[…] the awfully hearty sort of Christmas cards that people do send to other people that they don't know at all well.

I launched out in search of a vegetarian restaurant. […] I would trot ten or twelve miles each day, go into a cheap restaurant and eat my fill of bread, but would never be satisfied. During these wanderings I once hit on a vegetarian restaurant in Farringdon Street. The sight of it filled me with the same joy that a child feels on getting a thing after its own heart. Before I entered I noticed books for sale exhibited under a glass window near the door. I saw among them Salt's Plea for Vegetarianism. This I purchased for a shilling and went straight to the dining room. This was my first hearty meal since my arrival in England.
