life-sustaining fluids to the organs of the body), the Sewell heart pump
(1950) to control delivery of air pressure and suction to the pumping
mechanism, and a large and valuable collection of dental equipment
formerly at the universities of Pennsylvania and Illinois. Dr. Blake
wrote the explanatory material and supervised the design and production
of the majority of exhibits in the renovated hall of medical and dental
history. He also contributed several scholarly articles and a book (see
bibliography) on the history of the healing arts and public health in
particular. He resigned on September 2, 1961, to join the staff of the
National Library of Medicine as chief of the History of Medicine
Division, and was succeeded by the author as curator of the Division.
From the summer of 1962 to April 1964, the Division benefited from the
expert advice of Dr. Alfred R. Henderson as consultant in the
preparation and designing of the surgical and medical exhibits of the
Museum of History and Technology.

During the period from 1961 to May 1964, the Division's collections
expanded greatly through its medical, dental, and pharmaceutical
acquisitions. Specimens of antiques acquired from 1961 through 1963
numbered up to 1,539 and included gifts from leading institutions and
individual philanthropists. The scope of these gifts and acquisitions
ranges from electronic resuscitators, microscopes, x-ray equipment, and
spectacles, to patent medicines, amulets, apothecary tools, dental
instruments, and office material of practitioners.

In the last decade, the interest in the national endeavor for promoting
research and scholarship in the history of medicine has increased
greatly. It was most appropriate, therefore, for the Smithsonian
Institution to play host on May 2 for two sessions of the 37th annual
meeting of the American Association for the History of Medicine held in
the Washington, D.C., area from April 30 through May 2, 1964. In
welcoming the members to the morning session in the auditorium of the
new Museum of History and Technology, Frank A. Taylor, director of the
United States National Museum, expressed the feeling that the meeting of
the Associati
