On my first day in London I made an early start. Reaching the Public Record Office not much after ten, I soon secured the papers I needed for my research and settled in my place. I became, as is the way of the scholar, so deeply absorbed as to lose all consciousness of my surroundings or of the passage of time. When at last I came to myself, it was almost eleven and I was quite exhausted: I knew I could not prudently continue without refreshment.
