PRESIDENT DAVID STARR JORDAN
MR. LUTHER BURBANK, of Santa Rosa, California, is doubtless the most skilful experimenter in the field of the formation of new forms of plant life by the process of crossing and selection. He is the creator of many of our most useful plant forms: roots, nuts, fruits, grains and grasses, as well as of many of our most beautiful flowers.

HENRY FAIRFIELD OSBORN
I CONGRATULATE myself that it has fallen to my lot to set forth some of the chief contemporary problems of paleontology, as well as to make an exposition of the prevailing methods of thought in this branch of biology. At the same time I regret that I can cover only one-half of the field, namely, that of the paleontology of the vertebrates.

DR. ALLAN MCLAUGHLIN
THE assimilation of hundreds of thousands of aliens every year undoubtedly produces social and political effects worthy of close study, which are overlooked by some and exaggerated by others. The subject of the illiteracy of immigrants brings us naturally to the question of illiteracy at home, and statistics show many remarkable things in this connection.

DR. EDWARD S. HOLDEN
When the position of a heavenly body changes with such extreme slowness as to leave astronomers undecided as to the change even, and still more as to the direction of the change, it is their custom to compare two observations made at a great interval of time.

RADIOACTIVITY AND MATTER.*

CLEMENS WINKLER
THE discovery of radioactivity has opened to physical and probably also to chemical research a field of extraordinary and peculiar promise. We seem to have a source of energy which flows spontaneusly for unlimited time without tangible indication of its source; effects of energy are exhibited which neither in essence nor in phenomena resemble those previously known; substances are presented which seem to be of an entirely new kind, though they resemble our oldest and best-known elements so closely as to make their distinction difficult.

THE RIGHT REV. THE LORD BISHOP OF HEREFORD
WE hear much more than formerly about the public schools being the best training-place for good citizenship. Therefore, say the critics, it is reasonable to inquire how far their educational system, their ideals, their traditions, their fashions and the pervading spirit of their life fit the mass of their pupils intellectually and otherwise for the duties of citizenship and for grappling in the right spirit with the problems that will confront them.

H. C. WOOD
UNDERLYING our civilization, and often very necessary to our daily life, are agencies unrecognized by the general mass of humanity. Among these is a little book known as the ‘ United States Pharmacopoeia.' It concerns most nearly the medical profession, but perhaps most vitally the general public.

PROFESSOR JOHN B. SMITH
WHEN, a few years ago, it began to be generally realized that mosquitoes besides being sources of annoyance, were also dangerous to life and health because of their relation to certain diseases, the question of whether or not control or even practical extermination was feasible began to be seriously considered.
