Webster 1828 Edition
1.A speech addressed to an assembly or an army; a popular oration; a public address. This word seems to imply loudness or declamation, and is therefore appropriated generally to an address made to a popular assembly or to an army, and not to a sermon, or to an argument at the bar of a court, or to a speech in a deliberative council, unless in contempt.
2.Declamation; a noisy, pompous or irregular address.
