| Description | Hicks writes: 'Silver may be extracted out of lead as well as out of tin. Leads may be melted and made good lead again, but tin cannot.' He writes briefly on the preservation of beef and pork using salt and on an experiment concerning how salts and acids can be 'sucked out of the blood by bathing in warm salt water', and asks whether someone with gout or other types of arthritis could safely perform this experiment.
