PROFESSOR K. RUTHERFORD
SINCE the initial discovery by Becquerel of the spontaneous emission of new types of radiation from uranium, our knowledge of the phenomena exhibited by uranium and the other radioactive bodies has grown with great and ever increasing rapidity, and a very large mass of experimental facts has now been accumulated.

FRANK WALDO
WHILE the new building plant of the Harvard Medical School is approaching completion it seems a fitting time to give a brief account of the work of the school and its equipment. Harvard was the second of the American colleges to establish a school of medicine.

PROFESSOR A. D. MEAD
NOTHER American naturalist of the generation and the type to which belonged Leidy, Cope, Baird, Goode and Hyatt has passed away, Alpheus Spring Packard, professor of zoology and geology at Brown University. His lineage of sturdy, scholarly men, his academic heritage from great naturalists and the freshness of natural history in America at the time he commenced his career are all perceptible in the sterling quality and the wide range of his life work.

PROFESSOR WM. E. RITTER
PROGRESS in science leads to ever greater, more multifarious minutiæ of knowledge, and at the same time to ever clearer revelation of the close and vital interdependence among the different sciences. This characteristic of progress tends inevitably, for the individual investigator, toward an unyielding paradox.

PROFESSOR T. H. MORGAN
IT is a point of some interest that at the present time those zoologists and botanists, who seem willing to transfer their allegiance from Darwin’s theory of natural selection to the theory of the survival of mutations, often insist that the two points of view differ, after all, only in degree and that selection is still the key note to the situation.

EDWARD S. HOLDEN
AN extant annotation dated February 26, 1616, which is undoubtedly genuine, declares that upon this day Galileo was summoned before Cardinal Bellarmine and in the presence of witnesses was warned of the error of the Copernican opinion taught by him, and was admonished henceforth not to hold, teach or defend it in any way whatsoever, verbally or in writing . . . which injunction the said Galileo promised to obey.

A. M. SANCHEZ
TOBACCO was introduced into the Philippines soon after the Spaniards took possession, seed being brought from Mexico by Spanish missionaries. For many years little or no effort was made to restrict or encourage its cultivation, until 1781, when the cultivation and sale of tobacco was declared a state monopoly.

LATE one night in August I boarded the staunch little steamer 'Queen City,' at Victoria, and steamed out upon the Strait of Juan de Fuca, and up the western coast of Vancouver Island. This remarkable body of water, fifteen miles wide and seventy miles long, is the common gateway for British and American vessels.

JESUP, president of the American Museum of Natural History, provided in 1897 means for a thorough ethnological exploration of the northern coast of North America and Asia from British Columbia to the Amur River. The expedition has resulted in valuable accessions to the American Museum and in important ethnological, archeological, linguistic and anthropometric studies, which are now in course of publication in twelve volumes under the editorship of Dr. Franz Boas, of the American Museum and Columbia University.

SENHOR MANUEL GARCIA celebrated his hundredth birthday on March 7 in excellent health. He gave the first performance of Italian opera in New York City in 1825, and was long celebrated as a teacher of singing. His important contribution to science was the invention of the laryngoscope fifty years ago.
