occurrence hitherto lacking in the Museum collections. An important 

 series of books was also obtained with the collection in number about 

 three hundred. Especially important are works relating to fossil 

 sponges of which a very complete collection was obtained. Other 

 books obtanied with the collection were of special value in completing 

 sets of Geological Surveys previously possessed only in part. Among 

 other gifts of importance the following may be mentioned: A complete 

 series of ores and specimens representing various stages of concentra- 

 tion of the copper ores of Bingham Canyon, Utah, donated by the 

 Utah Copper Company; a large amethystine twin crystal of calcite from 

 Joplin, Missouri, presented by F. P. Graves; a section of the Shrews- 

 bury meteorite presented by F. Justice Grugan; three slabs of West- 

 field, Alassachusetts, verd antique of standard museum size presented 

 by the Westfield Marble and Sandstone Company; fifteen specimens of 

 sand-barite concretions presented by Prof. C. N. Gould; a series of gold 

 and silver ores of the Porcupine and Cobalt districts of Canada, pre- 

 sented by Thomas H. Rea; a large slab showing fossil brachiopods and 

 worm tubes in relief, presented by A. G. Becker; five specimens of 

 polished Smithsonite of gem quality from Mex ; e«rj4ir^sented by Charles 

 H. Beers; and a large map of Colorado ^^i^t^rfey^T^.^A. Dohmen. 

 By exchange with the British Museum represehirlfive sections of the 

 Eli Elwah and Uwet meteorites were obtained, and by exchange with 

 the University of Bristol, Bristol, England, 121 specimens represent-

 in Great Britain. From Rev. P. E. Nordgren 56 specimens of inver- 

 tebrate fossils representing 15 species of Carboniferous and Devonian 

 age from localities in Pennsylvania and New York, were also received 

 by exchange; from A. G. Becker, 82 specimens representing 15 species of 

 Devonian invertebrates; from H. G. Shelby, 12 specimens representing 



3 species of Iowa crinoids; and from Julius Bohm a fine specimen of the 

 hydrous beryllium borate hambergite from Madagascar, all by exchange. 

 The most important purchase was that of the entire mass of the 

 Ahumada, Mexico, meteorite. This is a pallasite weighing 116 pounds 

 and is the only meteorite of this group which has as yet been found in 

 Mexico. An exceptionally fine skull of the Tertiary carnivore Hyaeno- 

 don, two specimens of gold of unusual beauty and two relief maps, one 

 of the Malaspina Glacier region, Alaska, and one of the State of Illinois, 

 were also purchased. The Malaspina Glacier map is about 7 feet by 



4 feet 6 inches in dimensions and has the vertical and horizontal scales

 able glaciers extending down the valley to the ocean and bays. Of these
