Passage: For George III, Pitt's appointment was a great victory. It proved that he was able to appoint Prime Ministers on the basis of his own interpretation of the public mood without having to follow the choice of the current majority in the House of Commons. Throughout Pitt's ministry, George supported many of Pitt's political aims and created new peers at an unprecedented rate to increase the number of Pitt's supporters in the House of Lords. During and after Pitt's ministry, George III was extremely popular in Britain. The British people admired him for his piety, and for remaining faithful to his wife. He was fond of his children, and was devastated at the death of two of his sons in infancy in 1782 and 1783 respectively. Nevertheless, he set his children a strict regimen. They were expected to attend rigorous lessons from seven in the morning, and to lead lives of religious observance and virtue. When his children strayed from George's own principles of righteousness, as his sons did as young adults, he was dismayed and disappointed.By this time George's health was deteriorating. He had a mental illness, characterised by acute mania, which was possibly a symptom of the genetic disease porphyria, although this has been questioned. A study of samples of the King's hair published in 2005 revealed high levels of arsenic, a possible trigger for the disease. The source of the arsenic is not known, but it could have been a component of medicines or cosmetics. The King may have had a brief episode of disease in 1765, but a longer episode began in the summer of 1788. At the end of the parliamentary session, he went to Cheltenham Spa to recuperate. It was the furthest he had ever been from London—just short of 100 miles (150 km)—but his condition worsened. In November he became seriously deranged, sometimes speaking for many hours without pause, causing him to foam at the mouth and making his voice hoarse. George would frequently repeat himself, and write sentences with over 400 words at a time, as well as his vocabulary...
