A N:o 1) Ignéous Rocks of Sviatoy Noss in Transbaikalia. 
the Namama region between the Bargousin and the Upper 
Angara rivers. — The investigation dealt with in the pre- 
sent abstract was carried out in the Mineralogical and Geo- 
logical Institute of the University of Helsingfors, the expen- 
ses for the chemical analyses being paid for by the Moscowian 
Expedition. The work was finished and the manuscript 
sent to Moscow in 1916 to be printed there together with 
the reports of the other participants. This was, however, 
prevented by the well-known political events in Russia, and 
therefore this abstract now appears. To my dear fellows 
on the journeys in 1914 with whom I, during long years, 
have had no communication, I send my best greetings. 
The Mineralogical and Geological Institution of the 
University of Helsingfors. February, 1921.
