Reading edition
During his Scotch visit, Watt spent much of his time in arranging his father’s affairs, which had got into confusion. He was now seventy-five years old, and grown very infirm. “He is perfectly incapable,” wrote his son, “of giving himself the least help, and the seeing him in such a situation has much hurt my spirits.”—Watt to Boulton, 28th July, 1766.
