as seen at Copete, Mexico, presented by Francis C. Nicholas, was of 

 much interest, as was also a series of 10 specimens illustrating the con- 

 centration of iron ores by washing, presented by the Oliver Mining 

 Company. The Joseph Dixon Crucible Company presented an interest- 

 ing series of 24 specimens illustrating uses of graphite, and the H. W. 

 Johns-Manville Company 19 specimens illustrating the uses of asbestos. 

 The Heath & MiUigan Manufacturing Company presented 13 specimens 

 of buhrstones and pigments. A series of 10 specimens of lead and 

 silver ores from a new locality in California was presented by Dr. T. A. 

 Dumont, and a large specimen of allanite used as an ore of rare earths, 

 by A. C. Richards. A fine example of manufactured Monel metal was 

 presented by the Biddle Hardware Company. About 1,000 specimens 

 of varieties of agate and jasper from Oregon were presented by C. H. 

 Marsh, and a series of about 50 ores and minerals, chiefly from Mon- 

 tana and illustrating ores of historic interest, was received from J. L. 

 Rosenberger. Prof. R. D. Salisbury presented several specimens of 

 obsidian nodules from Patagonia and some diamondiferous sand from 

 Brazil, secured on his recent trip to South America. Through the kind- 

 ness of Prof. Salisbury also 225 specimens of copper ores and concentrates 

 were received from the Braden Copper Company, Rancagua, Chile. 

 This suite was very complete in representing all phases of occurrence 

 of the ore and many varieties of ore. By exchange with the University 

 of California a valuable accession was received in a skeleton of Canis 

 diurus, an extinct wolf from the asphalt beds near Los Angeles, Califor- 

 nia. By exchange with the United States National Museum a section 

 of the Perryville meteorite was obtained and one of the Nakhla meteorite 

 was obtained in a similar manner from the Egyptian Geological Survey. 

 Specimens of the Tepl and St. Germain meteorites were also obtained 

 by exchange, and some specimens of minerals, a trilobite, and a skull of 

 the fossil camel Stenomylus, the latter from Amherst College. The most 

 important purchase was that of the Davis Mountains, Texas, meteorite, 

 which was obtained entire. The entire mass of the Pickens County, 

 Georgia, meteorite was also purchased, a section of the St. Michel 

 meteorite and an unusual specimen of pollucite from Maine. 



The Department of Zoology received extensive accessions in all of 

 its several divisions. The most important accessions of the year were 

 those received from the Museum collectors in South America, which is 

 shown by the fact that they contained 38 new species and subspecies; 

 28 of birds and 10 of mammals. These have been described in Museum 

 publications and the types have materially added to the value of the 

 collections. In addition to these a very valuable collection of humming- 

 birds, numbering 591 specimens and representing about 386 species and
