But where the nails are scabrous, they ought to be opened round, where they are joined to the flesh; then some of the following composition must be applied over them; of sandarach, sulphur, each p. ii. *. nitre, orpiment, each p. iv. *. liquid resin p. viii. *. And this is to be taken off on the third day. This medicine causes the spoiled nails to fall off and better to grow in their place.
