SECRETARY'S REPORT 67 



Likewise, a plan to divide the Department of Geology into two depart- 

 ments, Mineral Sciences and Paleobiology, was approved on August 

 20, 1963, and the reorganization became effective on October 15, 1963. 

 The diversity of disciplines in the old geology department made the 

 partition logical and desirable. The purely physical subjects of 

 mineralogy, petrology, and meteoritics are now separated from the 

 biological subjects of paleontology and ecology. The Department of 

 Mineral Sciences consists of three divisions, Mineralogy, Meteorites, 

 and Petrology. The Department of Paleobiology consists of four 

 divisions : Invertebrate Paleontology, Vertebrate Paleontology, Paleo- 

 botany, and Sedimentology. 



By direction of the Secretary, a new system was inaugurated in May 

 whereby certain administrative duties within the Museum are rotated 

 in order to free senior staff members for research and publication, 

 permitting others to participate more widely in administration. While 

 it is believed that it is at the department level that such moves are 

 most needed, the designation of more than one full curator within a 

 division will make it possible to rotate appointments in the divisions 

 as well. This will be done by detailing a member of the division 

 curatorial staff to serve as "curator in charge." The curator formerly 

 in charge of that division will either become a senior scientist or his- 

 torian or continue on the personnel rolls as a full curator. Such 

 rotations may be scheduled by museum directors in response to recog- 

 nized needs, although they will not become a matter of set schedule 

 or routine. The title "head curator" has accordingly been discon- 

 tinued, and the title for the administrative head of each department 

 will be "chairman." The former chairman of a department may be 

 appointed a senior scientist or continue to serve as a full curator, 

 upon the recommendation of his Museum director. 



During fiscal year 1964 the following appointments were made to 

 the scientific staff of the Museum of Natural History: Dr. Wallace R. 

 Ernst, associate curator of phanerogams, on July 29, 1963; David B. 

 Lellinger, associate curator of ferns, on August 26, 1963 ; Dr. Richard 

 C. Froeschner, associate curator in charge of Hemiptera, on August 

 26, 1963 ; Dr. Richard L. Zusi, associate curator of birds, on September 

 3, 1963 ; Dr. Richard B. Woodbury, associate curator of archeology, on 

 December 15, 1963 ; Dr. Clayton E. Ray, associate curator of vertebrate 

 paleontology, on December 18, 1963; Dr. Dan H. Nicolson, associate 

 curator of phanerogams, on January 5, 1964; Dr. David L. Pawson, as- 

 sociate curator of marine invertebrates, on May 20, 1964 ; Dr. Walter H. 

 Adey, associate curator of paleobotany, on June 30, 1964; and Dr. 

 Richard H. Benson, associate curator of invertebrate palentology, 

 on June 30, 1964.
