Consult ‘The Lady’s Oracle’, a fortune-telling parlor game book from 1855.
Parlor games were often a means of covert flirtation and books like these would have been used in social situations, with the reader choosing a question and asking another person to choose a number from one to fifty in order to determine the answer. The answer corresponded to a bit of poetry and would be read aloud, likely to much amusement from the group.
