At the request of the Museum, Lieut. George L. Dyer, hydrographer, 

 furnished a copy of the British admiralty chart, and also charts of 

 Queen Charlotte Islands, Hecate Straits, and Dixon Entrance, for use 

 in the Ethnological Department of the Museum. 



Dr. J. M. Flint, U. S. Navy, has contributed valuable services as 

 Honorary Curator of the section of Materia Medica. 



DEPARTMENT <>F THE INTERIOR. 



U. 8. Geological Survey.— The Museum acknowledges with gratitude 

 and pleasure the valuable assistance of the Survey, whose operations 

 are in many respects closely related to the work of the Museum. The 

 researches of the geologists connected with the Survey are of especial 

 value by reason of the large collections which are made, and which 

 after being worked over and described are transferred to the Museum 

 collections. The past year has been, perhaps, as notable as any in the 

 acquirement by the Museum of valuable and interesting collections 

 from this source, as will be seen from the appended statement. 



The U. S. Geological Survey presented several pieces of Iucliau pottery, and 

 a number of stone relics fouud in Prentiss County, Mississippi ; a specimen of native 

 platinum from Washington Territory; rock specimens from California, collected by 

 J. S. Diller; a large collection of rocks (comprising about 2,000 specimens) of the

 Becker. This collection is more fully described- in Mr. Becker's report of the geology 

 of this region (Monograph in, U. S. Geological Survey), and also in Messrs. Hague
