UNIVERSITY CONTROL1
Advantages of the American Plan

Suggestions Looking to Reform

PROFESSOR J. J. STEVENSON
AMPLE justification for further consideration of problems connected with university control exists in the vastness of the interests concerned. The commissioner of education, in his last report, states that in the United States there are 607 colleges and universities, with almost 22,000 instructors and approximately 118,000 students; with property, real and personal, valued at $465,000,000 and an income in 1904 of $40,000,000.

M. H. POINCARÉ
IN the articles I have heretofore devoted to space I have above all emphasized the problems raised by non-Euclidean geometry, while leaving almost completely aside other questions more difficult of approach, such as those which pertain to the number of dimensions.

PROFESSOR GARY N. CALKINS
AT the present time the importance of protozoa-study is recognized in all branches of biological science where, as single-celled organisms, they illustrate the manifold principles of living things. Thus it is in physiology, in cellular biology, in psychology and in general biology.

THE MAKING OF THE GRAND CAÑON OF THE COLORADO

[no value]
PROFESSOR A. R. CROOK
THE Grand Cañon of the Colorado furnishes the most impressive illustration of cañon-making forces to be found, and presents a fascinating chapter of world history. Nearly every visitor to the Cañon attempts an explanation of the manner of its making, and their explanations may be broadly grouped under five types—the explanation of the Indians who for centuries have inhabited the Colorado River region, that of one of the oldest white settlers in Arizona, that of a successful Chicago business man, that of a famous literary man, and finally that of men who have studied various phases of world making long enough to have learned the chief principles involved.

FRED DE LAND
THE desire to transmit speech over long distances probably dates back to the first wide separation of loved and beloved. That many methods have been suggested for the transmission of speech is of record. That speech has been mechanically or acoustically transmitted over many hundred feet of taut string and practically straight wires, during several hundred years, is true.

Mixed Marriages.

DR. MAURICE FISHBERG
ONE of the most important causes of the low birth rate of the Jews is their low marriage rate. Only about fifty years ago an unmarried Jew was very rare in Europe, while an old maid was hardly to be met with in the Ghetto. They then followed closely the rabbinical ordinances: “It is the duty of every Israelite to marry as early in life as possible.

PERCY F. BICKNELL
"I FIND it hard to say why I dislike John Stuart Mill," writes Lowell to Leslie Stephen, "but I have an instinct that he has done lots of harm." "For the sake of the House of Commons at large,” says Gladstone in a letter to Mr. W. L. Courtney, Mill’s biographer, “I rejoiced in his advent, and deplored his disappearance.

ROBERT DEC. WARD
Popular Belief in Climatic Change.—Belief in a change in the climate of one’s place of residence, within a few generations, and even within the memory of living men, is widespread. It is confined to no special region or people. It finds support among the most intelligent as well as among the uneducated.

THE AFRICAN PYGMIES

S. P. VERNER
THE presence of a group of the African pygmies at the World’s Fair at St. Louis attracted considerable attention to these little people. It has also revealed a number of erroneous popular conceptions with reference to them. The word pygmy, of course, comes from the Greek, being derived from the word denoting a unit of measure, the ell.

IT is not often that a scientific man can take part in the celebration of the fiftieth anniversary of a great discovery that he has made. Perkin, when he was a boy of eighteen, noted a muddy precipitate which occurred in connection with an attempt to produce quinine artificially.
