LIQUID FLOWERS IN ICE.

leaves were unbroken curves, but when the flowers expanded
under a long-continued action, the edges became serrated.
When the ice was held at a suitable angle to the solar
beams, these liquid blossoms, with their central spots
shining more intensely than burnished silver, presented
an exhibition of beauty not easily described. I have given
a sketch of their appearance in Fht 34.
I have here to direct attention to an extremely curious
fact. On sending the sunbeam through the transparent
ice, I often noticed that the appearance of the lustrous
spots was accompanied by an audible clink, as if the ice
were ruptured inwardly. But there is no ground for
assuming such rupture, and on the closest examination
no flaw is exhibited by the ice. What then can be the
cause of the noise ? I believe the following considerations
will answer the question:—
Water always holds a quantity of air in solution, the
diffusion of which through the liquid!, as proved by M.
Donny, has an immense effect in weakening the cohesion
of its particles; recent experiments of my own show that
this is also the case in an eminent degree with many
volatile liquids. M. Donny has proved that, if water be
thoroughly purged of its air, a long glass tube filled with
