brought by the waves to the Coast. The piece presented by Mr. 

 Marsh weighs about twenty pounds. He also gave specimens of 

 agate, obsidian, etc., from Oregon. Mr. Louis V. Kenkel of Seattle, 

 Washington, presented 50 specimens of ores and minerals from impor- 

 tant and relatively inaccessible mining districts in Alaska, and thus 

 added completeness to the series of ores from that region. Several 

 collections received by gift or purchase contained material of value. 

 These included 224 specimens of fossils and 116 specimens of rocks and 

 minerals presented by Mr. Charles Winston of Chicago, a collection 

 of about 200 specimens of fossils, minerals, ores and one meteorite 

 presented by Dr. H. P. Woley of Chicago, 135 specimens of inverte- 

 brate fossils from Iowa presented by Mr. A. G. Becker of Clermont, 

 Iowa, and 236 specimens of fossils and minerals purchased from Mrs. 

 Josie Pratten. The last named collection contained many specimens 

 of historical interest, especially relating to early researches in the 

 geology of Illinois. They included a number of types or supplemen- 

 tary types. A valuable specimen of emerald in matrix was presented 

 by Mr. W. S. McCrea of Chicago. Mr. John H. Muir of China gave 

 an interesting series of rocks and minerals from the interior of Tibet. 

 These included minerals used in bread making. A series of alundum 

 and its products presented by the Norton Company of Worcester, 

 Massachusetts, makes a valued addition to the collection of abrasives. 

 By exchange, about 50 specimens of valuable mineral specimens rep- 

 resenting localities or species not hitherto possessed in the collection 

 were received from the Foote Mineral Company. By collection about 

 1,500 specimens of invertebrate fossils were added. These were ob- 

 tained by the Assistant Curator of Invertebrate Paleontology near 

 Clermont, Iowa, and Little Traverse Bay, Michigan. The accessions 

 in the Department of Zoology during the year were comparatively 

 unimportant and limited in number, except those obtained in the field 

 mentioned elsewhere. 



expeditions and field work. — The main field work of the Depart- 

 ment of Anthropology was that of the Joseph N. Field Expedition in 

 charge of Dr. A. B. Lewis. During the year nearly 100 cases of addi- 

 tional material have been received from Dr. Lewis who is now on his 

 fourth year of this Melanesian Expedition. After a somewhat extended 

 visit late last year to the New Hebrides, Dr. Lewis returned to Sydney 

 in January of this year, to re-equip preparatory to spending a year on 

 the south coast of New Guinea, the first part of the year being devoted 

 to British New Guinea, the second to Dutch New Guinea. Dr. Lewis 

 is now on his way home. It is not known at this time how many 

 specimens have been acquired as a result of this expedition, but they
