Through the gift of Miss Annie M. Alex- 

 ander who has pledged more than $8,000 an- 

 nually for a period of years, the University of 

 California has been enabled to organize a Mu- 

 seum of PalsBontology. Effected primarily for 

 the advancement of research in palseontolog'y 

 and historical geology, it is expected that the 

 investigators on the fossil mammals and fossil 

 reptiles of the Pacific coast, begun by Presi- 

 dent John Campbell Merriam, of the Carnegie 

 Institution of Washington, formerly professor 

 of paleontology and historical geology and 

 dean of the faculties, will be continued in the 

 new department. Dr. Bruce L. Clark, assistant 

 professor of ipalseontology, has been named di- 

 rector of the museum, while E. L. Furlong, as- 

 sistant in palaeontology, is expected to be ap- 

 pointed curator of the vertebrate collections. 

 Included in the staff will be Chester Stock, in- 

 structor in palaeontology, and Mr. Charles 

 Camp, to be named vertebrate palaeontologists. 

 Comprising thousands of specimens of fossil 

 plants, vertebrates and invertebrates, the pres- 

 ent collections will be turned over to the mu- 

 seum, and the department of paleontology will 

 cease to have a separate existence. Proper or- 

 ganization of this and other collections is 

 stated to be one of the most important pur- 

 poses for which the museum has been founded.
