NEW PROOFS OF THE KINETIC THEORY OF MATTER AND THE ATOMIC THEORY OF ELECTRICITY
UNIVERSITY OF CHICAGO
PROFESSOR ROBERT ANDREWS MILLIKAN
IT is my purpose herein to review the history of two of our most fundamental physical theories and to present some very simple and easily intelligible experiments which demonstrate the correctness of these theories, though they are by no means the only experiments which lead to the same goal.
ANY account of modern university education in China must necessarily be prefaced by a brief outline of that ancient system of education which has exerted perhaps the most powerful single influence of any that have made themselves felt in the development of a civilization more ancient than any other that now survives.
TO be told that five thousand years ago the Southern Cross could have been seen by one standing where London stands to-day would certainly cause most people surprise. Nevertheless such was the fact. That celestial asterism to which persons who have not seen it look forward as to one of the revelations incident to voyages into the tropics and then, on beholding it, feel egregiously duped, needed then no far travel to disclose.
FOR many years periodicals which make a point of entertaining timeliness have printed articles concerning the police force of New York City. Very few of these have been flattering, although at times, especially when some novelty of legislation has been inaugurated, or a new and more or less distinguished chief of the department entered upon his duties, they have expressed a guarded hopefulness of better things.

VI. HOMOGAMY AND FERTILITY
VII. SIGNIFICANCE OF THE RESULTS
DR. J. ARTHUR HARRIS
"THE supreme misfortune is when theory outstrips performance," wrote Leonardo da Vinci. He gave us, as far as I remember, no illustration of his epigram, but one is at hand in the modern attitude towards the Darwinian principles of natural and sexual selection.
THE synonymous use of the terms price and cost, in their relation to the acquisition of things which may constitute a living, is responsible for a large factor of error in popular discussion and opinion concerning the so-called “ high cost of living.”
To the commonly accepted belief that water tends to flow down hill, a certain type of visionary would object that though such a statement might be true as an abstract principle, dissociated from the real world of human achievement, yet it is not true as a matter of actual economic fact because men have invented pumps and pipes which make water flow up hill.
I. ANTIQUITY TO 1800; THE EFFORTS OF ISOLATED INVESTIGATORS
PROFESSOR RICHARD M. PEARCE
THE phrase "Research in Medicine" will naturally arouse different thoughts and associations in the minds of different groups of men. The bacteriologist will be reminded of Pasteur, Koch, Behring and Flexner and the triumphs of bacteriology and serum-therapy; the surgeon, of Lister and antisepsis, of anesthesia, and of the X-ray; the physician of new means of cure and of diagnosis, of specific sera and vaccines, of the electrocardiograph, the polygraph and other complicated instruments of precision; and the average layman of a confused and confusing welter of catchwords and slogans for popular agitations vaguely associated with antitoxins, mosquitoes, good water supply, sewage disposal, lowered infant mortality and the modern treatment of tuberculosis.
THE CENTENARY OF THE ACADEMY OF NATURAL SCIENCES OF PHILADELPHIA
DEATHS AMONG AMERICAN MEN OF SCIENCE
THE Academy of Natural Sciences of Philadelphia celebrated on March 19, 20 and 21 the centenary of its foundation, the last day being the actual date of the anniversary. On the first day Dr. S. G. Dixon, the president of the academy, gave a historical address and Dr. Edward J. Nolan, the secretary, gave reminiscences of the fifty years of his official connection with the academy. Delegates to the number of 147 presented letters, credentials and congratulations from the scientific and educational institutions which they represented.
