62 Report of the President 



Greene collection contains approximately 400,000 well pre- 

 served specimens, chiefly corals from the Devonian reef at 

 the Falls of the Ohio, opposite Louisville, Ky. The 

 Important Museum is fortunate to have secured this collection, 



/Vcccssiofis 



for it is one of the few fine collections of its kind 

 in the United States. It represents the life work of one man 

 and a large portion of that of his son. Approximately 500 

 species have been described and figured in G. K. Greene's "Con- 

 tributions to Indiana Palaeontology." The types of these 

 species form a valuable part of the collection. The W. J. 

 McConathy collection also consists chiefly of fossil corals from 

 the Falls of the Ohio, and numbers approximately 7,000 speci- 

 mens. With the addition of these two collections, the Museum 

 will become a Mecca for students in fossil corals. 



Other important accessions are : A series of beautifully pre- 

 served Tertiary fossils from Santo Domingo ; a 70-pound mass 

 of telluric iron from Ovifak, Disko Island, Greenland; the 

 main portion of the meteorite fall at Plainview, Texas; speci- 

 mens of the Scott City, Kansas, and Cookville, Tennessee, 

 meteorites. 



The extension of the fifth floor over the stairway at the 

 northern end of the south central wing early in 

 Fifth Floor {he year provided much-needed space for a geologi- 

 cal laboratory. 

 In closing this report I desire to place on record my appre- 

 ciation of the faithfulness and efficiency with which all the 

 assistants employed in the department have discharged their 

 various duties.
