STUDENTS SOCIETY

The regular session of the Students So
ciety of the Latter-day Saints college con-
vened as usual last Friday evening, Feb.
ruary ID, Instructor j. J. Walton pre-
siding. After the opening exercises, a
mandolin and guitar selection was rendered
by Messrs. Hugh Dougall and George
Freeze. DR.. j. E. Talmage was then intro
duced, and his subject, 1.-THE Force of Co
hesion with demonstrations) The
speaker, after a few words of introduction,
first drew attention to the fact that all
matter possesses certain properties char
acteristic to itself, and that these proper
ties are distinguishable in all matter. The
retroactive and repellant forces of matter
were explained retroactive force as that
tendency in matter to unite with its kind
and when it predominates in any substance
that substance is 'solid if the repellant
force prevails, the Substance is in gaseous
form, While, when both forces are equally
distributed throughout the substance.
water is the result. AT this junction,
definitions of cohesion and adhesion were
given; cohesion as that force which holds
the particles of a body together, that is,
particles of like kind; adhesion as that
force which holds together particles that
formed illustrative of the force of cohesion.
Two leaden hemispheres, each weighing
sixteen ounces, were taken, their fiat sur
faces being placed together and pressed
tightly were made to cOhere; the process
OF welding iron was explained and the co
herence shown to be due to the cohesive
property of the particles of matter COM
posing the iron. The cohesion of liquids
was next referred to, and their tendency
form ho1
gether, into sphere, which constitutes a
perfect body-geometrica and physical
! calculations. For the purpose OF
demonstrating this tendendcy of liquids
to form spheroidal shape, several
experiments were performed, the first of
which was the mixing of Oil and water to-
gether, This was done by mixing with the
water some alcohol sufficient to establish
an equilibrity oetween,the density of the oil
and the water. A very impressive expert
ment was the mixture of the very heavy
| substance, salts OF zinc, and a very ligh,
substance known as iodine. This was also
| performed by equalizing the density of the
liquids as in the former experiment, except
that water was used instead of alcohol
The speaker then referred to the cohesion
| OF solids, known generally as crystallizatior
Of their compound form, of their definite
shape, the exactness of their angles, and o.
the tendency of inaninate matters to form
themselves by their inherent properties, il
perfect symmetry and order. Many speci
mems were distributed among the audienc,
showing conclusively the observance of tn,
law of order to high degree in the min
eral kingdom. One of them was piece O.
crystallized quartz in the center of which
was small piece of calcite all to itself an6
possessing all the peculiarities character
istic of calcite Another shown was a beau
tiful garnet upon whose surface was piec
of feltspar, which is very hard substauc,
and along side of it piece of mica, a rather
soft mineral, each of them possessing thel
own peculiarities and demonstrating to tn,
