Famous quotes containing the word ferdinand:
“I fairly confess that, acting as nature and simplicity dictated, no sooner did I see the once loved bosom of my Ferdinand free from those deformed demons which had crept in and filled up the vacant space, than beholding my natural home once more the seat of innocence and truth, my heart joyfully danced into its delightful abode.”
—Sarah Fielding (1710–1768)
