What's the trick?

A man went to the police station wishing to speak with the burglar who had broken into his house the night before.

"You'll get your chance in court," said the desk sergeant.

"No, no, no!" insisted the man. "I want to know how he got into the house without waking my wife. I've been trying to do that for years!"

Carl Wilhelm Scheele

Born 9 Dec 1742; died 21 May 1786 at age 43. (also Karl) Swedish chemist who discovered oxygen in 1772. Scheele, a keen experimenter, worked in difficult and often hazardous conditions. In his only book, Chemical Observations and Experiments on Air and Fire (1777), he stated that the atmosphere is composed of two gases, one supporting combustion, which he named "fire air" (oxygen), and the other preventing it, which he named "vitiated air" (nitrogen). Due to delay in his publication, he lost priority to Priestley's discovery of oxygen in 1774. Scheele discovered many substances, such as chlorine (1774), manganese (1774), tungsten (1781), molybdenum (1782), glycerol, hydrocyanic (prussic) acid, citric acid, hydrogen sulphide and hydrogen fluoride. He also discovered a process resembling pasteurization.
