Washington. Owing to its fragile nature and the probability that it 

 might not remain long in the present Museum building, it was decided 

 not to remount the specimen at this time, and it has not, therefore, been 

 placed on exhibition. A valuable collection of minerals, with some fos- 

 sils, the whole numbering about 300 specimens, was received from Miss 

 E. Curtiss. Many of these specimens were of exceptional beauty and 

 rarity. A somewhat similar, though smaller, collection ntimbering 48 

 specimens was received from Harold Wegg. It was chiefly valuable 

 for its series of Mazon Creek fossils. Two large specimens of fossil 

 logs, collected by Prof. R. D. Salisbury on his recent trip to Patagonia, 

 were received during the year and made an appreciated addition. From 

 Mr. Charles Winston eight exceptionally fine specimens of Carbonifer- 

 ous plants from Pennsylvania and Rhode Island were received. Some 

 of these were of importance as having been cotypes of Lesquereux and 

 all are large and well-preserved specimens. Two excellent specimens 

 of fossil glass sponge, Hydnoceras bathense, in group form were gener- 

 ously presented by the New York State Museimi. An excellent speci- 

 men of fossil fish from Wyoming was presented by Mrs. E. F. Goodall. 

 The skull of a Bison, found in an excavation near 67th Street, Chicago, 

 was presented by Thomas Farley. This is one of few occurrences known 

 showing the distribution of the buffalo in this vicinity. D. S. Renne, 

 Verona, Illinois, presented two large specimens of septaria, which are 

 interesting specimens of this type. From the Dolese & Shepard Com- 

 pany were received two excellent specimens of Orthoceras found near 

 Chicago. Besides the above a number of specimens of economic 

 interest were received through the kindness of donors. Among 

 these may be mentioned six specimens of gold and silver ore from 

 San Bernardino County, California, presented by Dr. T. A. Dumont; 

 27 examples of minerals and ores from Montana, presented by 

 Mr. J. E. Strawn; 15 specimens of gold ore from the Bella Mafiafia 

 Mine, Tlatlaya, Mexico, from William Brockway; 10 specimens illus- 

 trating the manufacture of ttmgsten lamps, from the General Electric 

 Company; two specimens of platinum and gold ore from the Boss Gold 

 Mining Company of Nevada; three specimens of vanadium ore from 

 the American Vanadium Company; 46 specimens of asphalt and its 

 products and two large photographs of Trinidad Lake, from the Bar- 

 ber Asphalt Company, and 1 1 specimens of coal tar and its products 

 from the Barrett Manufacturing Company. Dr. F. C. Nicholas pre- 

 sented a series of instructive specimens, which represented ores and 

 lavas of Sonora, Mexico, and Messrs. L. V. Kenkel and H. V. Guild 

 about 150 specimens of fossils and minerals from Idaho. In response to 

 a number of requests sent to producers of building stones and marbles,
