Justin McCarthy,
A History of the Four Georges and of William IV, Volume III
“ Pitt was slender, boyish, precise, punctilious in attire, his native composure only occasionally lightened by a flash of humor or sweetened by a show of playfulness, old beyond his years and young to the end of his short life, sternly self-restrained and self-commanded, gracious in a kind of melancholy, unconscious charm, a curiously unadorned, uncolored personality, that attracted where it did attract with a magnetism that was perhaps all the more potent for being somewhat difficult to explain. Fox was always a lover in many kinds of love, fugitive, venal, illicit, honorable, and enduring. ”
