London during the present epidemic. These figures deal only with the cases that 
were completed in 1901 ; I regret that I have not seen later figures than these. 
The doubtful cases, 63, of whom 41 died, have been excluded.

On November 30 last the Times gave similar particulars for 330 cases 
completed up to that date, which are shown in

investigate again when later figures are available.
