He described the administration of this preparation to hens that fell into what appeared to be a deep sleep from which they recovered unharmed. In 1735, Wilhelm Froben gave this substance its modern name of “ether.” Ether was used topically, particularly via the intranasal route, as a treatment of headache, nervous diseases, and fits.
