As the respiration of Insects depends on abdominal movements, it 
may continue after the removal of the head. The number of respira- 
tions is increased by heat. Tobacco-smoke and chloroform lead to inter- 
mittent but more or less rhythmical respiration for a time. The head 
and prothorax may be removed, and the respiration will continue ; and 
if the abdomen of a dragon-fly is cut to pieces, respiration will continue 
in them, thus showing that each abdominal segment possesses its own 
respiratory centre.
