30 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1918. 



during the Revolution, and a spyglass and steel tape measure used 

 by Lieut. Col. Isaac Roberdeau, when assisting in laying out the 

 city of Washington, were among objects lent to the Museum, as was 

 also a portion of the set of chinaware presented by Gen. Lafayette 

 to Mr. and Mrs. George Graham, of Virginia. 



To the historical costumes were added knee breeches and waist- 

 coat worn during the Revolution by Col. Tench Tilghman; the 

 official costume and sword of William L. Dayton, American minister 

 to France in 1861-1864; the official costume and sword of William L. 

 Dayton, jr., secretary to the American Legation in Paris during that 

 period ; and a satin dress worn by Mrs. Annette Henry Alger, wife of 

 Russell A. Alger, Secretary of War, 1897-1899. 



Particular^ noteworthy is the collection of medallic Lincolniana 

 assembled through many years by Mr. Robert Hewitt, of New York 

 City, and presented by Mrs. Hewitt, consisting of 1,200 medallic 

 souvenirs, including medallions, plaques, medals, coins, tokens, and 

 badges. The Robert Hewitt collection is remarkable for the very 

 wide range of subjects and types of numismatic material which it 

 covers, and constitutes an epitomized medallic record of the career 

 of President Lincoln. The United States Mint contributed a large 

 series of bronze replicas of United States military and naval service 

 medals, commemorative medals, and medals of award. 



The philatelic material in the Museum was augmented by 3,186 

 specimens. Of the 2,706 transferred from the Post Office Depart- 

 ment, 1,506 represented new issues received by the Department from 

 the International Bureau of the Universal Postal Union. 



Biology. — While the various divisions of this department report a 

 decrease both quantitatively and qualitatively in the additions of the 

 year, it is notable that they relate in most instances to the floras and 

 faunas of foreign lands remote from the scene of war and war 

 preparations. 



Another trip to Haiti by the indefatigable collector and generous 

 friend of the Museum, Dr. W. L. Abbott, resulted in important 

 material for the Museum from that and adjoining islands, including 

 new and rare forms of birds and reptiles. Mr. H. C. Raven, operat- 

 ing under the auspices of Dr. Abbott, continued collecting birds and 

 mammals in Celebes, moving toward the middle of the island and 

 visiting one or more of the high peaks. He obtained interesting 

 species and genera not found at lower levels, some of the species 

 apparently new to science and several genera new to the Museum 

 collection. Coming from the border country between north and south 

 Celebes, the faunas of which differ considerably, the full significance 

 of the series can only be appreciated when the entire Celebes 

 collection has been carefully studied.
