This value of ?• is unexpectedly small, but it is confirmed by the facts observed in 
Sheffield in 1887-8 and London in 1892-3; these are given in Table XVI., from 
which doubtful cases, where the records with respect to the nature of the vaccina- 
tion were incomplete, are excluded. (See Report of the Commission, pp. 71 — 74.)
