“As the opening of the trial record noted, ‘The report has now become well known in many places that this woman, utterly disregarding what is honourable in the female sex, breaking the bounds of modesty, and forgetting all female decency, has disgracefully put on the clothing of the male sex, a striking and vile monstrosity.
