'Canine at the Westminster Pit', 1862.

'Canine at the Westminster Pit', 1862. Pit Bull terriers are set in a pit at Westminster. The one on the right is Derby, the dog of Lord Derby, the Conservative Leader. The one on the left is the Westbury Pup. This refers to an ongoing battle in parliament during which Lord Westbury was at odds with Lord Chelmsford. It stemmed from an omission in the new Bankruptcy Act which meant that some officials of the Insolvent Court had lost pay. However, when Lord Derby rose to intervene in the argument, Lord Westbury turned on him. According to Mr Punch, great fun was had by all, and the clerks at the centre of the row would simply have to wait a little longer for their case to be resolved. From Punch, or the London Charivari, March 29, 1862. (Photo by The Cartoon Collector/Print Collector/Getty Images)
