steamer Albatross Philippine expedition, and many sendings that 

 have come in from time to time from various sources, readily place 

 the collection of the National Museum now way ahead of any other 

 museum as far as Philippiniana are concerned." 



Next in value to the collections purchased with the Chamberlain 

 fund is the anatomical material obtained by John B. Henderson in 

 Jamaica. This is of unusual importance, as it was collected with 

 special reference to the needs of the Museum. A particularly inter- 

 esting accession is represented by 187 slides presented by Dr. E. M. 

 Bluestone, of Mount Sinai Hospital, New York City, showing various 

 stages of development of the malarial parasite. This valuable col- 

 lection was made by Doctor Bluestone in one of the Army camps 

 during the war. In some instances specimens were taken at stated 

 intervals between chills to show the different stages in the develop- 

 ment of the trophozoite in the blood of man. No less than 23 gifts 

 and 1 exchange are further mentioned by the curator as worthy of 

 special notice. While they can not be described here, their mere 

 number indicates a gratifyingly cordial relationship between our 

 division of mollusks and the shell-loving public. 



Echinoderms. — By transfer from the Bureau of Fisheries, the 

 Museum has received two important collections made by the Alba- 

 tross and in part determined by A. Agassiz, H. L. Clark, and H. 

 Ludwig. Dr. C. J. van der Horst, of Amsterdam, Holland, pre- 

 sented 29 brittle stars from the island of Curacao, and the curator 

 contributed 6 sea urchins from southeastern Africa. 



Plants. — The National Herbarium has been increased during the 

 past fiscal year by gifts, exchanges, and purchase of specimens, and 

 by transfer of material from several Government departments, 

 especially the Department of Agriculture. The more important ac- 

 cessions of the year are as follows : 43,843 specimens transferred by 

 the Bureau of Plant Industry, United States Department of Agri- 

 culture. These include 33,750 specimens, comprising three-fourths 

 of the Buchtien Herbarium (ref en-red to elsewhere) ; 6,000 speci- 

 mens collected by Ivar Tidestrom in the western United States ; 2,000 

 mounted grasses from eastern Asia, collected by A. S. Hitchcock; 

 and 1,327 miscellaneous mounted grasses; 12.500 specimens, largely 

 from tropical America, purchased from Dr. Otto Buchtien, La Paz, 

 Bolivia (these with the 33,750 specimens mentioned above comprise 

 the Buchtien Herbarium purchased jointly by the United States 

 National Museum and the United States Department of Agriculture) ; 

 7,000 specimens collected for the Museum by Paul C. Standley in 

 El Salvador, Honduras, and Guatemala (this material represents 

 a full set of the collections made in Central America by Mr. Standley 

 during the last half of the year on behalf of the National Museum,
