subs. (Christs Hospital).A biscuit given on St, Matthews Day. [Orthography dubious. Blanch inclines to the following derivation: The biscuit had once something to do with those nights when bread and beer, with cheese, were substituted for bread-and-butter and milk. Thence the term crug and aler. The only argument against this is the fact that the liquid was never dignified with the name of ale, but was invariably called the swipes. By another derivation = hard as nails. It is then spelt CRUGGY-NAILER.]
