Obituary. 



Dr. Carlo Riva, Docent in petrography and Assistant in the 

 mineralogical laboratory of the University of Pavia, was killed 

 by an avalanche June 3d, during the ascent of the Monte Grigna, 

 southeast of Lake Como. Dr. Riva was one of the most promis- 

 ing of the younger petrographers and mineralogists of Italy and 

 had already published several papers describing rocks from the 

 Monte Adamello and other regions in the Alps, from Italy and 

 Sardinia ; he was also correspondent for the Zeitschrif t fitr 

 Krystallographie, and gave promise of a long and productive 

 career. His American friends, who were familiar with his charm- 

 ing personality, will learn with deep regret of his untimely end.
