Two cows....

Two cows were chatting over the fence between their fields. The first cow said, "I tell you, this mad-cow-disease is really pretty scary. They say it is spreading fast; I heard it hit some cows down on the Johnson Farm."

The other cow replied, "Ah, I ain't worried, it won't affect us ducks."

Auguste Laurent

Born 14 Nov 1807; died 23 Apr 1853 at age 45. French chemist who developed organic chemistry as a distinct science. For a while, he assisted Jean Dumas, and extended his work, understanding organic compounds as derivatives of hydrocarbon molecules. In crystallography he was influenced by René-Just Haüy. Laurent recognised that carbon atoms formed bonds based on a pyramid structure. Furthermore, against the opinion of many peers, he rejected the idea held by Jöns Berzelius that even organic molecules were formed from positively and negatively charged entities. Laurent showed (1836) that a supposedly positive-charge hydrogen atom could be replaced by a supposedly negative-charge chlorine atom. He recognised families of organic compounds with characteristic groups. He died in middle age from tuberculosis.«
