24 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1946 
mollusks were added to the collections. The helminthological collec- 
tions were materially enhanced by the generous bequest of the life- 
time collections of the late Dr. Henry Baldwin Ward, distinguished 
parasitologist; 8,000 lots of helminths, including many types, were 
received from Professor Ward’s daughter. 
The number of plants received jumped from about 30,000 in 1945 
to nearly 42,000 in 1946, largely as a result of extensive collections 
made by members of the armed forces while serving in the Admiralty, 
Aleutian, Caroline, Galapagos, Solomon and Philippine Islands, 
Guam and other Marianas, Japan, Okinawa, New Guinea, Burma, and 
France. The herbarium received 3,100 Burman plants by transfer 
from the U.S. A. Typhus Commission, and over 800 Ecuadorian plants 
from the Foreign Economic Administration. Other important lots, 
from private donors, came from Colombia, Venezuela, and México. 
Noteworthy botanical collections totaling 6,800 specimens were made 
for the Museum in Panama and the Dominican Republic. In addition, 
about 5,000 plants were added to the herbarium as a result of ex- 
changes arranged with other institutions, in Europe, South America, 
Cuba, Canada, and the United States. 
Geology.—The department of geology accessioned 45,000 specimens 
during the year, nearly double the number for last year, about 90 
percent of these being assigned to the division of invertebrate pale- 
ontology and paleobotany. 
The mineral collection continued its growth, partly through the 
several Smithsonian funds available for the purchase of specimens, 
but largely through gifts. Three new minerals not hitherto repre- 
sented—cattierite, valsite, and salesite—were donated, while the new 
species sampleite was obtained by exchange. The mineral collection 
of Dr. Whitman Cross, containing specimens from many old classical 
localities in Europe and the western United States, came as a gift and 
added much historically interesting material. Geological field work 
in México by Curator W. F. Foshag yielded fine sal-ammoniac crystals 
and other sublimates from the newborn volcano Paricutin, and ex- 
amples of rare mercury minerals from Huahauxtla, Guerrero. The 
principal addition to the rock series also came from Dr. Foshag’s 
visits to Paricutin and comprised an extensive collection of lavas, ash, 
and other eruptive products. Extensive sets of mercury ores, cop- 
per, and fluorspar were also included in Dr. Foshag’s Mexican ma- 
terial. 
Three meteorites not previously represented in the Museum’s series 
were added: A slice of the Pine River, Wis., meteorite; a 3,576-gram 
specimen of the Dimmitt, Castro County, Tex., fall; and a piece of the 
Livingston, 'Tenn., occurrence.
