20 REPORT OF NATIONAL MUSEUM, 1921. 
National Museum system, 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 difficulty 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 Navy 
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 Departments 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, 87 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.
