art of tablet or card weaving were enthusiastically received by the 

 visiting public. 



The Division of History arranged a special temporary numismatic 

 exhibition during coin week, February 15 to 22, through the coopera- 

 tion of the American Numismatic Association represented by its 

 president, Moritz Wormser, of New York City. Three members of 

 the association residing in Washington contributed to this exhibit. 



George H. Russel lent a collection of 250 ancient silver coins. 

 About one-third of these were coins issued by various Greek cities 

 during the period of the finest development of the art of coinage in 

 Greece, many of which were exceptionally well preserved and of 

 special interest to all students of Greek numismatics. The remain- 

 ing two-thirds consisted of Roman consular coins issued by various 

 Roman officials during the latter portion of the republican era, also of 

 exceptional historic and art interest. 



A second contributor to the temporary exhibition was B. M. Comer- 

 ford, who lent an exceptionally fine series of British maundy 

 money beginning with the reign of Charles II, in 1660, and including 

 specimens down to the reign of George V, the last series shown being 

 the issue of 1915. Special interest attaches to the coins of this char- 

 acter and the collection lent by Mr. Comerford during coin week 

 undoubtedly interested many visitors to the Museum. Mr. Comer- 

 ford also lent a series of early Irish silver coins and a series of neces- 

 sity coins struck in Ireland in 1689 under the authority of James II. 

 Nearly every variety of this type of coinage was represented in Mr. 

 Comerford's exhibit. 



The third contributor was Leander McCormick Goodhart of the 

 British Embassy, who lent a very interesting series of 64 British 

 naval medals representing the period of British naval history be- 

 tween 1653 and 1827. The series began with medals of the type 

 issued in commemoration of victories over the Putch during the 

 seventeenth century, and the medals of the eighteenth century in- 

 cluded specimens commemorating the achievements of such famous 

 leaders as Admiral Edward Yernon, Capt. James Cook, and Admiral 

 Horatio Nelson. 



RESEARCHES 



No researches of major consequences have been underway in the 

 Divisions of Mineral and Mechanical Technology. Since the death 

 of George W. Spier, who was custodian of watches, the division 

 has had no horology specialist. Toward improving this condition, 

 the curator, C. W. Mitman, has devoted much attention to horology 

 and has made a study of several private horological collections and 

 libraries in Lancaster, Pa., and New York City. He has, further- 

 more, spent considerable time in the preparation of manuscript for
