20 REPORT OF NATIONAL MUSEUM, 1921, 



National Museum sj^stem, since the Freer Gallery is dependent upon 

 the Museum plant for heat, light, and power. 



LOEB COLLECTION OF CHEMICAL TYPES. 



Practically no progress was made this year in establishing the 

 Loeb collection of chemical types owing to the diificulty experienced 

 in moving to Washington the steel storage cabinet and other prop- 

 erty purchased from the Morris Loeb fund, and which are still in 

 the library of the Chemists' Club of New York City. 



Numerous .specimens for the type collection have been promised 

 and will be turned over to the National Museum as soon as the 

 storage cabinet, especially built to protect delicate specimens from 

 deterioration, has been received and installed in its permanent place. 



COOPERATION OF THE EXECUTIVE DEPARTMENTS. 



Belonging as it does to the Nation, the National Museum receives 

 important assistance from other governmental agencies. Particularly 

 was this true during the fiscal year 1921. Credit is due to the Navv 

 Department for transporting and installing in the Museum building 

 many attractive exhibits in the World War collections; to the War 

 Department for similar service, including the detail to the Museum 

 of one officer for several months ; to the Dei^artments of Agriculture, 

 Commerce, and the Interior and the Bureau of American Ethnology 

 for many valuable contributions of specimens and much assistance 

 in classifying and labeling objects in the Museum; to the Interior 

 Department also for transferring exhibition cases no longer needed 

 by it; and to the Post Office Department for large series of postage 

 stamps. 



This cooperation is not entirely one-sided. The Museum renders 

 aid to the executive departments whenever possible, as evidenced 

 by the work of Dr. Ales Hrdlicka for the Department of Justice, by 

 which over a million of dollars in land and money was saved for the 

 Indians. 



PARTELLO REQUEST. 



Under the terms of the will of Dwight J. Partello, who died on 

 August 13, 1920. the Museum is bequeathed his collection of musical 

 instruments, bows, and cases, gathered during many years of collect- 

 ing, 37 paintings, a gold and silver box or casket presented to Mr. 

 Partello by the Czar of Russia, and a diploma and medal awarded 

 him for his exhibit of violins at the Chicago Exposition in 1893. 

 The unique collection illustrating the Italian school of violins is well 

 known and of great intrinsic value. It numbers 25 instruments 

 of the violin family, made by the best masters in pure construction, 

 including Amati, Stradavari, Bergonzi, Guarnerius, and others. At 

 the end of the fiscal year Mr. Partello's estate had not been settled.
