An empty bottle: so called at the university of Cambridge, where fellow commoners are not in general considered as over full of learning. At Oxford an empty bottle is called a gentleman commoner for the same reason. They pay at Cambridge 250 l. a year for the privilege of wearing a gold or silver tassel to their caps. The younger branches of the nobility have the privilege of wearing a hat, and from thence are denominated HAT FELLOW COMMONERS.
