PROFESSOR BASHFORD DEAN
ASIA, whatever its contributions to art and science, has, humanely speaking, taught little to the west as to either the means of forming its illustrative collections or the manner of displaying them; in fact, as far as I am aware, the trend of Asiatic culture has been rather to deter its people from collecting.

PROFESSOR ARTHUR O. LOVEJOY
THE recent celebrations of the bicentenary of Linnæus’s birth had one sort of appropriateness in somewhat higher degree than is usual in such commemorations: they helped pay the debt of posterity to one of the great figures of the history of science in the currency that he had especially valued.

CHARLES SEDGWICK MINOT
Ladies and Gentlemen: I have referred in these lectures repeatedly to the cell and its two component parts, the nucleus and the protoplasm. To-night I shall have only a few references to make directly to these, and shall pass on for the latter part of the hour to another class of considerations bearing upon the problem of age.

W. W. STRONG
DURING the latter part of the nineteenth century a great deal of work was done upon electrical discharges in rarefied gases. In 1895 Röntgen made the epoch-making discovery that such a discharge was the source of very penetrating radiations.

PROFESSOR RUSSELL H. CHITTENDEN
EXPERIMENTAL study of the physiological needs of the body for food has indicated that the real requirements of the system, especially for proteid foods, are far below the amounts called for by existing dietary standards, and still farther below the customary habits of the majority of mankind.

PROFESSOR EDWARD S. MORSE
JEAN LOUIS RUDOLPHE AGASSIZ was born in Motier, Switzerland, May 28, 1807, and died in Cambridge, December 14, 1873. He was one of the great naturalists of the world, a student of Cuvier, beloved by Humboldt, counting every distinguished name in science as an admirer and idolized by his associates.

THE ORIGIN OF SLAVERY AMONG ANTS

DR. WILLIAM MORTON WHEELER
THE researches of the past few years have materially changed our views on the significance and phylogenetic origin of the so-called slave-making instincts among ants. And although the subject still involves many unsolved problems, we are now in a position to look back on its history and marvel at our too implicit confidence in certain analogies, at our neglect of the basic principles of phylogenetics, and at the inept questions we so long persisted in asking.

A TRIP AROUND ICELAND.

L. P. GRATACAP
REYKJAVIK was reached; the capital of Iceland, that first old landfall for the anxious vikings, who found that when they threw over their Lares and Penates those undiscerning deities floated ashore upon this inauspicious coast. The choice has a certain pictorial value, but for commercial purposes those old gods should have exercised more discretion, and commercial interests are beginning to weigh overpoweringly in this arctic metropolis.

THE extraordinary rise in prices which has occurred in the course of the past ten years—amounting to about fifty per cent. according to the index numbers of the Economist—is a serious matter for those who are dependent on fixed salaries, as is the case with most scientific men.
