pieces OF ice placed III contact froze to-
gether almost instantly. Dir. Tyndall says,
| "one hot summer day / entered shop on
the Stand; in the window fragments of ice
were lying in basin. The tradcsman
gave me permission to take the pieces OF
Ice IN my own hand; holding the first piece
attached all the o. her pieces in tue BASIN
to it. The Thermometer was then sixty de.
Erces, and yet all the pieces were frozen
together. Sin this way Nlr. Tyndah form
cd chain OF ice. This experiment may
DC made even in hot water. Throw two
pieces OF ice in pail full of almost boiling
water. Keep them in contact and they will
| freeze together in despite of the high tenn.
pcrature. Dir. Faraday made an other ex-
pertinent of the same sort. He threw into
vessel 1uil OF water several small pieces

water. The moment one piece touched
another there was an instantaneous reirccZ-
ing Attraction soon brought all the pieces

An ice wheel turning on a surface of ice

inc rotation series OF cracks are heard
which show the eur that successive rcfrcc
zings are constantly taking place. The
phenomenon Of rcfreezing is easily explain
eli. AT the surface of piece of ice the
atoms, which are no longer in equilibrium
on the outside, tend to leave their neigh

Melting cnsucs. But if two pieces OF ice
arc brought together tho atoms on the sur
lace are restored to their equilibrium, tho
attractive action becomes what 1t was, the
atoms resume their relations with their
