In 1903, anti-vivisectionists enrolled as medical students at University College London and published an eyewitness account of a brown dog that had endured months of surgical experimentation while allegedly conscious. A professor named in the story sued for defamation and won. After the trial, anti-vivisectionists put up a statue of the dog as a monument in a park, but mobs of angry medical students rioted and tried to destroy it. In 1910, it was taken down by authorities. When was it replaced? Discuss
