THE BERMUDA ISLANDS AND THE BERMUDA BIOLOGICAL STATION FOR RESEARCH.

PROFESSOR EDWARD L. MARK
I FEEL a certain hesitancy in speaking on the subject I have selected to talk about—the Bermuda Islands—because of the number of prominent naturalists who have written so excellently about them. It should be stated at the outset that I do not aim to add to the stock of our knowledge about the Bermudas.

M. GASTON DARBOUX
TO appreciate the progress geometry has made during the century just ended, it is of advantage to cast a rapid glance over the state of mathematical science at the beginning of the nineteenth century. We know that, in the last period of his life, Lagrange, fatigued by the researches in analysis and mechanics, which assured him, however, an immortal glory, neglected mathematics for chemistry, which, according to him, was easy as algebra, for physics, for philosophic speculations.

SOME PRESENT PROBLEMS IN TECHNICAL CHEMISTRY.

PROFESSOR W. H. WALKER
TECHNICAL chemistry may be regarded as the performance of a chemical reaction or series of reactions on a scale sufficiently large and by a method sufficiently economical to enable the product to be sold at a profit. The problems which confront the investigators in this field of endeavor may, therefore, be divided into two classes according as they pertain to the chemical reaction involved, or to the process to be employed in carrying on this reaction.

ANALYSIS of vital statistics for the last three-quarters of a century shows an average increase in the duration of human life among civilized peoples from 42.2 years to 48.5 years. The chief increase has been during the latter half of that period, and, for the most part, by the reduced mortality from zymotic diseases, but, above all, from pulmonary tuberculosis, from which the reduction of mortality has been nearly fifty per cent.

THE NATURAL HISTORY OF ADOLESCENCE.

PROFESSOR JOSEPH JASTROW
THE history of philosophical thought itself participates in the scheme of evolutionary progress which it expounds and records. The sequence of culture changes and the soil of motives in which these find root remain the permanently vital sources by which to illustrate and to comprehend the nature of human endowment, striving and achievement.

A. LAPTHORN SMITH
EDUCATION on the continent of America, and more especially in the United States, has reached a point of perfection which hardly leaves room for any further development.* At first sight, this would seem to be a very satisfactory state of affairs and, to the ordinary observer, the question of still higher education would seem to be deserving of all praise.

LILLIAN CHAPIN
HYGIENE is the one secondary school subject that every pupil will find necessary throughout life. In few high schools, however, has it received the treatment a subject of such importance demands. This article is a plea for definite, forceful experiments and demonstrations in hygiene comparable with the experiments and demonstrations so long deemed essential in physics and chemistry.

IT is natural that the Carnegie Institution should claim frequent attention in a monthly report on the progress of science. Never before has there been an attempt on so large a scale to stimulate scientific research. The Royal Society of London; the Academies of Sciences of Paris, Berlin, Vienna, St. Petersburg and Rome; The Royal Institution of London, and the Smithsonian Institution, combined, do not have an income approaching that of the Carnegie Institution, nor have they the same freedom in the disposition of their funds.
