THE PROCEEDINGS for the year 1882 are issued with a portrait of the late George Wansay Andrews, of Baltimore, who was the first First Vice-President of the American Pharmaceutical Association, elected to that office at the organization of the Association, in 1852, and who, in 1856, when the Association met for the first time in his native city, was called to the presidential chair. Mr. Andrews took a deep interest in the advancement of pharmacy and of science in general. He had been associated in membership with the Maryland Academy of Sciences for nearly half a century, and with the Maryland College of Pharmacy from the first inception, serving as its President for a number of years. He died in 1877, at the age of seventy-six years. A brief biographical sketch of Mr. Andrews will be found on page 861 of the Proceedings for 1878. Most of the wood-cuts used in this volume were loaned by the publishers of "New Remedies," "American Journal of Pharmacy," "Pharmacist," "Druggists' Circular," and "Oil and Drug News," and one was furnished by Professor Lloyd.
