I cannot take leave of this ball without communicating to you a circumstance which occurred there, and which, from the extravagant credulity it exhibits in regard to the effects of sympathy, may possibly amuse you for a moment. A widow, about twenty years of age, more to be admired for the symmetry of her person, than for the beauty of her features, had, according to the prevailing custom, intrusted her pocket-handkerchief to the care of a male friend, a gentlemanlike young Frenchman of my acquaintance. After dancing, the lady finding herself rather warm, applied for her handkerchief, with which she wiped her forehead, and returned it to the gentleman, who again put it into his pocket. He then danced, but not with her; and, being also heated, he, by mistake, took out the lady's handkerchief, which, when applied to his face, produced, as he fancied, such an effect on him, that, though he had previously regarded her with a sort of indifference, from that moment she engaged all his attention, and he was unable to direct his eyes, or even his thoughts, to any other object. Some philosophers, as is well known, have maintained that from all bodies there is an emanation of corpuscles, which, coming into contact with our organs, make on the brain an impression, either more or less sympathetic, or of a directly-opposite nature. They tell you, for instance, that of two women whom you behold for the first time, the one the least handsome will sometimes please you most, because there exists a greater _sympathy_ between you and her, than between you and the more beautiful woman. Without attempting to refute this absurd doctrine of corpuscles, I shall only observe that this young Frenchman is completely smitten, and declares that no woman in the world can be compared to the widow.
