原文
E Hoaxes are a further aspect of the playfulness of scientists. A relatively recent example concerns the 'Plate of Brasse', which stated England's claim to California and was supposedly left by the English navigator Sir Francis Drake during his visit in 1579. A brass plate thought to be Drake's was discovered in the 1930s. But in 1977, Helen Michel and Frank Asaro, of the Lawrence Berkeley National Laboratory, showed that the copper and zinc used in the plate were of a higher quality than would have been available in the 1500s. They concluded that Drake's plate was most likely crafted much closer to the time when it was first brought to light.
F Shortly afterwards, staff at the University of California announced that the artefact was devised as a practical joke by a group of friends of Herbert E Bolton, who directed the Bancroft Library at the University's Berkeley campus. Bolton, it seems, was intrigued by tales of Drake having installed a plate to record his visit to California, and often urged his students to look for it. Some of Bolton's friends decided to play a joke on him, but things misfired after Bolton went public and announced that the relic was authentic before he could be told about the joke.
