 photographs of Izalco were taken by Dr. Sharat K. Roy, Chief Curator of Geology). 



Forslev, recently appointed Associate Curator of Mineralogy and 

 Petrology, is now engaged in testing the equipment. He is also 

 familiarizing himself with our mineral and rock collections pre- 

 paratory to his participation in the exhibition work now in progress 

 in the new Hall of Meteorites and Minerals (Hall 35) . His research 

 at present concerns the stability of minerals to weathering. 



Dr. Sharat K. Roy, Chief Curator of Geology, devoted part of 

 his time to duties connected with the installation of meteorites in 

 Hall 35. In his revisionary work on five papers, three of them 

 dealing with volcanoes and volcanism and two with meteorites, 

 he was greatly aided by Departmental Artist Maidi Wiebe, who 

 translated a series of German articles into English. The new data 

 added to the volcano papers were secured while Chief Curator Roy 

 was engaged in field work in Mexico, Guatemala, and El Salvador 

 during August, September, and October. The preparation of an 

 English translation of Karl Sapper's Los Volcanoes de la America 

 Central in collaboration with Dr. Ortrud Dieterichs of Institute

 going over the translation to add new data and recent photographs 

 and to delete out-of-date materials. The compilation of a catalogue
