force into his mouth then lifted up and open, and in such a quantity, as to cover not only his face, but all his clothes." Dr. Spry's account was received with such scepticism by The Royal Society that he felt constrained to conduct experiments on dogs and chickens, pouring melted lead down the animals' throats, to prove that it was possible to survive, for at least a limited period, such an extreme accident. Legacy There is a small plaque dedicated to Henry Hall with a few details as to the nature of this death located in Plymouth city centre, set into the pavement between Plymouth Pavilions, Salumi Bar & Eatery and The Duke of Cornwall Hotel, Millbay Road. The piece of lead found in Henry Hall's stomach is now kept in the National Museum of Scotland.
