REPORT OF NATIONAL MUSEUM, 1913. 75 



mens of cliiysoprase and rutile in quartz, pink tourmaline with crystals 

 of lepidolite, a specimen of manganese from Panama, and six speci- 

 mens of polished agate constituted a valuable gift from Mr. A. E. 

 Heighway, of New York City, to whom the Museum was also indebted 

 for the loan of 3 tourmaUne crystals and 4 cut pieces of gem chryso- 

 prase, the latter being exceptionally fine examples. Eleven speci- 

 mens of gems, including a beautiful suite of poUshed black opals from 

 New South Wales and jade from China, were obtained by purchase. 

 All of the important accessions in petrology were transmitted by the 

 Geological Survey and comprised the following, namely: One hun- 

 dred and seventy-one specimens illustrating the geology and ore 

 deposits of the Park City district, Utah, described in Professional 

 Paper No. 77 of the Survey, by Mr. J. M. Boutwell; 125 specimens 

 of rocks from the Northeastern and RepubUc mining districts of 

 Washington, described in a bulletin of the Survey now in press, by 

 Prof. Waldemar Lindgren and Mr. Howland Bancroft; and 451 rock 

 and ore specimens from the mining districts of New Mexico, described 

 in Professional Paper No. 68 of the Survey, by Prof. Lindgren, Mr. 

 Louis C. Graton and Mr. Charles H. Gordon. 



The reorganization of the collections in this division, following the 

 same Hnes as in systematic and appUed geology, was carried well 

 toward completion. A number of very desirable additions were 

 made to the exhibition series of minerals, and an extensive display of 

 petrological material was installed. The work of rearranging and 

 labeHng the reserve series, including the cleaning of specimens, was 

 sufficiently advanced to make these collections convenient of access, 

 the specimens most needed for reference being provided for in and 

 adjacent to the laboratories in the third story and the remainder, 

 constituting the greater bulk of the material, being stored in cases 

 in the attic. The segregation of the dupHcate specimens was also in 

 large part accomphshed. The work of the year related very largely 

 to the petrological collections, the minerals having previously received 

 most attention. The former are of very considerable extent and in- 

 clude many type sets from the Geological Survey. The labehng of 

 the exhibition series as now constituted was completed, and card 

 catalogues covering the same, as also the reserve series, thes type 

 specimens and the dupHcates, have been prepared. 



The comprehensive monograph on the turquois, mentioned in the 

 last report, was completed by Dr. Pogue, who also made a crystal- 

 lographic study of cerussite. 



Invertebrate 'paleontology. — ^Most prominent among the additions to 

 the section of invertebrate paleontology were three transfers from the 

 Geological Survey. The first of these comprised the type, figured 

 and other important specimens, to the number of 1,952, described 

 by Prof. Henry S. Williams in two monographs now in press by the
