Endometriosis (say en-doh-mee-tree-OH-sus) is a problem many women have during their childbearing years. It means that a type of tissue that lines your uterus is also growing outside your uterus. This does not always cause symptoms. And it usually isn't dangerous.
A massive bell was required and the first attempt (made by John Warner & Sons at Stockton-on-Tees) cracked irreparably. The metal was melted down and the bell recast in Whitechapel in 1858. Big Ben first rang across Westminster on 31 May 1859. A short time later, in September 1859, Big Ben cracked.
Big Ben was the name originally given to the largest of the clock towerâs bells. The Great Bell, as it is otherwise known, weighs 13 tons (13,760 kilograms). Listen for its deep knell as it strikes on the hour, peeling high across the rooftops and rush of Londonâs traffic. Nowadays, the name Big Ben is synonymous with the bells, the clock and the tower.
