I am sorry I did not get better notes on some of the above cases 
and also that notes taken by Dr. Fung, my assistant, in Chinese, 
was lost. 1 made cultures from bubos of four cases. Three of which 
showed characteristic bacilli pestis. One of these cases recovered. 
During the épidémie season of ign 1 treated, in ail, about ihirty 
cases with sérum. None of the cases which had their initial symp- 
toms 24 hours before the sérum was given recovered. 
When counting up with my assistant, Dr. Fung, soon after the 
épidémie was over we counted 12^who had recovered. We vere al- 
ways careful in looking for any other source of infection which 
might cause the bubo and while I must confess we do not hâve 
the three postulâtes of Koch to prove that any of these cases were 
Plague, still I believe they ail were and I believe if given within 
ten or twelve hours after the initial symptoms the Anti-Pestis 
Sérum has virtue. 
It is possible the cases which recovered were less virulent, but 
it will be noted that ail cases which had their initial symotoms 
24 hours before sérum was given, died. In previous épidémies 
with other treatment, I can not remember more than one or two, 
where was a positive diagnosis made, which recovered. 
As a rule I found it easier to insert the needle into one of the 
veins in the back of the hand. The subeutaneous injections were 
usualy given below and around the bubo.
