I cannot omit to add hereunto another experiment, which is, that we find by the effects, how the rayes of the moon are cold and moist. ... The beams then which come from the moon, are those of the sun, which glancing upon her, reflect upon us, and so bring with them the atoms of that cold and humid star, which participates of the source whence they come: therefore if one should expose a hollow bason, or glass, to assemble them, one shall find, that whereas those of the sun do burn by such a conjuncture, these clean contrary do refresh and moisten in a notable manner, leaving an aquatic and viscous glutining kind of sweat upon the glass. One would think it were a folly that one should offer to wash his hands in a well-polished silver bason, wherein there is not a drop of water, yet this may be done by the reflection of the moonbeams only, which will afford a competent humidity to do it; but they who have tried this, have found their hands, after they are wiped, to be much moister than usually: but this is an infallible way to take away warts from the hands, if it be often used.- Sir Kenelme Digby, Late Discourse, &c., Touching the Cure of wounds by the Powder of Sympathy. 1658.
