Long ago, operatioon had usually to be done while the sick man
could feel everything. The sick man had to be held down on a table
by force while the doctors did their best for him. He could feel
all the pain if his leg or arm was being cut off, and his fearful cries
filled the room and the hearts of those who watched.
Soon after 1770, Josept Priestley discovered a gas which is now
called " Laughing gas " Laughing gas became known in America. Young
men and women went to parties to try it. Most of them spent their time
laughing, but one man at a party, Horace Wells, noticed that people did
not seem to feel pain when they were using the gas. He decided to make
an experiment on himself. He asked a friend to help him.
Wells took some of the gas, and his friend pulled out one of Well'seeth.
Wells felt no pain at all.
As he did not know enough about laughing gas , he gave a man less gas
than he should have. The man cried out with pain when his tooth was
being pulled out.
Wells tried again, but this time he gave too much of the gas , and the
man died. Wells never forgot this terrible event.
