THE DEVELOPMENT OF THE THEORY OF ELECTROLYTIC DISSOCIATION.*

[no value]
PROFESSOR SVANTE ARRHENIUS
AT first sight nothing seems to be more evident than that everything has a beginning and an end, and that it is possible to divide everything. Nevertheless, the philosophers of antiquity, especially the Stoicist, concluded, on purely speculative grounds, that these opinions are not at all necessary.

CONSERVATION OF HUMAN ENERGY, PRESERVATION OF BEAUTY.

[no value]
DR. J. MADISON TAYLOR
THE paramount importance of retaining human beauty is a fact requiring so little demonstration as to simulate a fundamental truth. All historical records bear witness to this verity. Popular interest seems extraordinarily awakened in this direction of late years, and in particular the daily press teems with observations on the subject.

FRANK T. CARLTON
DURING the last century the productive powers of man were multiplied many times by the utilization of the energy of coal and water through the agency of steam and electricity. As a result the human race has been lifted from a condition of struggle for the necessities of life to a higher plane of material comfort.

FORREST SHREVE
WE seldom give a thought to the fact that plants need food. They lead such mute, motionless lives that it is difficult to believe that they have, like ourselves, a bread-and-butter problem staring them constantly in the face. We watch the geraniums and begonias of our window-garden grow and bloom with nothing to nourish them but a few handfuls of earth and a little water.

DR. ALLAN McLAUGHLIN
THE persecution of the Hebrew race finds no parallel in history. Other races have suffered at the hands of the conqueror, but these other persecutions are transient and intermittent compared with the persistent persecution to which the Jew has been subjected for centuries.

MORE MEN IN PUBLIC SCHOOLS.

RICHARD L. SANDWICH
AMONG the recent movements in education, none is more worthy of notice than the call for more men in public school work. The proportion of women teachers has grown steadily. Fifty years ago the men engaged in school work outnumbered the women ; the civil war reversed this, and the gap has widened every succeeding year.

A SECOND CENTURY CRITICISM OF VIRGIL’S ETNA.
ÆTNA.

DR. CHARLES R. EASTMAN
CHIEF amongst natural phenomena to impose upon the imagination and challenge the understanding of classic authors was vulcanism in its direct and associate manifestations. Speculations as to the causes of earthquakes have at least as remote an antiquity as Thales and Pythagoras, of the sixth century B. C., and the relation between volcanic activity and proximity to the sea was clearly perceived in the time of Aristotle.

THE EVOLUTION OF THE HUMAN HAND.

[no value]
[no value]
PROFESSOR ROBERT MAcDOUGALL
THE succession of organic modifications which resulted in the formation of the human hand is part of the general process of evolution by which in the animal series the means of progression and of the taking of food were shaped by the environmental conditions under which life was carried on.

PROFESSOR SIMON NEWCOMB
AMONG the numerous attractions of the Universal Exposition at St. Louis, there is one which appeals with special force to all interested in the progress of learning. The assembling of congresses on various subjects has, especially in recent years, been so prominent a feature of great expositions of industry that such gatherings have recently tended to lose in interest.
