Abstract
THE filamentous form of ice-crystal, described by the Duke of Argyll as occurring upon rotten wood when a frost sets in suddenly after moisture, is by no means uncommon also upon chalk and other porous kinds of stone. It appears to arise from the water with which the body is soaked being extruded by the expansion due to cold when near its freezing-point, and becoming solidified as it passes the surface of the substance. It is, as it were, spun out of the pores of the rotten wood or porous stone. This explanation accounts for the fact, noticed by his Grace, that this form of crystal is not found upon those parts of a decayed branch upon which the bark is unbroken.
