Note to Hamlet, 2.1.8-9: "And how, and who, what means, and where they keep, / What company, at what expense"

And how, and who, what means, and where they keep, / What company, at what expense: i.e., and how they came to Paris, and who they are, and what sources of income they have, and where they stay, and what company they keep, and how much money they spend.
