In case of threatened asphyxia the dernier resort of trache- 

 otomy is always available, and this ofteti acts very favorabl}' in 

 improving the aeration of the blood, in restoring the flagging 

 vital functions which depend on haematosis, and in removing the 

 friction and irritation consequent on the passage of air through 

 the narrowed and tender passages.
