Horace Walpole,
Memoirs of the Reign of King George the Second…
“ There the Duke of Newcastle was absolute. He had all the advice from wise heads that could make him get the better of rivals, and all the childishness in himself that could make them ashamed of his having got the better. If his fickleness could have been tied down to any stability, his power had been endless. Yet, as it often happens, the puny can shake, where the mighty have been foiled—nor Pitt, nor Fox, were the engines that made the Duke of Newcastle’s power totter. I have mentioned how early his petulant humour had humbled Legge—never was revenge more swiftly gratified. ”
