For more than a century and a half Philadelphia has evinced a profound tendency toward studies in the natural sciences. Bartram's Botanical Garden was started in 1728, and Marshall's in 1773.

A further advance in higher education was made by opening the school to both sexes alike. In this school has been developed a complete system of education, different from but equal in value to the ordinary college course.
