and with other government geological collections, previously 

 secured, furnished rich material for representing the geologi- 

 cal features of the country. The Thomas Barnett set of 

 Niagara fossils and minerals was also received in this year. 



Various private collections were received in 1856, the prin- 

 cipal ones being contributed by Doctor Ferdinand V. Hayden ; 

 I. Lippmann of Saxony; the Koenigliche Leopoldina Carolina 

 Akademie of Breslau, Prussia, and the Natiirforschende Ge-

In 1868 and 1871 important accessions were made to the 

 invertebrate department. William H. Dall sent part of the 

 collection made by him in Alaska, the Aleutian Islands, and 

 Eastern Siberia in i865-'6y, and other specialists contributed 

 Permian material from Kansas and Lower Silurian fossils 

 from Ohio. In 1875 the collections of fossil vertebrata from 

 New Mexico, obtained by Edward D. Cope, Paleontologist 

 of the United States Geographical Survey West of the looth 

 Meridian, were sent to the Museum. These collections form 

 the basis of the report by Professor Cope contained in the 

 fourth volume of the Reports of the above survey under 

 Lieutenant George M. Wheeler, of the United States Engi- 

 neers. The collections were from three horizons, and included 

 one hundred and six species, of which eighty-one were new. 



During 1878, 1879, and 1880, the following valuable dona- 

 tions were received: Black Hills fossils, from Professor Henry 

 Newton ; Californian fossils, from Senator Sargent ; and the 

 large collection of invertebrate fossils made by Lieutenant 

 Wheeler, presented by B. H. Lyon and other paleontologists. 



In 1884 the most important accession was that of Devonian 

 and carboniferous fossils from the United States Geological 

 Survey, many of them types of new species. Collections 

 were also received of Mesozoic and Cenozoic fossils from 

 California, Oregon, New Jersey, Florida, Alabama, and Mis-
