Abstract
IN connection with the discussion on the formation of ice in crystals, it might be worth while to record that on December 6, 1861, in a slight frost, I saw some in the process of formation in a trough of water. There were three thin pieces of ice in it, two irregular, but the third a beautiful star, 4 or 5 inches in diameter, having six feather-like rays which were branched twice or thrice, in all cases at an angle of 60°. Also, two days before, when the water in the trough was frozen over, I observed in it six-rayed stars several inches in diameter very slightly raised above the rest of the surface.
