Excerpt from Heat Production of Honeybees in Winter In considering the circumstances on this last day-of the experi ment with bees it is interesting to recall observations made in the study Of the effect Of ventilation on men, that the sensations produced by bad 7air are not experienced when the air is stirred. If this indicates an actual cliflerence in physiological conditions in the di mer ent circumstances, then it is not inconceivable that something analo gous to this was true Of the bees on this day. The stirring Of the air when the circulation was resumed may have served to remove some cause Of depression that was e mective when the circulation was stopped.'
