Aurora Tube
notes: label: Description
content: The two ends of this hollow glass aurora tube might be attached to an induction coil or static electrical machine. When there is air in tube, not much is seen; but as the air is evacuated, the electrical discharge becomes increasingly evident. The form originated in the 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.
