Forty wasps were used in each exposure. not. When decompressed at the time they first ceased moving (, 10-30 minutes in oxygen and carbon dioxide, 40-60 minutes in oxygen), none of the former exhibited permanent injury; whereas, all but about 10% of the latter remained inactive (Table II). Flies in oxygen and carbon dioxide were also subjected to the same length exposures that caused flies in oxygen without carbon dioxide to cease moving.
