62 Report of the President 



the relatively rare copper arsenate chalcophyllite. The 

 Chuquicamata series contains much material of high scien- 

 tific interest. Through the gift of Mr. W. Spencer Hutchin- 

 son, the collection has acquired typical specimens of hewet- 

 tite and pascoite from Mina Ragra, Peru. Mr. Breck Trow- 

 bridge has contributed an unusual specimen of brucite from 

 a Manhattan Island locality. The Gem Collection has been 

 enriched through the gift by Mr. Charles Lanier of the ex- 

 quisite chalcedony figurine "Pas de Danse" by M. Tonnelier, 

 which was formerly deposited by him as a loan to the Col- 

 lection. This statuette, which was acquired by Mr. Morgan 

 and given by him to Mr. Lanier, represents the highest ex- 

 pression of the art of the gem engraver and will occupy the 

 place of honor in the new installation of the Gem Collection. 

 Another notable addition to the Gem Collection is the pen- 

 dent necklace assemblage of aquamarines, diamonds, sap- 

 phires and garnets which constitutes the official trapping of a 

 Vizier of Morocco of the eighteenth century and which was 

 acquired through the gift of Mr. M. L. Morgenthau. Through 

 the Matilda W. Bruce Fund the Mineral Collection has ac- 

 quired a number of rare and important mineral occurrences 

 from Hungary, Bohemia, Czechoslovakia and Austria.
