Oxfordshire.
Pointer, in his Oxoniensis Academia (1749, p. 20), says that, at Merton College, Oxford, the fellows meet together in the Hall on Christmas Eve and other solemn times to sing a psalm and drink a grace-cup to one another (called Poculum Charitatis), wishing one another help and happiness. These grace-cups they drink to one another every day after dinner and supper, wishing one another peace and good neighbourhood.
