A gentleman is preparing to board a plane, when he hears that the Pope is on the same flight. “This is exciting,” thinks the gentleman. “Perhaps I'll be able to see him in person.” Imagine his surprise when the Pope sits down in the seat next to him. Shortly after take-off, the Pope begins a crossword puzzle. Almost immediately, the Pope turns to the gentleman and says, “Excuse me, but do you know a four letter word referring to a woman that ends in ‘unt?’” Only one word leaps to mind. “My goodness,” thinks the gentleman, “I can't tell the Pope that. There must be another word.” The gentleman thinks for quite a while, and then it hits him. Turning to the Pope, the gentleman says, “I think the word you're looking for is ‘aunt.’” “Of course,” says the Pope. “Do you have an eraser?”

Alexander Parkes

Died 29 Jun 1890 at age 76 (born 29 Dec 1813).British industrial chemist who invented many processes. Parkes was an expert in electroplating, able to silver-plate such diverse objects as a spider web and flowers. He patented a method of rubber coating fabrics to waterproof them (1841), an electroplating process (1843), and a method of extracting silver from lead ore by adding zinc (1850). He produced the first plastic (1855), which he called Parkesine, by dissolving cellulose nitrate in alcohol and camphor containing ether. The hard solid result could be molded when heated, but he could find no market for the material. (This was rediscovered in the 1860s by John Wesley Hyatt, an American chemist, who named it celluloid and successfully marketed it as a replacement for ivory.«
