Ayer Pioneer Hose Company of Phcenix, Arizona ; specimens of the 

 Allegan, Oakland and St. Genevieve County meteorites ; representa- 

 tive series of quartz geodes of the Keokuk beds ; the collection of 

 fossil dinosaurs obtained by Assistant Curator Riggs, and a repre- 

 sentative series of cave formations obtained by Curator Farrington, 

 have been added to the collections in the department of Geology. 

 Through the generosity of Mr. W. J. Chalmers, funds were provided 

 which enabled the department to prepare a collection of crystals of 

 the United States minerals for exhibition at the Paris Exposition. At 

 the close of the exposition the collection will be returned to the 

 Museum. It was awarded a silver medal.
