Upon this invitation, I drank of my visitor’s tankard; and believe me, reader, I never yet tasted any thing half so delicious; for it fully equalled the eulogium which Shakspeare’s jovial knight pronounces upon it in the Second part of “_King Henry the Fourth_,” Act iv. sc. iii.; where the merry Cavalier of Eastcheap tells us, that “a good Sherris sack hath a two-fold operation in it: it ascends me into the brain, dries me there all the foolish, and dull, and crudy vapours which environ it: makes it apprehensive, quick, forgetive, full of nimble, fiery, and delectable shapes; which, delivered o’er to the voice, (the tongue,) which is the birth, becomes excellent wit. The second property of your excellent Sherris is,--the warming of the blood; which, before cold and settled, left the liver white and pale, which is the badge of pusillanimity and cowardice: but the Sherris warms it, and makes it course from the inwards to the parts extreme. It illumineth the face; which, as a beacon, gives warning to all the rest of this little kingdom, man, to arm; and then, the vital commoners, and inland petty spirits, muster me all to their Captain, the heart; who, great, and puffed up with this retinue, doth any deed of courage; and this valour comes of Sherris: so that skill in the weapon is nothing, without Sack: for that sets it a-work: and learning, a mere hoard of gold kept by a devil, till Sack commences it, and sets it in act and use.--If I had a thousand sons, the first human principle I would teach them, should be,--to forswear thin potations, and addict themselves to Sack!” Truly, indeed, I felt all those effects in myself; whilst my visitor appeared to be so inspired by it, that, as if all the valuable lore relating to London Bridge had been locked up until this moment, he opened to me such a treasure of information concerning it, that, I verily believe, he left nothing connected with the subject untouched. He quoted books and authors with a facility, to which I have known no parallel; and, what is quite as extraordinary, the same magical philtre enabled me as faithfully to retain them. Indeed, the posset and his discourse seemed to enliven all my faculties in such a manner, that the very scenes of which my companion spake, appeared to rise before my eyes as he described them. When Mr. Postern had pledged me, therefore, by drinking my health, in a very formal manner, he thus commenced his discourse.
