Punch, or the London Charivari, Volume 1, December 11, 1841

Essential as sulphuric acid is to the ignition of the platinum in an hydropneumatic lamp; so is half-and-half to the proper illumination of a Medical Student’s faculties. The Royal College of Surgeons may thunder and the lecturers may threaten, but all to no effect; for, like the slippers in the Eastern story, however often the pots may be ordered away from the dissecting-room, somehow or other they always find their way back again with unflinching pertinacity. All the world inclined towards beer knows that the current price of a pot of half-and-half is fivepence, and by this standard the Medical Student fixes his expenses. He says he has given three pots for a pair of Berlin gloves, and speaks of a half-crown as a six-pot piece.
Mr. Muff takes the goodly measure in his hand, and decapitating its “spuma” with his pipe, from which he flings it into Mr. Simpson’s face, indulges in a prolonged drain, and commences his narrative—most probably in the following manner:—
“You know we should all have got on very well if Rapp hadn’t been such a fool as to pull away the lanthorns from the place where they are putting down the wood pavement in the Strand, and swear he was a watchman. I thought the crusher saw us, and so I got ready for a bolt, when Manhug said the blocks had no right to obstruct the footpath; and, shoving down a whole wall of them into the street, voted for stopping to play at duck with them. Whilst he was trying how many he could pitch across the Strand against the shutters opposite, down came the pewlice and off we cut.”
“I had a tight squeak for it,” interrupts Mr. Rapp; “but I beat them at last, in the dark of the Durham-street arch. That’s a dodge worth being up to when you get into a row near the Adelphi. Fire away, Muff—where did you go?”
“Right up a court to Maiden-lane, in the hope of bolting into the Cider-cellars. But they were all shut up, and the fire out in the kitchen, so I ran on through a lot of alleys and back-slums, until I got somewhere in St. Giles’s, and here I took a cab.”
