Water and Whiskey

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, closely observe the worms," said the professor while putting a worm into the water.
The worm in the water writhed about, happy as a worm in water could be. He then put the second worm into the whiskey. It curled up and writhed about painfully, then quickly sank to the bottom, dead as a doornail.
"Now, what lesson can we learn from this experiment?" the professor asked.

Johnny, who naturally sits in back, raised his hand and wisely, responded confidently, "Drink whiskey and you won't get worms."

Albert S. Bickmore

Died 12 Aug 1914 at age 75 (born 1 Mar 1839).Albert Smith Bickmore was an American naturalist, traveller and museum curator who acquired his love of natural history as a result of growing up in a coastal town. He studied natural history under Professor Agassiz, and shortly also began to care for the department of Mullusca at the Museum of Comparative Zoology at Harvard University. There he conceived the idea of the American Museum of Natural History. By 1865, he set off on a three-year expedition to the East Indies, China, Japan, Russia and Europe gathering specimens to form the basis of the future museum's collection. Upon his return, he devoted himself to indeed establishing the institution, and was able to arrange for its funding. He wrote of his travels in Travels in the East Indian Archipelago (1869). In 1870, he was appointed Professor Natural History at Madison University, Hamilton, New York. The cornerstone of the new building was laid on 2 Jun 1874, by President Grant.«
