tions or exchanged for specimens needed to complete collections in 

 the Museum, and 33,966 specimens were distributed as loans to spe- 

 cialists and students for study and identification. 



The accessions to the Museum collections in all its departments 

 are described in detail in the report of the assistant secretary, Ap- 

 pendix 1, and only a few of the outstanding gifts will be mentioned 

 here. In the department of anthropology, the ethnological collec- 

 tions were enriched by the addition of a unique series of objects illus- 

 trating the material culture of the Indians of eastern Panama, re- 

 sulting from the Marsh-Darien expedition, and by a collection of 

 California Indian baskets bequeathed by the late Miss Ella F. 

 Hubby, of Pasadena. In physical anthropology, a number of casts 

 of the remains of early man were received, including several of the 

 famous Trinil man of Java, Pithecanthropus erectus, from Dr. 

 Eugene Dubois, and also much valuable skeletal material. The de- 

 partment profited especially through explorations conducted by the 

 Bureau of American Ethnology, and by the National Geographic 

 Society under the direction of Mr. Neil M. Judd, which resulted in 

 valuable additions to the collections. 



The most notable gift to the department of biology was the collec- 

 tion of Coleoptera and mollusks bequeathed to the Museum by the 

 late Col. Thomas Lincoln Casey. The beetles alone in this collec- 

 tion are estimated at 90,000 specimens, representing 16,000 species. 

 A wonderful store of rich material also has been added to the depart- 

 ment in the large collections presented by the National Geographic 

 Society as the result of expeditions in China by Dr. J. F. Rock and 

 Mr. F. R. Wulsin, which include 4,500 specimens of vertebrates and 

 68,000 plants. Additional collections from China have also been 

 received from the Rev. D. C. Graham and Mr. A. de C. Sowerby. 



In the department of geology, the paleontological collections have 

 been the chief beneficiaries, having received the results of your secre- 

 tary's field work for the past four years, as well as collections made 

 by Doctor Bassler, Doctor Resser, and Doctor Ulrich. The other 

 divisions have all received valuable additions, including a number 

 of interesting minerals contributed by Col. W. A. Roebling, and a 

 crystal of the new mineral, afwillite, donated by Mr. Alpheus F. 

 Williams. One of the most interesting exhibits is a crystal ball of 

 unusual size and perfection, weighing 110 pounds and measuring 

 1314 inches in diameter, shown through the interest of Mr. Worces- 

 ter R. Warner and the courtesy of the Fukushima Co. (Inc.), New 

 York. This ball is said to be the largest of its kind in the world 

 and has attracted much attention from visitors. 



In the division of mechanical and mineral technology there was a 

 slight falling off in the number of accessions received, principally
