Note 1 — HOME STUDIES IN CHEMISTRY AND PHYSICS.

Transcriber’s Note: This note was omitted in the original. Wikipedia has to say: “In general in ancient Greece, each state, city or village possessed its own central hearth and sacred fire, representing the unity and vitality of the community. The fire was kept alight continuously, tended by the king or members of his family. The building in which this fire was kept was the Prytaneum, and the chieftain (the king or prytanis) probably made it his residence.”
