 meteorites from Prof. H. A. Ward; a complete series of rocks and 

 minerals of the Cerro Mercado, Mexico, and a number of rare Mexican 

 minerals, in all aggregating 230 specimens, from Mr. W. H. Schlemm; 

 a series of remarkable sand concretions from California, from

 undum Company; seven specimens gold ores and tundra of Alaska, 

 from W. M. Johnston; and 31 specimens ores and minerals of Cali-

 exchange were obtained sections of five meteorites new to the collec- 

 tion. These were as follows: Felix and Persimmon Creek, from the 

 United States National Museum; Billings and Bella Roca, from Prof. 

 H. A. Ward; and St. Mesmin, from B. Sturtz. From the United 

 States National Museum were also obtained by exchange large pol- 

 ished slabs of orbicular diorite from Advance, North Carolina, and 

 of jasperized hematite from Ishpeming, Michigan. From the Mon- 

 tana School of Mines were received by exchange eleven specimens of 

 the ores and rocks of the Butte district; from Mr. R. F. Jones of 

 Concord, Massachusetts, a series of nine remarkable crystallized 

 specimens of datolite from Westfield, Massachusetts; from Prof. 

 L. H. Borgstrom, a cast of one of the Shelburne meteorites; and 

 from Mr. Henry E. Purdy of Michigan City, Indiana, two complete 

 fulgurites, each about 18 inches in length, and a number of fragments 

 of fulgurites. The most important purchase was that of the mineral 

 collection of Maynard Bixby of Salt Lake City. This collection 

 represents the fruits of many years' collecting by Mr. Bixby, chiefly 

 in the little known and comparatively inaccessible districts of Utah, 

 Colorado- and adjoining states of the West.' The collection is, there- 

 fore, largely made up of mineral occurrences little known elsewhere, 

 and affords material of a rare character for purposes of study and 

 display. Suites of specimens which may be mentioned as of especial 

 interest and importance are the following: Crystallized gold, weigh- 

 ing 3 ounces, Breckenridge, Colorado; silver nugget, weighing 3 

 pounds. Globe, Arizona;, crystallized realgar and orpiment, Mercur; 

 Utah; cr3^stallized argentite and hessite, Colorado and Montana,
