Moss of an Human Skull.
Muscus ex cranio humano.
There is not any particular kind of moss that grows upon the human skull, nor does any moss by growing upon it acquire any particular virtues, whatever fanciful people may have imagined. In England, we commonly use the moss just described, when it happens to run over an human skull, that has been laid by accident, or has been laid on purpose in its way: in other places, they use the sort of white moss, that grows upon our old apple trees. Both these are in their own nature astringents, but they are as good if taken from trees, or off the ground, as if found upon these bones. They have been supposed good against disorders of the head, when gathered from the skull, but this is all fancy.
