Note particularly how Avicenna says that it is not proper to administer pills when they have become dry, when they are like stones, or when they are soft; but when they commence to dry, and when they yield before the fingers on being pressed.
The electuary: it is indeed proper to administer it at midnight between the hour for the pills and the hour for the liquid medicine, because it is easier to dissolve the electuary than the pills, and harder than the liquid medicine.
