SECRETARY'S REPORT 19 



Dr. Stuart H. Perry donated five meteorites. Of these, three from 

 the following localities are new to the Museum collections : Dayton, 

 Ohio; Loreta, Baja California; and Keen Mountain, Va. 



A rare Japanese rock, miharaite, was received in exchange from the 

 National Science Museum, Tokyo, Japan. 



Important accessions were received as gifts, exchanges, or transfers 

 by the division of invertebrate paleontology and paleobotany, includ- 

 ing 75 type specimens of Foraminifera from Trinidad from Dr. P. 

 Bronnimann ; the types of 14 Cretaceous Foraminifera and 39 Paleo- 

 cene Radiolaria from Dr. D. L. Frizzell ; 58 type Foraminifera from 

 the Lower Cretaceous of Algeria from Dr. A. ten Dam; 51 types of 

 Devonian ostracods from Iowa from Lee B. Gibson ; and 90 types of 

 Mississippian crinoicls from Dr. L. R. Laudon. 



During the year 288 crinoids, including a number of types, were 

 purchased under the Springer fund from Harrell L. Strimple. Income 

 from the Walcott fund provided funds for paleontological field work 

 which resulted in considerable collections from Alabama, Ohio, Penn- 

 sylvania, southern Appalachians, Tennessee, Texas, and Virginia. 



Transfers from the United States Geological Survey include 1,800 

 types of Ozarkian and Canadian cephalopods described by A. K. 

 Miller, Dr. E. O. Ulrich, and others; and 2 additional large lots of 

 types of cephalopods. The Office of Naval Research transferred 

 approximately 250,000 fresh-water Mesozoic and Cenozoic mollusks 

 collected by Dr. T. C. Yen. 



By exchange the Museum acquired Foraminifera from Algeria, 

 Aruba Island, Estonia, Gotland, Germany, Austria, and Japan, as well 

 as invertebrate fossils from Germany, Holland, Sicily, Australia, 

 Tasmania, and Canada. 



A representative collection of Oligocene and Miocene mammals from 

 the Canyon Ferry Reservoir area in Montana, a Cretaceous mosasaur 

 from South Dakota, and a Paleocene pantolambdid from North Da- 

 kota were included in the collections obtained by Dr. T. E. White and 

 transferred by the River Basin Surveys. Significant collections trans- 

 ferred by the United States Geological Survey included fish remains 

 from the Parana Basin of Brazil, mastodont and other remains from 

 the Ringold formation in Washington, and a variety of fossils from 

 Eocene and Oligocene localities in Wyoming and Montana. Paleon- 

 tological field work by Dr. C. L. Gazin under the Walcott fund 

 resulted in the collection of nearly 270 small mammals in several lower 

 Eocene and lower Oligocene deposits of western Wyoming. 



Engineering and industries. — Two examples of labor-saving ma- 

 chines that served the farmer during the nineteenth century were 

 received as gifts. One of these, a crank-operated fanning mill for 

 separating chaff from grain and hulls from beans, which was used in
