prised on opening this ten days later to find two of them alive 

 and kicking. They were for a second time "'gassed" for 24 hours, 

 and then put back with their dead companions. Some two or 

 three weeks later I found one of them was still in "status ante 

 bellum," so I gave him a week's cyanide treatment, and he never 

 "came to" thereafter. The bottle was in almost daily use until 

 April 1, and killed quickly all other insects placed in it up to that 

 date.
