 by the escape of air into the celluhir tissue, as between the skin

 tures on the surface of the swelling, assisted by gentle jiressure of 

 the hand. 



When in the lungs, give good feeding, and occasionally small 

 doses of the tincture of aconite root, say 10 drops, three times in 

 the day, to relieve the breathing, until the lungs heal up.
