36 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1919. 



including a mule deer, Rocky Mountain goat, and Rocky Mountain 

 sheep, which made a valuable addition to our collections. 



Among the additions to the National Herbarium may be particu- 

 larly mentioned about 12,000 plants, chiefly from Mexico, donated by 

 Brother G. Arsene and representing the result of eight years' botani- 

 cal collecting by himself and associates among the Christian Brothers. 

 The collection of Philippine plants was greatly increased by the ad- 

 dition of two lots, aggregating more than 9,600 specimens, one 

 received in exchange from the Bureau of Science, Manila, the other 

 acquired by purchase. The South American series was also aug- 

 mented considerably by the donation of 1,761 Venezuelan plants by 

 Dr. H. Pittier and 1,077 specimens exchanged with the Museu Goeldi 

 in Para, Brazil, l)esides the Museum's share of about 2,000 specimens 

 from the Ecuadorean Andes collected by Dr. J. N. Rose on an 

 expedition undertaken jointly with the New York Botanical Gar- 

 den and the Gray Herbarium; while exchanges with the last-men- 

 tioned institution added approximately 1,450 more South American 

 plants. 



The exhibition collections were closed most of the year on account 

 of the space having been turned over to the Bureau of War Risk 

 Insurance. However, toward the end of the year the halls on the 

 first floor, containing mostly the mammals and birds, including the 

 great biological groups, were reoccupied by the Museum and opened 

 to the public, after certain additions and improvements in the in- 

 stallation had been made. 



Geology. — The additions to the collections in this department 

 during the year were but 135 lots, aggregating an approximate total 

 of nearly 31,000 specimens. This number, although somewhat less 

 than that of the preceding year, is, in part, compensated for by the 

 unusual value of sundry individual specimens. Among these may be 

 mentioned examples of tungsten minerals both from domestic and 

 foreign sources, including a magnificent specimen of scheelite pre- 

 sented by Dr. J. Morgan Clements, of New York City, and upward 

 of 16.5 kilogi'ams of the extraordinary meteorite which fell at Cum- 

 berland Falls, in Whitley County, Ky., on the 9th of April, 1919. 



The availability of the Frances Lea Chamberlain fund has 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 are among the 

 more important additions. 



The Middle Cambrian collections obtained by Secretary Walcott 

 from Burgess Pass in British Columbia number nearly 7,000 indi- 

 vidual specimens, and form an addition of unusual value. The
