Quotations
A mad world this, my friends, a world in its lunes, petty and other; in lunes other than petty now for some time; in petty-lunes, pettilettes, or pantalettes, about these six weeks, ever since when this rampant androgynous Bloomerism first came over from Yankee land. A sort of shemale dress you call Bloomerism; a fashion of Sister Jonathan's.
