History buffs might recall that a British Navy surgeon concluded (shortly before 1750) that sailors could reduce the incidence of painful and debilitating scurvy by sucking on limes. Concurrent experiments involving sailors taking vinegar or sea water failed. Eighteenth century medicine was unaware that limes contained Vitamin C (a substance not really understood until the 1930s) and also did not fully comprehend scurvy as a nutritional disease, but crews were issued limes in their rations after the field study. British sailors and later British people generally were nicknamed "limeys" shortly afterward. At the film's dock set, around a peck of sucked-on cut limes litter the ground as if discarded by sailors.
Half-fed slaves building our nation's Capitol. What possible good can come from such a place?
When arriving at St. James's Palace in 1785, John Adams and the audience glance up to see the Union Flag (same as the Union Jack, but on land). As a royal palace, the Union Flag would not have flown there before 1997. As His Majesty was present, the Royal Standard would have flown; in his absence, the flagstaff would have been bare. Prompted by the controversy over the propriety of showing remorse over the death of Diana, Princess of Wales, British royal vexillological protocol was altered in 1997 such that the Union Flag now flies over royal residences when the monarch is absent; however, the Royal Standard still flies in place of the Union Flag when the sovereign is present.
