10 pm .-- I have visited him again and found him sitting in a corner brooding.

When I came in he threw himself on his knees before me and implored me to let him have a cat, that his salvation depended upon it.

I shall see him in the morning early.
20 July .-- Visited Renfield very early, before attendant went his rounds.
