advancement and diffusion of science.
It is not possible in this note to give a statement even of the main features of the programs. The American Association meets in ten sections, each with its own presiding officers and its program of papers and discussions lasting several days. There are further about twenty national societies which meet in affiliation, sometimes holding joint sessions with the sections of the association or with one another and sometimes meeting separately. These societies, which include those devoted to astronomy, physics, mathematics, chemistry, geology, geography, zoology, entomology, bacteriology, physiology, anatomy, botany, psychology, philosophy and anthropology, each has its independent organization and officers, so it is obvious that the programs are extensive. There will be at least five hundred papers read, which when published in detail will fill more than ten thousand pages.
The high character and broad interest of the proceedings may be briefly but adequately shown by a list of some of the retiring or presiding officers, most of whom will make addresses. Every one familiar with science in America will understand that they represent the best work now being accomplished. These officers include: Professor W. H. Welch of the Johns Hopkins University, Professor C. M. Woodward of Washington University, Professor William James of Harvard University, Professor Charles B. Davenport of the Cold Spring Biological Laboratory, Professor E. C. Pickering of the Harvard College Observatory, Professor Carl Barus of Brown University, Professor W. F. Osgood of Harvard University, Dr. W. F. Hillebrand of the U. S. Geological Survey, Mr. C. C. Adams of New York City, Professor W. E. Castle of Harvard University, Mr. A. H.
