 from Baja California. 



A suite of well-crystallized minerals from the lead-zinc mines of 

 Trepca, Yugoslavia, a group of brown barite crystals from Elk Creek, 

 S. Dak., and a tliorianite crystal, about an inch cube, were added to

 negatives of photomicrographs of meteoric iron. By exchange the 

 Museum received from Tohoku University, through Prof. Kenzo Yagi, 

 a representative set of rocks from the new Japanese volcano Syowa 

 Sinzan, Hokkaido. Other important additions to the petrological 

 collections were a series of rocks illustrating the petrology of the Ha-
