+I learn in this letter that Don Peter of Arragon\n\
+comes this night to Messina\n\
+MESSENGER\n\
+He is very near by this: he was not three leagues off\n\
+when I left him\n\
+LEONATO\n\
+How many gentlemen have you lost in this action?\n\
+MESSENGER\n\
+But few of any sort, and none of name\n\
+LEONATO\n\
+A victory is twice itself when the achiever brings\n\
+home full numbers. I find here that Don Peter hath\n\
+bestowed much honour on a young Florentine called Claudio\n\
+MESSENGER\n\
+Much deserved on his part and equally remembered by\n\
+Don Pedro: he hath borne himself beyond the\n\
+promise of his age, doing, in the figure of a lamb,\n\
+the feats of a lion: he hath indeed better\n\
+bettered expectation than you must expect of me to\n\
+tell you how\n\
+LEONATO\n\
+He hath an uncle here in Messina will be very much\n\
+glad of it.\n\
+MESSENGER\n\
+I have already delivered him letters, and there\n\
+appears much joy in him; even so much that joy could\n\
+not show itself modest enough without a badge of\n\
+bitterness.\n\
+LEONATO\n\
+Did he break out into tears?\n\
+MESSENGER\n\
+In great measure.\n\
+LEONATO\n\
+A kind overflow of kindness: there are no faces\n\
+truer than those that are so washed. How much\n\
+better is it to weep at joy than to joy at weeping!\n\
+BEATRICE\n\
+I pray you, is Signior Mountanto returned from the\n\
+wars or no?\n\
+MESSENGER\n\
+I know none of that name, lady: there was none such\n\
+in the army of any sort.\n\
+LEONATO\n\
+What is he that you ask for, niece?\n\
+HERO\n\
+My cousin means Signior Benedick of Padua.\n\
+MESSENGER\n\
+O, he's returned; and as pleasant as ever he was.\n\
+BEATRICE\n\
+He set up his bills here in Messina and challenged\n\
+Cupid at the flight; and my uncle's fool, reading\n\
+the challenge, subscribed for Cupid, and challenged\n\
+him at the bird-bolt. I pray you, how many hath he\n\
+killed and eaten in these wars? But how many hath\n\
+he killed? for indeed I promised to eat all of his killing.\n\
+LEONATO\n\
+Faith, niece, you tax Signior Benedick too much;\n\
+but he'll be meet with you, I doubt it not.\n\
+MESSENGER\n\
+He hath done good service, lady, in these wars.\n\
+BEATRICE\n\
+You had musty victual, and he hath holp to eat it:\n\
+he is a very valiant trencherman; he hath an\n\
+excellent stomach.\n\
+MESSENGER\n\
+And a good soldier too, lady.\n\
+BEATRICE\n\
+And a good soldier to a lady: but what is he to a lord?\n\
+MESSENGER\n\
+A lord to a lord, a man to a man; stuffed with all\n\
+honourable virtues.\n\
+BEATRICE\n\
+It is so, indeed; he is no less than a stuffed man:\n\
+but for the stuffing,--well, we are all mortal.\n\
+LEONATO\n\
+You must not, sir, mistake my niece. There is a\n\
+kind of merry war betwixt Signior Benedick and her:\n\
+they never meet but there's a skirmish of wit\n\
+between them.\n\
+BEATRICE\n\
+Alas! he gets nothing by that. In our last\n\
+conflict four of his five wits went halting off, and\n\
+now is the whole man governed with one: so that if\n\
+he have wit enough to keep himself warm, let him\n\
+bear it for a difference between himself and his\n\
+horse; for it is all the wealth that he hath left,\n\
+to be known a reasonable creature. Who is his\n\
+companion now? He hath every month a new sworn brother.\n\
+MESSENGER\n\
+Is't possible?\n\
+BEATRICE\n\
+Very easily possible: he wears his faith but as\n\
+the fashion of his hat; it ever changes with the\n\
+next block.\n\
+MESSENGER\n\
+I see, lady, the gentleman is not in your books.\n\
+BEATRICE\n\
+No; an he were, I would burn my study. But, I pray\n\
+you, who is his companion? Is there no young\n\
+squarer now that will make a voyage with him to the devil?\n\
+MESSENGER\n\
+He is most in the company of the right noble Claudio.\n\
+BEATRICE\n\
+O Lord, he will hang upon him like a disease: he\n\
+is sooner caught than the pestilence, and the taker\n\
+runs presently mad. God help the noble Claudio! if\n\
+he have caught the Benedick, it will cost him a\n\
+thousand pound ere a' be cured.\n\
+MESSENGER\n\
+I will hold friends with you, lady.\n\
+BEATRICE\n\
+Do, good friend.\n\
+LEONATO\n\
+You will never run mad, niece.\n\
+BEATRICE\n\
+No, not till a hot January.\n\
+MESSENGER\n\
+Don Pedro is approached.\n\
+Enter DON PEDRO, DON JOHN, CLAUDIO, BENEDICK, and BALTHASAR\n\
+\n\
+DON PEDRO\n\
+Good Signior Leonato, you are come to meet your\n\
+trouble: the fashion of the world is to avoid\n\
+cost, and you encounter it\n\
