Boulton, at Plengwarry, to Watt, at Birmingham, 14th September, 1780. This day was Boulton’s birthday, and alluding to the circumstance he wrote,—“As sure as there are 1728 inches in a cubic foot, so sure was I born in that year; and as sure as there are 52 weeks in the year and 52 cards in the pack, so surely am I 52 years old this very day. May you and Mrs. Watt live very long and be very happy.”
