56 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1963 



Upper Triassic, the Upper Jurassic, and the Upper Cretaceous, and 

 the sea vertebrates of the Upper Cretaceous. Mr. Matternes com- 

 pleted the third mural painting, for the age of mammals hall, which 

 depicts terrestrial life during the Oligocene in North America. Speci- 

 fications were prepared for the fourth mural in the hall which will 

 represent animal assemblages in the Pliocene Epoch. 



Eight new exhibits to be displayed in the halls of medicine, den- 

 tistry, and pharmacy in the new Museum of History and Technology 

 were temporarily installed in the gallery of medical sciences in the 

 Arts and Industries Building; these include units on the develop- 

 ment of the microscope, medical and dental equipment, and crude 

 drugs. Exhibits planned or prepared to portray various phases of the 

 history of medicine include a diorama showing the performance of 

 an operation in about the year 1805, the corner of a ward in the Mas- 

 sachusetts General Hospital as it appeared in 1875, and a dental office 

 in Illinois during the period 1912-20. Most of the units have now been 

 designed and produced for these halls under the direction of Dr. Sami 

 K. Hamameh. 



Exhibits for the hall of tools, planned by curator Silvio A. Bedini 

 in cooperation with exhibits designer Harry Hart, neared completion 

 in the exhibits laboratory. Displays of the handtools of the black- 

 smith, cooper, wheelwright, pump log maker, and woodworking trades 

 were in the designing stage. In mid- June artist E. McGill Mackall 

 of Baltimore installed the first unit in the new hall of tools — a large 

 background painting showing skilled workmen fabricating marine 

 propellers. An exhibit of a mid-19th-century machine shop was 

 moved to the new building and will be erected early in the summer. 



The production of exhibits for the civil-engineering hall neared 

 completion with the construction of a series of wooden arches illustrat- 

 ing the American, Austrian, and English systems of tunnel timbering. 

 The Bethelhem Steel Co. fabricated especially for this hall a cast- 

 iron tunnel segment 10 feet in diameter, such as is used for lining 

 tunnels through soft soil. The technical direction of this hall is 

 the responsibility of associate curator Eobert M. Vogel, with exhibits 

 designers John Brown and Harry Hart providing the design of in- 

 dividual exhibits. 



In preparation for developing the exhibits in the future hall of elec- 

 tricity, associate curator Bernard Finn made a study of the electrical 

 exhibits in the museums of Europe. Substantial progress was made 

 in the design of exhibits in the first third of the hall, devoted to wired 

 communications and power. 



At the end of the year, the Pioneer locomotive of 1851 joined the 

 historic engines, coaches, and streetcars now assembled in the railroad 

 hall in the new Museum of History and Technology. These large,
