"The gravity of my occupation compels me to exclude everyone, but you are an exception. Come whenever you like, you will be shewn in. You need not mention my name nor your own. I do not ask you to share my repast, far my food is not suitable to others—to you least of all, if your appetite is what it used to be."
At nine o'clock I paid my call, and found he had grown a beard two inches long. He had a score of retorts before him, full of liquids in various stages of digestion. He told me he was experimenting with colours for his own amusement, and that he had established a hat factory for Count Cobenzl, the Austrian ambassador at Brussels.
