Mr. Thompson Westcott, the author, is perfectly at home on this subject, having written "The Guide Book to Philadelphia," and a history of the city. In the present volume, he has given a description of all the interesting historic buildings of the city, e.g. Penn's Cottage, Swedes' Church, Bartram's House, Christ Church, Independence Hall, the Slate Roof House or Mount Pleasant, together with a notice of their owners and occupants.
