26 REPORT OF NATIONAL MUSEUM, 1&15. 



Mr. George G. Heye, with which considerable progress was made; 

 and to " Old Americans," or American families of at least three 

 generations in this country, the latter being in continuation of work 

 previously begim. One hundred males and the same number of 

 females have been studied and a resume of the results, intended for 

 presentation at the forthcoming International Congress of American- 

 ists, is in course of preparation. 



Dr. Hrdlicka was in San Diego, Cal., from November 18th to 

 January 18th, installing the anthropological exhibits at the exposi- 

 tion, and he also lectured on subjects connected with his division in 

 several western cities. Later in the year he visited a number of mu- 

 seums for the purpose of examining skeletal remains of eastern 

 Indians, and made a trip to the White Earth and Leech Lake reser- 

 vations in Minnesota for the Department of Justice, with the object 

 of determining the proportion of pure and mixed bloods among the 

 Chippewa Indians. 



Mechanical technology. — The additions of the j^ear, comprised in 

 40 accessions, included many articles of exceptional value. Of great- 

 est interest was a collection of 280 pieces of experimental phono- 

 gi'aphic apparatus, and several relics connected with the early history 

 of the telephone, the gift of Dr. Alexander Graham Bell. Among the 

 other noteworthy acquisitions were many surveying instruments and 

 7 pocket chronometers of historical importance, transferred by the 

 U. S. Coast and Geodetic Survey ; 23 guns and 1 sword deposited by 

 the Navy Department; 1 United States magazine rifle, deposited by 

 the War Department; an equatorial sextant and solar compass pre- 

 sented by Miss Elizabeth B. Burt, of Washington ; a sundial calcu- 

 lated for Valencia, Spain, the gift of Mr. Claude L. WooUey, of 

 Baltimore, Md. ; a gasoline automobile of date 1896, contributed by 

 the Olds Motor AVorks, of Lansing, Mich. ; a comptometer presented 

 by the Felt and Tarrant Manufacturing Co., of Chicago, 111.; a 

 talking machine donated by the American Graphophone Company, 

 of Bridgeport, Conn. ; and 6 target rifles lent by the National Rifle 

 Association of America. 



Good progress was made toward perfecting the installation of the 

 exhibition collections, in connection with which it was necessary to 

 bring more recent acquisitions into proper relationship with earlier 

 ones, and as a whole a more systematic arrangement of the material 

 has been secured. Important readjustments were effected in the col- 

 lections of telephone apparatus, talking machines, watches, railroad 

 apparatus and firearms. Gratifying progress was also made in the 

 labeling of exhibits and in collecting data required in perfecting 

 the records. 



Investigations relating to the various subjects coming within the 

 scope of the division, by the curator, Mr. George C. Maynard, re-
