sources. Donated specimens and those received through exchange 

 comprised many valuable minerals from many parts of the world. 



The total number of distinct meteorite representatives in the col- 

 lection was increased from 592 to 606 during the year. The most 

 important accession to the petrological collection was a series of 

 anorthosites, interesting rock types, from Norv\-ay. 



In stratigraphic paleontology an important addition was about 

 100,000 specimens illustrating the Middle Devonian faunas of central 

 New York, collected by Dr. G. A. Cooper a number of years ago 

 and received in exchange from Colgate University. About 100,000 

 others, Middle Paleozoic rock specimens, came from Illinois, Indiana, 

 Iowa, and Michigan. 



Invertebrate fossils added represented Chile (Jurassic), Timor 

 (Permian). Portugal (Ordovician), Oklahoma (Carboniferous), 

 Florida (Miocene), and Hawaii (Pleistocene). The paleobotanical 

 collections were enriched by rare types of fossil cones from the Cre- 

 taceous of Maryland and the Eocene of North Dakota. 



Field expeditions in vertebrate paleontology yielded the following 

 rarities: From Wyoming a nearly complete articulated skeleton of 

 the mammal Coryphodon^ so far as known the second entire specimen 

 as yet found; from Montana articulated parts of the little-known 

 dinosaur Procheniosaurus^ fragments of Leptoceratops^ and an adult 

 skull of Brachyceratops. Tlicre were also added a nearly complete 

 skeleton of the edentate mammal Scelidodon capellini from South 

 America and the only known complete skull of the Oligocene lizard 

 Glyptosaurus giganteus. 



Arts and industries. — The outstanding accession in aeronautics was 

 the airplane Winnie Mae, flown by Wiley Post and Harold Gatty, and 

 subsequently by Post alone in various record flights, which was pur- 

 chased through funds provided by a special Congressional appropria- 

 tion. The airplane Polar Star, of exj^loration fame, used by Lincoln 

 Ellsworth in the first flight across Antarctica in November and De- 

 cember 1935, in an expedition sponsored by the National Geographic 

 Society, was received as a gift from Mr. Ellsworth. Propellers from 

 the airships Macon and Akron were transferred from the Navy De- 

 partment. The collection of scale models of aircraft was increased 

 by 14 specimens, including models of the following: The Short 

 Brothers' airplane of 1911 ; the Breg-uet sesquiplane Point dVnterro- 

 gation ; the first plane built by Glenn Martin in 1909 ; a V-F-7-H ; 

 and the Baby Clipper. 



In mechanical technology the most important accession was the 

 original locomotive Atlantic, built at Baltimore in 1832, and the first 

 locomotive to enter the National Capital. A Ford model T touring 

 car of 1913, given by Harvey C. Locke, proved the most popular
