content: This glass tube with brass fittings at either end showed that, in a vacuum, heavy and light objects fall with the same rate of speed. The form came into use for science demonstrations in the early eighteenth century. This example was used at Saint Joseph’s Academy and Free School, in Emmitsburg, Md. Established by Elizabeth Ann Seaton, shortly after her arrival at Emmitsburg in 1809, this was the first free parochial school for girls in the United States.
