tively, was renamed the Department of Science and Technology
of the Museum of History and Technology. It was also the first time
since its establishment in 1881 that the Division had two curators, for
on July 1, 1957, Dr. John B. Blake joined the staff.

Bowen Company of Providence, Rhode Island (1889). With the discovery of
x-ray, it was used for making x-ray photographs until early in the 20th
century.]

As a result of these changes, the Division was subdivided into a Section
of Pharmaceutical History and Health and a Section of Medical and Dental
History. The former was planned to encompass the collections of _materia
medica_, pharmaceutical equipment, and all material related to the
history of pharmacy, toxicology, pharmacology, and biochemistry, as well
as the Hall of Health which was opened November 2, 1957, and which
emphasizes man's progressing knowledge of his body and the functions of
its major organs.[18] The latter Section was planned to include all that
belongs to the development of surgery, medicine, dentistry, and nursing,
especially in relation to hospitals.

In October 1957, the Division acquired a collection of rare, ceramic,
drug jars which included two, 13th-century, North Syrian and Persian,
albarello-shaped, majolica jars; a 15th-century, Hispano-Moresque drug
container; and a 16th-century, Italian faience, dragon-spout ewer.
During the following two years, Curator Griffenhagen periodically toured
museums and medical and pharmaceutical institutions in this country,
South America, and Europe gathering specimens and information for the
Division and for publication, respectively. However, on June 27, 1959,
he resigned his curatorship to join the staff of the American
Pharmaceutical Association in Washington, D.C. Dr. Blake became the
curator in charge of the Division and Mr. Griffenhagen was succeeded on
September 24, 1959, by the author of this paper as associate curator in
charge of the Section of Pharmaceutical History and Health.

Dr. Blake, as curator of the Section of Medical and Dental History,
acquired a large number of valuable and varied specimens for the
Division's collections. They included optometric refracting instruments,
an early 1920's General Electric, portable, x-ray machine, the Charles
