This is their account
19 Octr 1775 The Morning was spent in Dressing, the Noon in going to Court, and the Evening was got rid of at the Play. We saw the young Princess Elizabeth dine first—her Attendant was only Madam de Guemené, who took her Plate from her to give it the page &c., but another Gentleman carved for Elizabeth is youngest Sister to the King, about twelve Years old or so, not handsome but passable, if She not so pinched in her Stays as makes her look pale & uneasy to herself. All Children through this Nation I perceive are thus squeezed and tortured during their early Years, and the Deformity they exhibit at maturity repays the stupid Parents for their Pains. The Princess herself suffers in Compliance to her Country's Taste.
