Halley was there that day, and spoke up sharply, "Sir, there are hints and hints! Do you _mean_ more?" --"I do, sir," chirruped Samuel, mightily pleased To find all eyes, for once, on his fat face. "I fear his intellects are disordered, sir." --"Good! That's an answer! I can deal with that. But tell me first," quoth Halley, "why he wrote That letter, a week ago, to Mr. Pepys." --"Why, sir," piped Samuel, innocent of the trap, "I had an argument in this coffee-house Last week, with certain gentlemen, on the laws Of chance, and what fair hopes a man might have Of throwing six at dice. I happened to say That Mr. Isaac Newton was my friend, And promised I would sound him." "Sir," said Halley, "You'll pardon me, but I forgot to tell you I heard, a minute since, outside these doors, A very modish woman of the town, Or else a most delicious lady of fashion, A melting creature with a bold black eye, A bosom like twin doves; and, sir, a mouth Like a Turk's dream of Paradise. She cooed, 'Is Mr. Pepys within?' I greatly fear That they denied you to her!" Off ran Pepys! "A hint's a hint," laughed Halley, "and so to bed. But, as for Isaac Newton, let me say, Whatever his embroilments were, he solved With just one hour of thought, not long ago The problem set by Leibnitz as a challenge To all of Europe. He published his result Anonymously, but Leibnitz, when he saw it, Cried out, at once, old enemy as he was, 'That's Newton, none but Newton! From this claw I know the old lion, in his midnight lair.'" VI (_Sir Isaac Newton writes to Mrs. Vincent at Woolthorpe._)
