“I beg to confirm my purchase of the first-floor room of the Electric Lighting Board at 7, Pall Mall, to view the procession on Thursday, June 26, for the sum of 141l. 15s., which amount is now due. I shall be obliged if you will take the room on sale, and I authorize you to sell separate seats in the room, for which I will erect a stand. If the seats thus sold in the ordinary way of business do not realize the above amount by June 26, I agree to pay you the balance to make up such amount of 141l. 15s.”
