invigilatrix

— A History paper was lately set, at a girls’ school, on a certain period of English history—say the Reformation. One question was: “Mention the person in your period who interests you most, and give your reasons.” During the examination some female præpostor or other subaltern was sitting with the girls, some of whom asked, “Does ‘your period’ mean our period?” “Yes,” said the invigilatrix, if that is the word for the fair looker-on.
