22 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1941 



lots of Foraminifera came from such widely separated regions as 

 Mexico, Peru, New Zealand, and Arabia. Casts of 256 type specimens 

 of the fossil shell Turritella^ from the Tertiary rocks of the Pacific 

 coast, comprised an outstanding addition to the Cenozoic collections. 



As a result of paleontological field work in central Utah several 

 articulated Upper Cretaceous lizard skeletons (Polyglyphanodon) 

 and fragmentary mammalian jaws and teeth from the Paleocene 

 were received, in addition to 149 lots of vertebrate fossils collected 

 from the Bridger Eocene of southwestern Wyoming. Also worthy 

 of special mention among the new vertebrate material are the greater 

 part of the skeleton of the primitive mammal TJ intatherkum^ a partial 

 skeleton of a Palaeosyops^ and a perfect skull and jaws of the dog- 

 like Thinocyon velox. Parts of several fossil whales and porpoises, 

 from the Miocene Calvert formation of the Chesapeake Bay 

 country, were acquired. 



Engineering and industries. — To the section of transportation and 

 civil engineering came an operating exhibit of the Westinghouse 

 air brake, and three fine scale models, the Polish motorship Pilsudski, 

 the Rolls Eoyce automobile Silver Ghost, and the diesel-engined 

 trawler /Storm. 



A unique accession in the section of aeronautics, received as a 

 transfer from the Navy Department, was a fighter airplane known 

 as the Curtiss Sparrowhawk, a type developed in 1931-35 as an 

 auxiliary fighter to the dirigibles Alo^on and Macon. Several inter- 

 esting airplane models were received : The original model of a steam- 

 engined bombing helicopter designed in Civil War times and scale 

 models of the Columbia monoplane (1910), the triplane bomber 

 (1918), the U. S. Army pursuit tj'^pe P-35, the U. S. Army trainer 

 type BT-8, and the amphibian SEV-3N. 



In mechanical engineering the outstanding accession was an excep- 

 tional operating model made by Howell M. Winslow of a Reynolds- 

 Corliss steam engine of about 1900. The section of electrical 

 engineering and communication received three original Plante stor- 

 age battery plates and two replicas of the posted plate batteries 

 made by T. A. Willard in 1881 ; also the tone arm of a modern 

 photoelectric phonograph. 



One of the most spectacular acquisitions in recent years is the 

 93-dial display clock made by Louis Zimmer, of Lier, Belgium, for 

 the Brussels World's Fair in 1935. It is 14 feet high, tells the stand- 

 ard time of many places around the world, the tides in various 

 parts, and a great variety of calendar and astronomical events. The 

 section of woods and wood technology received the first letter file 

 made to handle correspondence unfolded and vertical. An important 

 and generous gift to the division of graphic arts was a collection
