has a receipt to mar all his work in a moment, for by nailing the wrong end of a scutcheon upwards upon a gibbet all the honour and gentility extinguishes of itself, like a candle that's held with the flame downwards. Other arms are made for the spilling of blood, but his only purify and cleanse it like scurvy-grass; for a small dose taken by his prescription will refine that which is as base and gross as bull's blood (which the Athenians used to poison withal) to any degree of purity. A VIRTUOSO Is a well-willer to the mathematics; he pursues knowledge rather out of humour than ingenuity, and endeavours rather to seem than to be. He has nothing of nature but an inclination, which he strives to improve with industry; but as no art can make a fountain run higher than its own head, so nothing can raise him above the elevation of his own pole. He seldom converses but with men of his own tendency, and wheresoever he comes treats with all men as such; for as country gentlemen use to talk of their dogs to those that hate hunting because they love it themselves, so will he of his arts and sciences to those that neither know nor care to know anything of them. His industry were admirable if it did not attempt the greatest difficulties with the feeblest means; for he commonly slights anything that is plain and easy, how useful and ingenious soever, and bends all his forces against the hardest and most improbable, though to no purpose if attained to; for neither knowing how to measure his own abilities nor the weight of what he attempts, he spends his little strength in vain and grows only weaker by it; and as men use to blind horses that draw in a mill, his ignorance of himself and his undertakings makes him believe he has advanced when he is no nearer to his end than when he set out first. The bravery of difficulties does so dazzle his eyes that he prosecutes them with as little success as the tailor did his amours to Queen Elizabeth. He differs from a pedant as things do from words, for he uses the same affectation in his operations and experiments as the other does in language. He is a haberdasher of small arts and sciences, and deals in as many several operations as a baby artificer does in engines. He will serve well enough for an index to tell what is handled in the world, but no further. He is wonderfully delighted with rarities, and they continue still so to him though he has shown them a thousand times, for every new admirer that gapes upon them sets him a-gaping too. Next these he loves strange natural histories; and as those that read romances, though they know them to be fictions, are as much affected as if they were true, so is he, and will make hard shift to tempt himself to believe them first to be possible, and then he's sure to believe them to be true, forgetting that belief upon belief is false heraldry. He keeps a catalogue of the names of all famous men in any profession, whom he
