Eccentricity in men of science is not rare. The Hon. Henry Cavendish, who demonstrated, in 1781, the composition of water, was a remarkable instance. He was an excellent mathematician, electrician, astronomer, and geologist; and as alchemist shot far ahead of his contemporaries. But he was a sort of methodical recluse, and an enormous fortune left him by his uncle did little to change his habits. His shyness and aversion to society bordered on disease. To be looked at or addressed by a stranger seemed to give him positive pain, when he would dart away as if hurt. At Sir Joseph Banks's _soirées_ he would stand for a long time on the landing, afraid to face the company. At one of these parties the titles and qualifications of Cavendish were formally recited when he was introduced to an Austrian gentleman. The Austrian became complimentary, saying his chief reason for coming to London was to see and converse with Cavendish, one of the greatest ornaments of the age, and one of the most illustrious philosophers that ever existed. Cavendish answered not a word, but stood with his eyes cast down, abashed, and in misery. At last, seeing an opening in the crowd, he flew to the door, nor did he stop till he reached his carriage and drove directly home. Any attempt to draw him into conversation was almost certain to fail, and Dr. Wollaston's recipe for treating with him usually answered best: "The way to talk to Cavendish is, never to look at him, but to talk as if it were into a vacancy, and then it is not unlikely you may set him going." Among the anecdotes which floated about it is related that Cavendish, the club Crœsus, attended the meetings of the Royal Society Club with only money enough in his pocket to pay for his dinner; that he declined taking tavern soup, picked his teeth with a fork, invariably hung his hat upon the same peg, and always stuck his cane in his right boot. More apocryphal is the anecdote that one evening Cavendish observed a pretty girl looking out from an upper window on the opposite side of the street, watching the philosophers at dinner. She attracted notice, and one by one they got up, and mustered round the window to admire the fair one. Cavendish, who thought they were looking at the moon, bustled up to them in his odd way, and when he saw the real object of attraction, turned away with intense disgust, and grunted out "Pshaw!" the more amorous conduct of his brother philosophers having horrified the woman-hating Cavendish.
