DR. J. ARTHUR HARRIS
BY organic evolution the broad-minded biologist of to-day understands merely the natural as opposed to the supernatural processes by which the hundreds of thousands of kinds of organisms which now inhabit or have inhabited the surface of the earth have come to possess the morphological and physiological peculiarities which distinguish them from each other.

PROFESSOR F. R. MARSHALL
UNTIL a few months ago Americans were inclined to express surprise at the paternalistic measures for fostering agriculture as adopted by other countries. Now, the necessity of ensuring adequate food supplies has made us willing to assume the same encouraging attitude toward agriculture as we have always held toward our manufacturing enterprises.

IS EUCLID’S GEOMETERY MERELY A THEOEY?

EDWARD MOFFAT WEYER
AS there are creeds in religion, so there are creeds in geometry. Most of us pin our faith upon Euclid, whose masterpiece of reasoning is still, after twenty-two centuries, the wonder of the world. The system that Euclid founded stands, as it were, four-square and solid ; it meets every need in the only kind of space that we practically know.

ALFRED SANG
SCIENCE originated in the temple; for ages it remained as a mass of detached observations floating in mysticism. The civilization of Greece gave us the broad lines of many of the sciences, but the confinement of knowledge to monasteries, the enslavement of the human mind and the suppression of the wisdom of the ancients during the dark middle ages, deferred the rise of science until within comparatively recent times.

THE RELATION OF THE MANUAL ARTS TO HEALTH

LEWIS M. TERMAN
THE relation of the manual arts to health may be considered under two aspects : as they affect the immediate well-being of the pupils and teachers concerned, or in their ultimate influence upon the individual and upon society. Under the former caption belong the hygienic rules pertaining to the performance of the manual occupations in the school, these mostly of negative and precautionary nature The latter relation has to do with the positive contribution which the manual arts are capable of making toward the final attainment of mental and physical health.

EDWARD S. HOLDEN
SOME popular writers on the Renaissance give, and seek to give, the impression that the sculpture known to the Renaissance was pure, high Greek, and that these masterpieces set all Italy astir. Scholars know better, but most of us are not scholars.

APART from the Christmas holidays, the month of April is the favorite season for scientific meetings. It would be the best time in the year, if it were only possible for educational institutions to agree on a week ’s holiday. At present some of them have a vacation at a regular time, some follow Easter and some have none.
