on natural philosophy by the itinerant lecturer Stephen Demainbray. This led to an interest in natural philosophy on the part of the young prince and may have led to George III's collection of natural philosophical instruments. Bute furthermore became close to Prince Frederick's widow, Augusta of Saxe-Gotha, the Dowager Princess of Wales, and it was rumoured that the couple were having an affair. Indeed, one of the Prince of Wales's associates, John Horne Tooke, published a scandalous pamphlet alluding to the liaison, but the rumours were almost certainly untrue, since Bute held sincere religious beliefs against adultery and, by all indications, appeared happily married.
