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.
