20 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1942 



Rose City, Mich., stony meteorite, weighing 2,690 grams, one of the 

 largest individuals of that fall, presented by Dr. Stuart H, Perry, 

 and a 184-pound mass of cassiterite from Goodwin Gulch, Stewart 

 Peninsula, Alaska, perhaps the largest single piece of this tin mineral 

 ever found. 



Outstanding among the accessions by the division of invertebrate 

 paleontology and paleobotany are a lot of more than 1,500 type speci- 

 mens of fossil invertebrates; 4 tons of limestone blocks containing 

 beautifully preserved silicified fossils obtained by Dr. G. A. Cooper 

 in the Permian formations of the Glass Mountains of Texas; and 

 8,000 invertebrate fossils obtained by Dr. C. E. Resser from the Cam- 

 brian and Devonian rocks of Montana, Utah, and the Canadian 

 Eockies. 



Engineering and Industries. — Scale models of historic aircraft 

 formed the largest group of important objects received by the division 

 of engineering. Among these are models of 10 winners of the Thomp- 

 son Trophy air races and a model of Sikorsky's 4-motor biplane, 

 Grand^ of 1913, which is called the first successful 4-motor airplane. A 

 timely addition to the division's extensive series of aircraft engines is 

 an example of the Allison liquid-cooled internal combustion engine, 

 type V-1710-C, which represents one of industr3^'s great contributions 

 to the present war. Another very timely accession is a 14-ton, 4- wheel- 

 drive reconnaissance and command automobile, or "jeep," lent by the 

 War Department. A transparent, plastic-body 1939 Pontiac automo- 

 bile, received as a loan, fills the division's need for a late-model car. 



With the consent of interested persons, the material contained in 

 boxes deposited in the care of the Smithsonian Institution by Alex- 

 ander Graham Bell in 1880 and 1881 was transferred to the division of 

 engineering. Included are several photophone transmitters, selenium 

 cell elements of receivers, an electrotype phonogram, and a grapho- 

 phone equipped with a reproducing element designed to reproduce 

 sound through the medium of a jet of air without mechanical contact 

 with the record. 



The most valuable object added to the medical exhibit was the first 

 Emerson iron lung, completed in 1931, and used for several years to 

 produce artificial respiration. 



The most noteworthy accession in graphic arts was the gift of 183 

 Currier and Ives prints previously loaned to the division of graphic 

 arts by Miss Adele S. Colgate. This accession was reported and de- 

 scribed briefly in the report for 1941. With the cooperation of the 

 Evening Star Newspaper Co. of Washington, the division's exhibit 

 showing the steps in the printing of a newspaper was entirely reno- 

 vated by the substitution of 23 new specimens to replace those now 

 obsolete.
