1 ... 1 99 12 2 • • • • • • 2 *■ 99 13 2 • • • • • • 1 99 18 3 ... 2 99 26 1 • • • • • • 2 r9 30 1 ... 3 99 99 31 34 4 2 1 1 • •• 2 3 99 35 1 1 1 1 » 53 2 • • • • • • 2 )) 80 4 • • • • • • 4 V 84 5 • •• ... 5 99 89 2 • •• • • • 1 99 90 3 • . . ... 3 99 Total .. 71 8 (11-3%) 3 (4-2%) 64 Not Inoculated.

If the inoculated had suffered to the same extent as their uninoculated relatives, they should have had29 deaths from Zstead of 3 only. The proportional number-29-is reduced by 26 which is equal to a diminution of 89-6 per cent, of mortality attributable to mocula- tl0n*The subjoined figures show the number of days which elapsed between the dates of inoculation and the occurrence of a death from plague in these families.
