Nothing but Angostura bitters will do.

Livy my darling, I want you to be sure & remember to have, in the bath-room Ⓐemendation, when I arrive, a bottle of Scotch whisky, a lemon, & some crushed sugar, & a bottle of Angostura bitters. Ever since I have been in London I have taken in a wine-glass what is called a cock-tail (made with those ingredients,) before breakfast, before dinner, & just before going to bed.1explanatory note It was recommend mled by the surgeon of the “City of Chester” & was a most happy thought.2explanatory note To it I attribute the fact that up to this day my digestion has been wonderful—simply perfect. It remains day after day & week after week as regular as a clock. Now my dear, if you will give the order now, to have those things put in the bath-room & left there till I come, they will be there when I arrive. Will you? I love to write about arriving—it seems as if it were to be tomorrow. And I love to picture myself ringing the bell, at midnight—then a pause of a second or two—then the turning of the bolt, & “Who is it?”—then ever so many kisses—then you & I in the bath-room, I drinking my cock-tail & undressing, & you standing by—then to bed, and — —everything happy & jolly as it should be. I do love & honor you, my darling.
