The Department of Geology has been the recipient of an unusually 

 large number of accessions during the year, nearly all being gifts. 

 The continued interest of Mr. W. J. Chalmers has been evinced by 

 his gift of a fine series of moss agates from Montana showing remark- 

 able landscape effects, and the addition of sixteen specimens, a num- 

 ber of which are of high gem quality, to the crystal collection. These 

 specimens include crystals of beryl from Brazil, tourmaline from 

 Maine, tourmaline and kunzite from Madagascar, and quartz from 

 Japan. Another addition to the gem collection was received from 

 Ezra C. Knopf, who gave twenty-four specimens of rough and cut 

 catalinite which provide a good representation of this semi-precious 

 stone. A collection of over three thousand specimens of invertebrate 

 fossils, besides some minerals, was presented by Mr. J. C. Langtry. 

 This collection was gathered by the late C. B. Dyer, a well-known 

 paleontologist, and is particularly notable for the large variety of 

 specimens in it and the careful preparation of each. Besides repre- 

 sentatives of several hundred species, the collection contains two para- 

 types. The material constituting the collection was gathered chiefly in 

 Ohio, but other districts are represented. The collection includes a 

 number of beautifully preserved specimens of crinoids and trilobites 

 well adapted for exhibition, and all of the material is so well worked 

 out that it will lend itself readily to further study. A number of 

 specimens of minerals from localities now exhausted is another 

 valuable feature. A fine series of fossil plants, containing repre- 

 sentatives of nineteen species from Eocene beds of Louisiana and 

 Texas, was presented by Prof. O. M. Ball of the Agricultural and 

 Mechanical College of Texas. The excellent state of preservation 

 of these fossils and the care with which they had been prepared, 

 mounted and named by Prof. Ball gave especial value to the gift, 

 both for the purposes of exhibition and study. The Standard Oil 

 Company of Indiana kindly presented a collection of 168 specimens 

 illustrating uses of petroleum wax, which shows many interesting 

 and important substances derived from this product. This company 

 also provided a large floor case built according to the Museum standard
