REPORT OF NATIONAL MUSEUM, 1921. 41 
and Surgeons of Columbia University, New York City, through 
Prof, George 5. Huntington. Smail portions of this material were 
already in our possession as the result of exchanges in previous years; 
it consists of the identified skeletal remains of upward of 1,500 indi- 
viduals of known sex, age, color, nationality, and cause of decease. 
It includes in ample number for all desired information representa- 
tives of the different parts of the white race which are entering into 
the composition of the American people, and as such will have a con- 
stantly increasing value for mutual comparisons. The scientific im- 
portance of this material can hardly be estimated, and it is not too 
much to say that it practically doubles the value of our collection. 
No other collection of equal extent is in existence. Another collection 
of importance is that of 27 human brains donated to the Museum by 
Dr. Edward Anthony Spitzka, Washington, D. C. The next collec- 
ttion of note is that of 10 Arikara skulls and 3 skeletons donated 
by the University of South Dakota, through Prof. Freeman Ward, in 
return for a report on their collections. These specimens are in 
good condition and fill what was almost a complete void in our col- 
lections. Mention should also be made of a quantity of skeletal 
material collected in Tennessee by Mr. W. E. Myer, of Nashville, 
Tenn., and transmitted to the Museum by the Bureau of American 
Ethnology. 
In addition to the above there were a series of smatler accessions of 
crania and skeletons from various parts of this continent. 
A loan collection of rare oriental rugs was received in art textiles, 
replacing those hung last year. This collection was sent by a public- 
spirited, Washingtonian to be exhibited for the benefit of the public. 
The weavings number 38 and typify the chief varieties of these 
artistic textiles. 
The section of musical instruments reports that the Worch col- 
lection of pianos has been enriched by the gift of a copy of the 
harpsichord used by Johann Sebastian Bach, the great composer. 
The original is in the Museum at Stuttgart, Germany. Two copies 
were permitted to be made and one of these is now displayed in the 
Worch collection in the National Museum. The instrument has four 
pedals and four stops, a surprising mechanical equipment for the 
period. A dulcitone, an instrument whose sounding apparatus is a 
succession of graded tuning forks, was procured by Mr. Worch from 
Glasgow, Scotland. Eleven other valuable pianos, illustrative of the 
history of this instrument, were added to the collection by Mr. Worch. 
A piano handsomely decorated by Cottier of New York was given by 
Mrs. Gouverneur Morris, Washington, D. C.

late Dwight J. Partelio and whose disposition has attracted wide
