SECRETARY’S REPORT 19 
Most of the accessions received in the division of electricity are 
in the field of electronics. Deserving particular mention are the 
experimental electron tubes of Drs. Langmuir and Hull donated by 
the General Electric Research Laboratory. Union College gave ex- 
amples of early electronic equipment. Bowdoin College sent the 
core of an electromagnet made by Joseph Henry, while Williams Col- 
lege presented a very early cathode-ray tube. Maj. J. Vanderhoef 
(USMC, ret.) contributed an unusual example of a Vibroflex 
key and a number of Japanese electron tubes. Through the Hazel- 
tine Research Corp., Dr. Alan Hazeltine donated the original experi- 
mental model of the neutrodyne circuit. 
The division of mechanical and civil engineering received for its 
horological collection two notable clocks: one, an elaborate astronom- 
ical clock of 1764, made in South Tyrol, and the other, a 17th-century 
Dutch pendulum clock built by Johannes Tegelbergh of The Hague, 
_ presented by Mr. and Mrs. Dillard B. Laseter. 
The machinery collections obtained from the Worthington Corpo- 
ration Henry R. Worthington’s first double-acting, direct-acting 
steam pump, built in 1844. <A fine highly finished quadruple-expan- 
sion marine steam engine, built in 1906 by the Dodge Brothers, was 
received from the University of Michigan. The Boeing Airplane 
Co. sectioned for display purposes a small gas turbine, which was 
transferred to the Museum by the Department of the Navy. 
The most significant accession acquired in the division of medical 
sciences is the transparent manikin of a woman which shows by 
electronic devices, light, and sound the location of the major organs 
of the human body and explains their functions. This exhibit was 
obtained from the Deutsches Gesundheits Museum. A collection of 
gas-oxygen machines, inhalers, and hypodermic syringes was donated 
by W. Harry Archer, D.D.S., an authority on Horace Wells, pri- 
mary discoverer of anesthesia. Another outstanding acquisition is 
a group of unusually rare ceramic drug jars donated by the Bristol- 
Myers Co. The collection included a 13th-century Rhages (Persia) 
albarello and a 13th-century Rakka (Mesopotamia) albarello, as well 
as a 15th-century Hispano-Moresque majolica drug container and 
an early 16th-century Faenza (Italy) dragonspout ewer. 
The division of physical sciences acquired specimens to fill the 
gaps in its collection of scientific instruments. Among these is a set 
of apparatus for demonstrating the mechanical powers presented by 
Middlebury College, a fine vacuum pump from Bowdoin College, an 
18th-century chemical furnace from Williams College, the famous 
set of tuning forks from the United States Military Academy, and a 
fine Oertling assay balance from Wheaton College. 
Outstanding accessions in the division of transportation are rare 
builders’ half-models, including an Eastern Shore of Maryland fish-
