EXAUCTORATIO, in the Roman military discipline, differed from the missio, which was a full discharge, and took place after soldiers had served in the army 20 years; whereas the exauctoratio was only a partial discharge: they lost their pay indeed, but still kept under their colors or vexilla, though not under the aquila or eagle, which was the standard of the legion: whence instead of legionarii, they were called subsignani, and were retained till they had either served their full time, or had lands assigned them. The exauctoratio took place after they had served 17 years.

EXCELLENCY, a title absurdly given to kings and emperors, in Europe, and with equal falsehood and absurdity given to governors, ambassadors, generals, and other persons.
