[Footnote !: There is a curious passage from Aurelius, a writer on Law, on the Praetorian Praefect, quoted in Lydus de Magistratibus, p. 32, edit. Hase. The Praetorian praefect was to the emperor what the master of the horse was to the dictator under the Republic. He was the delegate, therefore, of the full Imperial authority; and no appeal could be made or exception taken against his edicts. I had not observed this passage, when the third volume, where it would have been more appropriately placed, passed through the press. - M]
