THE SHIFTING OF THE EARTH’S AXIS

DR. SIDNEY DEAN TOWNLEY
THE earth has two principal motions, one of revolution about the sun, the other of rotation upon an axis. The revolution about the sun is accomplished in 365¼ days at an average speed of nineteen miles per second, or thirty-three times the speed of the swiftest modern projectile.

DESERT SCENES IN ZACATECAS

PROFESSOR J. E. KIRKWOOD
ABOUT 400,000 square miles of desert lie south and west of the Rio Grande. Much of this vast area occupies the great tableland, bounded east and west by long mountain ranges and reaching southward several hundred miles, where it becomes broken by more fertile areas; all this being, in fact, a continuation of the great southwestern desert region of the United States which prevails from Texas to California.

ALFRED RUSSEL WALLACE
THE lecturer began by stating, that, although the theory of Darwinism is one of the most simple of comprehension in the whole range of science, there is none that is so widely and persistently misunderstood. This is the more remarkable, on account of its being founded upon common and universally admitted facts of nature, more or less familiar to all who take any interest in living things ; and this misunderstanding is not confined to the ignorant or unscientific, but prevails among the educated classes, and is even found among eminent students and professors of various departments of biology.

DR. MADISON BENTLEY
OUR chapter of Sigma Xi has recently invited to its membership some two score persons who have shown themselves to be possessed of such talents and aspirations as the society honors and rewards. Of these new members many have finished their preparatory studies, and are entering upon the independent work of science.

ASTRONOMICAL SUPERSTITIONS

[no value]
JOHN CANDEE DEAN
THE great majority of our superstitions had their birth in attempts to interpret natural phenomena from erroneous ideas which consist of fancies suggested by the imagination. In other words, most superstitions are attempted short cuts to explain phenomena while omitting natural causation.

GEOGRAPHIC INFLUENCES IN THE DEVELOPMENT OF OHIO

PROFESSOR FRANK CARNEY
OHIO leads the states in its clay products, and its workable clays are practically inexhaustible. Ohio leads also in the number of presidents furnished the union, with unimpaired prospects for the future. Both ratings are consequences of geographic causes, as will appear in later discussion.

DR. L. C. KARPINSKI
IS there a limitation placed upon our thought by the language which we use? Do the Germans take to philosophy more easily than other people because of some peculiarly philosophical bias of their language? These are speculative questions which can never be satisfactorily answered.

THE ARGUMENT FOR ORGANIC EVOLUTION BEFORE “THE ORIGIN OF SPECIES”

PROFESSOR ARTHUR O. LOVEJOY
IN this year of the Darwin centenary it is worth while to raise two questions which have, in the mass of literature elicited by the occasion, received less consideration than they merit. At what date can the evidence in favor of the theory of organic evolution—as distinct from the hypothesis of natural selection—be said to have been fairly complete:

THE two great advances of modern science, perhaps the two most notable human achievements, are the doctrine of organic evolution and the doctrine of the conservation of energy. All the world has this year heen celebrating the hundredth anniversary of Darwin’s birth.
