when it freezes on a window panel
v. E. s.
A. Frost crystallizations have a
great variety and the formation of
each of the various types seems to
depend upon meteorological and
other conditions-some of them OBJ
scure. On window panes three types
generally form-the granular, crys-
talline and membranous. The last
variety forms only in heated rooms
on panes covered with an uncon-
gealed film of water, as dewlike
condensation of moisture. 1t occurs
most frequently in the form Of long
curving, featherlike ferns or a net
work of lines. This Is due to the
process of capitalization taking place
during the conversion of a film of
water into ice. The crystalline
variety forms only on panes that are
free from water in liquid form.
