In 1847, Blackwell left Charleston for Philadelphia and New York, with the aim of personally investigating the opportunities for medical study.

As to the opinion of people, I don't care one straw personally; though I take so much pains, as a matter of policy, to propitiate it, and shall always strive to do so; for I see continually how the highest good is eclipsed by the violent or disagreeable forms which contain it.

The ballroom wing and a further suite of state rooms were also built in this period, designed by Nash's student Sir James Pennethorne.
