A professor of chemistry wanted to teach his 5th grade class a lesson about the evils of liquor, so he produced an experiment that involved a glass of water, a glass of whiskey, and two worms. "Now, class. Observe closely the worms," said the professor putting a worm first into the water. The worm in the water writhed about, happy as a worm in water could be. The second worm, he put into the whiskey. It writhed painfully, and quickly sank to the bottom, dead as a doornail. "Now, what lesson can we derive from this experiment?" the professor asked.
Johnny, who naturally sits in back, raised his hand and wisely, responded, "Drink whiskey and you won't get worms."

Marshall Hall

Died 11 Aug 1857 at age 67 (born 18 Feb 1790). English physiologist who was the first to advance a scientific explanation of reflex action. Although Hall earned his living as a practitioner, he was deeply interested in experimentation. A prolific writer, he wrote 19 books and more than 150 papers. Between 1824 and 1830, Hall published several papers and a book on the consequences of blood-letting. Hall published a pioneering book (1817) on diagnosis. In 1833, Hall described the mechanism by which a stimulus can produce a response independently of sensation or volition and coined the term "reflex" in the biological context. For the first time, the concept of the reflex arc was adopted as a basic mechanism of nervous disease, thus Hall may be called "the father of modern neurology."
