Article: London--A morning's train ride away, across the Channel, English kids talk about Liverpool's soccer team in a Paris puB.Some Parisians have even started to go to work in London.In the 19thcentury, Charles Dickens compared the two great rival cities, London and Paris, in " A Tale of Two Cities".These days, it might be A Tale of One City. Parisians are these days likely to smile in sympathy at a visitor's broken French and respond in polite English.As jobs grew lack at home over recent years, perhaps 250,000 Frenchmen moved across the Channel.With an undersea tunnel, they could travel between cities in three hours.The European Union freed them from immigration and customs. Paris, rich in beauty, is more attractive.But London feels more full of life, and more fun until the pubs shut down. "For me, the difference is that London is real, alive," said Trevor Wheeler, a banker. Chantal Jaouen, a professional designer, agrees."I am French, but I'll stay in London," she saiD. There is, of course, the other view.Julie Lenoux is a student who moved to London two years ago."I think people laugh more in Paris," she saiD. In fact, London and Paris, with their obvious new similarities, are beyond the old descriptions.As the European Union gradually loosened controls, Londoners _ into Paris to shop, eat and buy property . "Both cities have changed beyond recognition." Said Larry Collins, a writer and sometimes a Londoner.Like most people who know both well, he finds the two now fit together comfortably. "I first fell in love with Paris in the 1950s and it is still a wonderful place," Collins saiD."But if I had to choose, it would be London.Things are so much more ordered, and life is better." But certainly not cheaper.In fancy parts of London, rents can be twice those on Avenue Foch in Paris.Deciding between London and Paris requires a lifestyle choice. Like Daphne Benoit, a French journalism student with perfect English, many young people are happy to be close enough so they don't have to choose. "I love Paris, my little neighborhood, the way I can walk around a centre, but life is so structured," she saiD."In London, you can be who you want.No one cares."

Article: There are records of fingerprints taken many centuries ago. The ancient Babylonians pressed the tips of their fingerprints into clay to record business trade. The Chinese used ink-on-paper finger impressions for business. However, fingerprinting wasn't used as a method for identifying criminals until the 19th century. In 1858, Sir William Herschel was working as an official of the Hooghly district in Jungipoor, India.In order to reduce fraud , he had people living in the district record their fingerprints when signing business documents. A few years later, Scottish doctor Henry Faulds was working in Japan when he discovered fingerprints left by artists on ancient pieces of clay.This finding inspired him to begin investigating fingerprints.In 1880, Faulds wrote to his cousin, the famous naturalist Charles Darwin, and asked for help with developing a fingerprint classification system.Darwin refused, but sent the letter to his cousin, Sir Francis Gallon, who was an eugenicist . Gallon began collecting fingerprints and eventually gathered some 8, 000 different samples to analyze. In 1892, he published a book called "Fingerprints", in which he outlined a fingerprint classification system--the first existence. Around the same time, Juan Vucetich, a police officer in Buenos Aires, Argentina, was developing his own version of a fingerprinting system.In 1892, Vucetich was called in to assist with the investigation of the two boys murdered in Necoche, a village near Buenos Aires. Their mother, Francisca Rojas, accused a neighbour named Velasquez. But when Vucetich compared the fingerprints found at the murder scene to those of both Velasquez and Rojas, _ matched Rojas' exactly.She admitted her crime. This was the first time fingerprints had been used in a criminal investigation.Vucetich called his system comparative dactyloscopy . It's still used in many Spanish-speaking countries. Sir Edward Henry, in charge of the Metropolitan Police of London, soon became interested in using fingerprints to catch criminals. In 1896, he added to Gallon's technique, creating his own classification system, the Henry Classification System. It is the primary method of fingerprint classification throughout most of the world.
