I TAKE for the subject of my address the science of astronomy, and propose to give a brief historical sketch of it, to consider its future development, and to speak of the influence of the sciences on civilization. The science of astronomy is so closely connected with the affairs of life, and is brought into use so continuously and in such a systematic manner, that most people never think of the long labor that has been necessary to bring this science to its present condition.
IN a former paper published in THE POPULAR SCIENCE MONTHLY* we considered the origin of sex in plants, describing the progenitors of the sexual elements or gametes and some of the conditions under which these cells assume sexual characters.
EXPERIMENT has already demonstrated the value of practical forestry as a sound business measure. The general application of conservative methods in the handling of public and private forest lands in this country is no longer a remote possibility.
THIS branch of Nassau for five generations from William the Elder (1487-1559) to William, Prince of Orange, who became king of England (1650-1702), includes in the direct line 30 names.

FROM the earliest times physicians have taken the lead in all that relates to the prevention of disease. In times of epidemic their advice is sought by afflicted communities and they have been instrumental in securing most of the legislation which has been enacted with a view to preventing or restricting the prevalence of infectious diseases.
THE accounts of great men in biographies and histories belong to literature rather than to science. Modern science is either genetic or quantitative. It seeks to discover those uniformities which we call causes and to use that method of description which we call measurement.
BESIDES the individual works named in recent numbers of THE POPULAR SCIENCE MONTHLY, the collected works, or dictionaries, of biography, particularly those treating specially of scientific men, contain valuable information of the lives and labors of the chemists.
