examinations regarding the antiquity of man in that country, and at 
the close of the year satisfactory progress had been made. 
Technology—The most important addition to this division was a 
collection received from the Navy Department, consisting of 82 rifles, 
carbines, and muskets, which had been kept as an historical exhibit 
at the League Island Navy Yard, Philadelphia, for several years. 
A few of the most interesting examples are typical pieces from the 
Virginia Manufactory, Richmond, Virginia, of dates 1816, 1818, and 
1819; a musket from the Palmetto Armory, Columbia, South Caro- 
lina, 1852; several Harpers Ferry muskets, including the rare Ply- 
mouth pattern of 1858; a Whitneyville rifle of 1863; a rare breech- 
loading rifle made by A. H. Waters & Co., Milbury, Massachusetts; a 
standard United States Army rifle altered by the Confederate Govern- 
ment and stamped ‘‘Cook and Brother, Athens, Georgia, 1864;” a 
Potsdam musket of 1833; Tower muskets and carbines of various 
lengths and calibers, some of early dates; and good examples of Colt, 
Sharps, White, and Maynard arms. Two sets of aerodynamic models 
in wood, devised by Dr. Albert F. Zahm in 1903, in the laboratory of 
the Catholic University of America, Washington, District of Colum- 
bia, and employed by him for determining the atmospheric resistance 
of symmetric spindles and wedge-shaped models, and the best form of 
hulls for motor balloons and flying machines, have been deposited by 
Dr. Zahm. A number of interesting sundials designed and con- 
structed by Mr. Claude L. Woolley, of Baltimore, Maryland, and pre- 
sented by him, are especially instructive as showing the different 
forms of dials adapted to the latitude of the Panama Canal Zone, 
8° 57’ north, Washington, District of Columbia, 38° 55’ north, and 
Nome, Alaska, 64° 30’ north. Mr. Woolley has also contributed a 
vertical sundial adapted to the latitude of Boston, 40° 21’ north, and 
a noon mark to be used in any latitude. A model likewise received 
from him represents a rare dial known as the reclining cross type, 
which is made for the latitude of New Orleans, 29° 55’ north, and 
bears the inscription, ‘‘ Aspiciendo senescis.”’ 
A pin machine, the gift of the Howe Manufacturing Company, 
Derby, Connecticut, invented by Dr. John Ireland Howe in 1835, is 
said to be the first successful machine constructed for automatically 
making complete pins. It was put in operation by this company in 
1838, was kept in service until about 1865, and had a capacity of 60 
pins a minute. Models of the unarmored protected cruiser Atlanta 
and the armored cruiser Pennsylvania were deposited by the Navy 
Department. A most noteworthy and valuable collection of 153 
chronometers and watches, comprising many superior, full-jeweled, 
and finely finished timepieces, the productions of the best makers ot 
their time, American and foreign, was donated by Dr. Thomas Feather- 
stonhaugh, of Washington, District of Columbia. Sixty-four articles,
