KEPORT OF NATIONAL MUSEUM, 1919. 21 



archeolog}'; costumes, ornaments, and implements collected for the 

 Museum in Celebes by Mr. H. C. Raven under the auspices of Dr. 

 William L. Abbott; skeletal material from the ancient pueblo region, 

 presented by the Museum of the American Indian through Mr. F. W. 

 Hodge ; ancl crania and other physical remains from Alaska, the gift 

 of Dr. Edwin Kirk. 



The large increase this year in the department of biology was 

 chiefly due to the incorporation of the unrivaled collection of Antil- 

 lean land moUusks of approximately 400,000 specimens, donated by 

 Mr. John B. Henderson, a Regent of the Smithsonian Institution. 

 Other important biological accessions included the final installment 

 of Mr. Raven's Celebes collections, resulting from Doctor Abbott's 

 generosity ; a large amount of interesting material from the Collins- 

 Gamer Expedition to the French Congo, and several much desired 

 large mammals collected by Secretary Walcott during his explora- 

 tions in British Columbia. 



Among the additions to the National Herbarium should be men- 

 tioned a donation, chiefly Mexican, from Brother G. Arsene, repre- 

 senting the result of eight years' botanical collecting by himself and 

 associates among the Christian Brothers ; two large series of Philip- 

 pine plants, one received in exchange from the Bureau of Science, 

 Manila, the other acquired by purchase; two collections of Vene- 

 zuelan plants, the first the gift of Dr. H. Pittier, and the other an ex- 

 change from the Museu Goeldi in Para, Brazil; the Museum's share 

 of specimens from the Ecuadorean Andes collected by Dr. J. N. 

 Rose on an expedition undertaken jointly with the New York 

 Botanical Garden and the Gray Herbarium, and exchanges with the 

 last-mentioned institution added still other South American plants. 



In the department of geology the somewhat fewer additions this 

 year than last was in part compensated for by the unusual value of 

 sundry individual specimens. Among these may be mentioned exam- 

 ples of tungsten minerals both from domestic and foreign sources, 

 including a magnificent specimen of scheelite presented by Dr. J. 

 Morgan Clements, of New York City, and upward of 16.5 kilograms 

 of the extraordinary meteorite which fell at Cumberland Falls, in 

 Whitley County, Kentucky, on the 9th of April, 1919. 



The availability of the Frances Lea Chamberlain Fund enabled 

 the department to begin once more a systematic building up of the 

 Isaac Lea gem collection, a 7-gram kunzite, a 16-gram black opal 

 from Nevada, and 5 beautiful examples of Australian opals of a 

 variety heretofore unrepresented in the collections being among the 

 more important additions. 



The Middle Cambrian collections obtained by Secretary Walcott 

 from Burgess Pass in British Columbia, numbering nearly 7,000 in-
