Summary
Experiments are described which show that, glass surfaces treated with DDT exhibiting feeble activity againstCiliex fatigans Wied can be reactivated as a result of their storage in a box made of Burma teak. The reactivation appears to be specifie for Burma teak, and results obtained with other timbers are described. Some experiments have been carried to elucidate the mechanism of reactivation. Further work is in progress.
