fill, as the juice is prevented exuding properly. Dr. D. 

 Cunningham, of the Bengal Medical Service, in 1875, 

 published microscopical notes regarding the fungi present

Poppy seeds in the granary and store pots are injured 

 by several insects : Bruchus, two species, in their larval 

 and perfect form ; Calandra, sp., the perfect insect only ; 

 dipterous larvae ; Sitona, sp., larva and perfect forms ; 

 Tetranychus papa verse, poppy seed mite ; Tipula, sp. t the 

 larvse and pupae. The insects which attack the young
