Brave captain
One fine day, brave Captain Smith and his crew of sailors were sailing the ocean blue.
Suddenly, on the horizon, there loomed a ship with a skull and crossbones raised on the mast.
The crew was frantic, seeking refuge and asking the captain what to do.
Brave Captain Smith looked at the approaching ship for a moment and said, "Bring me my red shirt."
The call was taken up at once by a cabin boy. As soon as Captain Smith had the shirt in his possession, he ordered the man at the wheel to head straight for the pirate ship.
In the ensuing fight, the pirate ship was all but destroyed.
The sailors were recounting their individual triumphs afterwards when someone asked Captain Smith why he had asked for his red shirt before the battle.
He responded: "If I was wounded, I did not want your confidence to wane. This way, you would keep fighting no matter what happened to me."
The crew had a new found admiration for its captain, and they talked all night about his bravery.
About a week later, there loomed on the horizon 10 pirate ships. Once again, the crew looked to its captain for leadership.
Calmly, Captain Smith said, "Boys, bring me my brown pants!"

Guillaume RondeletDied 30 Jul 1566 at age 58 (born 27 Sep 1507).French naturalist and physician who contributed substantially to zoology by his descriptions of marine animals, primarily of the Mediterranean Sea. After studying at Montpellier, he later travelling widely through Europe with his patron Cardinal Tournon. Returning to Montpellier in 1545, he taught medicine. His real interest, however, was zoology, and in 1554 he published his massive compendium on aquatic life, Libri de piscibus marinis in quibus verae piscium effigies expressae sunt, which covered far more marine life than any earlier work in the field. This laid the foundation for later ichthyological research and was the standard reference work for over a century. He also published various other works on diagnosis and several pharmacological works. |
