A little boy returning home from his first day at school said to his mother, "Mom, what's sex?"
His mother, who believed in all the most modern educational theories, gave him a detailed explanation, covering all aspects of the tricky subject.
When she had finished, the little lad produced an enrollment form which he had brought home from school and said, "Yes, but how am I going to get all that into this one little square?"
Centennial of ChemistryIn 1874, the Centennial of Chemistry in the U.S. was celebrated by chemists meeting at Northumberland, Pa. where Joseph Priestley was buried after spending the last years of his life in America. The chemists commemorated the 100th anniversary of Priestley's discovery of the element oxygen on 1 Aug 1774, regarded as the most important link in the chain of events which eventually led to the overthrow of the phlogistic hypothesis. The memorial exercises were planned to include an address by Professor Joseph Henry, an Essay on American Contributions to Chemistry by Benjamin Silliman, Jr., and a loan exhibition of Priestley's apparatus, books and manuscripts. The event was initiated by Henry Bolton.« |
