REPORT OF THE SECRETARY 13 



gathering of species from many parts of the world; a collection of 

 Crustacea brought together by the late Charles C. Nutting and pre- 

 sented by the State University of Iowa; an excellent series of Crus- 

 tacea from the 1934 Hancock Galapagos expedition; a large number of 

 specimens from Baffin Land from Captain Bartlett, who also sent 420 

 mollusks. Other mollusks received included over 1,500, chiefly North 

 American, from Mrs. H. F. Wickham, 1,680 from the Hawaiian Islands 

 from J. C. Bridwell, 500 from west Florida from G. S. Barnes, and 

 about 2,100 from Panama from Dr. James Zetek. From the Zoo- 

 logical Museum at Copenhagen came 221 crinoids, being part of a 

 collection made by Dr. Th. Mortensen in the East Indies and western 

 Pacific. Other important echinoderms came from the Bay of Bengal, 

 Arabian Sea, China Sea, and Sea of Okhotsk. 



In the National Herbarium additions totaled nearly 39,000 plant 

 specimens, particularly from Guatemala, Peru, Mexico, Argentina, 

 the Hawaiian Islands, Brazil, Yucatan, China, Labrador, Poland, 

 Colombia, French Indo-Cliina, and various parts of the United States. 



Geology. — Through the income of the Roebling fund there were 

 added 955 minerals, 16 gems, and 28 meteorites (13 new to the 

 Museum). Of these, the most important accession was the Tellef 

 Dahll collection, largely of minerals from the pegmatites of southern 

 Norway gathered before 1872. The outstanding specimen of this 

 lot is a iK-pound prismatic crystal of thorite. The Canfield collec- 

 tion was enhanced by a series of diamond crystals from the Belgian 

 Congo, and valuable specimens of ruby spinel, sapphire, tourmaline, 

 and garnet from Ceylon, Brazil, and Madagascar were added to the 

 Isaac Lea collection through the Chamberlain fund. The American 

 Gem & Pearl Co. donated an unusually large and brilliant garnet and 

 a small brown beryl from North Carolina. President Roosevelt 

 deposited in the Museum 38 specimens of marbles cut into various 

 ornamental forms. 



The petrological series received its most important accession in 

 years — the collection of rocks assembled by the late Dr. Henry S. 

 Washington, one of the world's leading petrologists, consisting of 

 about 2,500 specimens, which have formed the basis of many of the 

 donor's published researches. 



The paleontological collections were greatly enhanced by the addi- 

 tion of excellent fossil echinoids and starfishes from Iowa; brachiopods 

 from New Zealand, Spain, Russia, India, and United States; 3,200 

 fossil insects from the H. F. Wickham collection; 10,000 Paleozoic 

 and Cretaceous invertebrate fossils collected and presented by Dr. 

 G. A. Cooper, H. D. Miser, and R. D. Mesler; a large number of 

 Tertiary mollusks from Mexico ; and miscellaneous mammal and bird 

 remains from various localities.
