Jeroboam of Rum or Claret (A)
.Eight bottles; but of whisky three pints. Probably a perversion of “joram.” (See Tappit-hen and Rehoboam.)
“Some ‘jeroboamsʹ of very old rum went at 15s. each; several ‘tappit-hens, of rum fetched 34s. and some ‘magnums,ʹ 17s. each.”—Truth, 31st March, 1887.
A magnum = 2 quart bottles; a tappithen = 2 magnums; a jeroboam = 2 tappit-hens; and a rehoboam = 2 jeroboams or 16 quart bottles.
