=Royal Society Medalists.=--The Copley medal was conferred, at the recent anniversary meeting of the Royal Society, upon Lord Rayleigh for his splendid service to physics, his investigations, the president said in presenting the award, having increased our knowledge in almost every department of physical science, covering the experimental as well as the mathematical parts of the subject. "His researches, from the range of subjects they cover, their abundance, and their importance, have rarely been paralleled in the history of physical science." A summary account of the principal ones was given in the sketch of him published in the twenty-fifth volume of the Popular Science Monthly (October, 1884). At the same meeting of the Royal Society the Royal medals were conferred upon Prof. G. F. Fitzgerald, for his brilliant contributions to physics, and Prof. William C. McIntosh, for his very important labors as a zoölogist. Professor Fitzgerald's investigations have been in the field of radiation and electrical theory, and in a manner complementary to those of J. Clerke Maxwell. Among his works is a memoir presenting a dynamic formulation of the electric theory of light on the basis of the principle of least action, which concludes with a remark upon the advantage of "emancipating our minds from the thraldom of a material ether." Professor McIntosh was spoken of as "one of a distinguished succession of monographers of the British fauna, who, beginning with Edward Forbes, have, during the last fifty years, done work highly creditable to British zoölogy." He is author of a great monograph of the British Annelids, which is still in progress of publication by the Royal Society, and of an important contribution to the Challenger reports, and was the founder of the first marine biological station in Great Britain--the Gatty Marine Laboratory at St. Andrews. The Davy medal was bestowed upon Edward Schunck for researches of very high importance in organic chemistry. These works include a remarkable series of contributions to the chemistry of the organic coloring matters, particularly those relating to the indigo plant and to the madder plant. Of late years he has studied, with distinguished success, the chemistry of chlorophyll.
