from Iowa and Illinois purchased in 1878, and the Braun collection of 

 fossil crinoidea, purchased in 1880. 



EXPEDITIONS 



The various expeditions by Associate Curator Hovey added greatly 

 to the value of the department, both in extent of collections and the 

 scientific data obtained. The publication of the investigations of 

 the volcanic phenomena following the eruptions in Martinique and 

 St. Vincent in 1902 placed the name of the Museum among the leading 

 contributors to volcanology. 



SCIENTIFIC STAFF 



Professor Robert Parr Whitfield has been in the active service of 

 the Museum since 1877. The Museum's report for that year states 

 that "the purchase of the Hall Collection has made the Departments 

 of Geology and Palaeontology so important that the services of a special 

 Curator have been required and Professor R. P. Whitfield has been Robert Parr

 himself assiduously to the cataloguing and arranging of the collec-

 Curators, and he himself has made many valuable contributions to it. 

 The Department of Marine Invertebrate Zoology was also under his 

 charge from 1890 until 1901, when it was established as a separate 

 Department under Dr. Bumpus. Professor Whitfield was Curator of 

 Mineralogy and Conchology also until they were made a separate 

 department in 1901.
