18 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1954 



less fish from the Upper Silurian of Norway and Spitsbergen, ob- 

 tained from the National Museum of Norway. The Ohio Geological 

 Survey, through John H. Melvin, presented to the collections the skull 

 and partial skeleton of a rare embolomerous amphibian from the 

 Pennsylvanian rocks of Ohio. An important purchase through the 

 Walcott bequest included the type specimen of the titanothere from 

 the Eocene Lisbon formation of Mississippi and the skull and jaws 

 of the archeocete whale Zygorhiza kochii from the Upper Eocene 

 Jackson formation of Mississippi. These were deposited on loan to 

 the Museum for study several years ago and are significant in that 

 the titanothere furnishes the only direct means of an age correlation 

 between the marine Gulf coast Eocene and the continental Eocene de- 

 posits of the Kocky Mountain region. This archeocete skull has fur- 

 nished the first conclusive evidence of the replacement sequence of 

 deciduous teeth by the permanent series in the order of whales.

 his design was presented by J. W. Jones, inventor. A schematic 

 model of a gas-turbine, electric-generating plant was donated by the

 continued to add to the collection of scrapbook data on watercraft

A wool-carding machine constructed from memory in 1793 by John

 formerly in use in Puerto Rico.

 279 woods of Fiji collected by Dr. A. C. Smith, 124 woods of Japan, 

 Thailand, Australia, and the Hong Kong market presented by Col. 

 Harold B. Donaldson, and 72 woods of Yucatan, the Marshall Islands,

 tory of the Department of Agriculture. 



The Museum acquired by purchase through the Dahlgreen fund a 

 series of 17 chiaroscuro woodcuts by John Baptist Jackson, repre- 

 senting the first attempt to reproduce paintings in the block print 

 medium. Thirteen woodcuts, dealing with views of Jerusalem and 

 environs, native types, and subjects from the Old Testament by con- 

 temporary Israeli artists, were presented by local donors. 



Sir Alexander Fleming, the discoverer of penicillin, presented a 

 specimen of the mold PeniciUitim notatum, and the Sir William Dunn
