CHARLES ALMA BYERS
THROUGH temporarily losing control over the Imperial Valley irrigation system in southern California, there has been suggested the possibility of creating an immense inland sea. This sea would extend from Volcano Lake in Mexico to a point a few miles north of Indio, California, and would spread over an area of 1,700 square miles, with a maximum depth of 280 feet.

KONRAD MEIER
HYGIENE, as a science, traces the causes of disease to which mankind is exposed in every phase of life. Its practical value lies in the preventing of these causes, through the sanitation of our surroundings and the rational care of body and mind.

DR. MAURICE FISHBERG
THE bulk of the Jewish population in the orient and eastern Europe lives mostly in the oldest and most congested parts of cities amid squalid and unsanitary surroundings, where the mortality rates are, by general experience, known to be excessive.

ANTON HANDLIRSCH
TO the majority of mankind, who supposedly are inclined to look on the bright side of life, the sound of the word 'insects’ ever recalls the picture of a wide-awake boy with a green net and possibly with a botanical box of the same hue, but more vivid in color, chasing along after the variegated butterflies and beetles.

SPENCER TROTTER
WHEN Adam, or the cave man, began giving names to the things of the earth and the things of the sky, it was probably with a view to a better personal acquaintance with the objects and for a ready means of conjuring up their images to the mind. In the same spirit a learned professor later defined a system of classification as a series of pegs to hang ideas on.

PROFESSOR C. JUDSON HERRICK
COMPARATIVE psychology has arrived. We have had our Descartes and our psychic epiphenomenalists; and their descendants, the vital mechanicians, are still with us. And no Luther has arisen to shatter at a stroke their gods (of tin and other artificers’ materials) and proclaim the reformation of psychology in a single revolutionary coup.

M. H. POINCARÉ
THUS I know how to recognize the identity of two points, the point occupied by A at the instant a and the point occupied by B at the instant β, but only on one condition, namely, that I have not budged between the instants a and β. That does not suffice for our object.
