REPORT OF NATIONAL MUSEUM, 1918. 21 



Mr. E. J. Collett, through Miss R. N. Brady; two supernumerary 

 teeth, and one cast of an upper jaw, from Mr. W. D wight Pierce; 

 an important skull, with two other fragmentary crania, and one 

 lower jaw, from Dr. William J. Morton ; and a number of anatomical 

 specimens from Dr. D. S. Lamb. Two casts of supposedly early man 

 were added to the collection by purchase. 



General work on the collections was carried forward vigorously, 

 with the result that at the close of the year at least three-fourths of 

 the material was in such good shape as to require practically no 

 further attention. 



Mechanical technology. — The accessions for the year were above 

 the average in number and of more than general interest and scien- 

 tific value. Preeminent was the original full-size Langley flying 

 machine of 1903, and a duplicate set of cylinders for the engine, 

 deposited in the custody of the Museum by the Smithsonian Insti- 

 tution. The original engine had been in the Museum for some years. 

 Begun in 1898, by former Secretary S. P. Langley, for the War De- 

 partment, in the interest of national defense, this was the first aero- 

 plane capable of sustained free flight carrying a man. The machine 

 was suspended from the ceiling in the east hall of the arts and indus- 

 tries building, and the engine was placed in a floor case below, where 

 it can be inspected to better advantage. 



A very interesting piece of apparatus, designed for magnetizing 

 steel compass needles, etc., was lent by Mr. W. R. Protsman, on be- 

 half of the owner, Dr. Frederick L. Koontz, United States Army. 



Of the numerous and important contributions to the firearms 

 series and firearms appliances the following deserve special mention : 

 Two revolvers, a made-up gun, and 21 swords mostly of Santo Do- 

 mingo manufacture, from the collection of 27 weapons donated by 

 Lieut. Col. G. C. Thorpe, United States Marine Corps; modern 

 firearms of English and American make, presented by Col. Henry 

 May; two muskets, a United States artillery sword, and a United 

 States cavalry sword, transferred from the Library of Congress; a 

 British Enfield rifle, model of 1914, given by the Winchester Re- 

 peating Arms Co., through Mr. Henry Brewer ; a Springfield musket 

 of 1838, a Springfield breech-loading rifle, model of 1844, a United 

 States Army musket, a Sharp's breech-loading rifle, model of 1859, 

 a Colt's single-action revolver, three single-barrel pistols, and an 

 iron bullet mold, from the collection contributed by Dr. Adam 

 Heiner; an up-to-date high-power sporting rifle, from the Newton 

 Arms Co. (Inc.) ; three guns of historical interest (a European air 

 gun, a bell-mouth swivel gun, and an oriental rifle) said to have 

 belonged to the late William Cost Johnson, Member of Congress 

 from Maryland, 1833-43, presented by the heirs of Mr. Johnson 

 through Mrs. E. Cuyler Wight; a knife pistol, contributed by Mr.
