that quality in bodies whereby they are capable of wetting other bodies. This differs very much from fluidity, and seems to be merely a relative thing, depending upon the congruity of the component particles of the liquor to the pores of such particular bodies, as it is capable of adhering to, penetrating a little into, or wetting.
