I became so engrossed in the County Sessions Rolls that I lost all count of time, and had quite a shock when I went in the Plaster Room to get a drink and was just in time to hear 4 o’clock striking. I thought well, thank goodness there’s only another four hours to daylight, and decided to go through one more volume before going to the Castle to get a little sleep.
