The liberty, indeed, which this young person allowed himself was, on one occasion, the means of bringing an imputation upon the poet's hospitality and good breeding, which, like every thing else, true or false, tending to cast a shade upon his character, was for some time circulated with the most industrious zeal. Without any authority from the noble owner of the mansion, he took upon himself to invite some Genevese gentlemen (M. Pictet, and, I believe, M. Bonstetten) to dine at Diodati; and the punishment which Lord Byron thought it right to inflict upon him for such freedom was, "as he had invited the guests, to leave him also to entertain them." This step, though merely a consequence of the physician's indiscretion, it was not difficult, of course, to convert into a serious charge of caprice and rudeness against the host himself. By such repeated instances of thoughtlessness (to use no harsher term), it is not wonderful that Lord Byron should at last be driven into a feeling of distaste towards his medical companion, of whom he one day remarked, that "he was exactly the kind of person to whom, if he fell overboard, one would hold out a straw, to know if the adage be true that drowning men catch at straws." A few more anecdotes of this young man, while in the service of Lord Byron, may, as throwing light upon the character of the latter, be not inappropriately introduced. While the whole party were, one day, out boating, Polidori, by some accident, in rowing, struck Lord Byron violently on the knee-pan with his oar; and the latter, without speaking, turned his face away to hide the pain. After a moment he said, "Be so kind, Polidori, another time, to take more care, for you hurt me very much."--"I am glad of it," answered the other; "I am glad to see you can suffer pain." In a calm suppressed tone, Lord Byron replied, "Let me advise you, Polidori, when you, another time, hurt any one, not to express your satisfaction. People don't like to be told that those who give them pain are glad of it; and they cannot always command their anger. It was with some difficulty that I refrained from throwing you into the water; and, but for Mrs. Shelley's presence, I should probably have done some such rash thing." This was said without ill temper, and the cloud soon passed away.
