PLAGUE OX FIGS AXI) RAISINS. 
Rilisins and lio's were contaminated with cultures of plague, and lh(‘ 
attempts made from time to time failed to recover the oro-anism by 
means of cultures and inoculations. This work was undertaken in 
order to determine whether such articles from infected localities could 
transmit the infection. The difficulties of determinino- this (piestion 
were increa.sed by the fact that it is not practicable to sterilize the tio-s 
and raisins. It was also found that both the.se articles contain 58 p(*r 
cent of o-luco.se, and that the plaoue bacillus will not o-j-ow in a 58 ])er 
cent glucose medium. 
The plague organism was never recovered from raisins and figs, 
even on the dav following the inoculation, and it mav be (hdiniti'lv 
stated that there is little danger of these articles carrving the infection.
